GX460 Control Arms: Best Upper & Lower Picks (2010-2023)

Short version: if your GX460 is lifted and the front end won't align or the upper ball joint is binding, start with new front upper arms. On a 2010-2021 GX460, our pick is the Bilstein B8 51-304690. On a 2022-2023, run the SuperPro TRC6480 fixed offset uppers. For a stock-height 2010 that just needs fresh OEM-style arms, the SuperPro TRC491 is the easy button. If you need more alignment range at the bottom of a KDSS truck, the SuperPro TRC494 lowers (camber and caster adjustable) are the ones we'd bolt on.

Which GX460 do you have? Pick the right arm first

Every arm we carry for this truck is a front arm. The GX460 runs a double-wishbone front end with coil springs and a stabilizer bar. That means one upper and one lower arm per side, and that's where lift geometry gets ugly.

Out back, every GX460 runs a 4-link solid axle. The base and Premium trims use coil springs. The Luxury trim uses an air setup (a pneumatic cylinder assembly). Rear links are a different conversation and aren't covered here.

So to order the right part, you only need to answer three questions:

• What year is it? The Bilstein B8 uppers are listed for 2010-2021. The SuperPro TRC6480 uppers cover 2010-2023. The SuperPro TRC491 OEM-style kit is listed for the 2010 GX460 only.
• Is it lifted or stock height? Lifted trucks want arms with corrected geometry (offset or adjustable). Stock trucks with tired joints and bushings want a factory-style replacement.
• Does it have KDSS? Both SuperPro lower arm kits we sell are built for KDSS trucks. KDSS (Kinetic Dynamic Suspension System) cuts body lean without stiffer springs and dampers. It was standard on the 2014 GX 460. If you're not sure your truck has it, send us your VIN before you order the lowers.

Luxury trims also get AVS (Adaptive Variable Suspension) with Normal, Sport and Comfort modes and electronically controlled dampers. That's a shock and damper system. It doesn't change which front arm you buy.

Best GX460 upper control arms (front, 2010-2023)

The factory upper arm is built for factory ride height. Lift the front with a leveling kit or coilovers and the upper arm angle steepens. Caster drops, camber goes off, and the upper ball joint runs close to the end of its travel. That's when you get a wandery highway feel, alignment specs that won't come back into the green, and joints that wear out early.

The GX is also heavy. A base GX 460 weighs 5,130 lbs at the curb, the Luxury 5,198 lbs, and 52 percent of that sits on the front. That's a lot of weight on a ball joint already running at an angle. Most guys who lift a GX end up in upper arms sooner or later. We cover the general rule in Upper Control Arms for Lifted Trucks: When You Need Them.

Bilstein B8 front upper control arm kit (2010-2021)

The Bilstein B8 Front Upper Control Arm Kit 51-304690 is a tubular arm in black powder-coated 4130 chromoly. Bilstein says the arms correct caster for better straight-line stability on lifted suspension. They also say the improved pivot angles increase wheel travel and take stress off the joints.

The tubular shape opens up room for a bigger spring and shock. It runs greasable polyurethane bushings and heavy-duty ball joints, and every part on the arm is replaceable. Bilstein builds it to work with all of its shocks and coilover kits. Hardware and instructions come in the box.

It suits the 2010-2021 GX owner running a lift who wants a strong, serviceable arm that's set up for caster correction out of the box.

SuperPro TRC6480 fixed offset front upper control arm set (2010-2023)

The SuperPro TRC6480 Fixed Offset Front Upper Control Arm Set takes a set-and-forget approach. The offset is built into the arm instead of dialed in with an adjuster. There's nothing to creep out of spec and nothing to fiddle with. You bolt them on and align the truck.

The big one: it's listed for 2010-2023. That makes it the upper arm for 2022 and 2023 GX460 owners, Black Line Special Edition trucks included, since the Bilstein stops at 2021.

It also fits the guy who'd rather have a fixed arm than tinker with adjustment. Pair it with the SuperPro lowers further down and your whole front end comes from one maker.

Our pick for GX460 upper control arms

If it were our 2010-2021 GX with a lift, we'd run the Bilstein B8. It's chromoly, the bushings take grease, every part can be replaced, and caster correction is part of the design. Here's the deal on newer trucks: on a 2022 or 2023, the SuperPro TRC6480 is the one that fits, and it's a solid arm in its own right.

Best OEM-style upper control arms for the 2010 GX460

Not every GX needs lift arms. Plenty are still at stock height with years of washboard on them. Their bushings are cracked and their ball joints are clunking. If that's your truck, it needs fresh factory-style uppers, and that's what people mean when they search for Lexus GX460 upper control arms OEM.

Pressing new bushings into a worn arm is a half fix. The arm itself and the ball joint still carry all those miles. Replacing the whole assembly is faster and you get new parts all the way through.

SuperPro TRC491 premium front upper control arm kit (2010)

The SuperPro TRC491 Premium Front Upper Control Arm Kit is two complete OEM-style upper arms. SuperPro bushings come pre-installed, along with redesigned, uprated ball joints. It's a standard alignment setup, so the geometry matches factory and it bolts on like the original part.

SuperPro's thinking is simple. New bushings are only as good as the arm you press them into, so they give you a whole new arm. You save the time of pressing bushings and end up with a complete refresh.

This kit is listed for the 2010 GX460 only. It's the right buy for a stock-height 2010 that needs new uppers. It isn't a lift arm. If you're lifted, go back up to the Bilstein or the TRC6480.

Our pick for a stock-height 2010

Easy one. On a stock 2010 with worn uppers, get the TRC491. You get factory geometry with better bushings and joints, plus less time on the press.

Best GX460 lower control arms (KDSS trucks)

The lower arm carries the spring and shock load, and on a lifted GX it decides how much alignment range you have left. Lift a GX far enough, or run a wider wheel with less offset for 35s, and the factory adjusters can run out. The truck comes back from the alignment rack with camber still off and a tech telling you "that's as far as it goes."

Adjustable lowers fix that. Here are the Lexus GX460 performance lower control arms we carry. Both are built for KDSS trucks.

SuperPro TRC494 KDSS offset lower arm kit, camber and caster adjustable (2010-2023)

The SuperPro TRC494 KDSS Offset Lower Arm Kit is the "give me all the range" option. It's an offset lower arm with both camber and caster adjustment, so your alignment tech can move both angles from the bottom of the suspension.

That's a big deal on a lifted GX where caster tends to drop. Fixing it from the lower arm means you aren't relying on the upper arm alone. It's listed for 2010-2023 KDSS trucks.

SuperPro TRC493 KDSS front lower control arm set, camber adjustable (2010-2023)

The SuperPro TRC493 KDSS Front Lower Control Arm Set is a complete control arm and ball joint assembly with camber adjustment. It's the simpler of the two. It's ideal if caster is already handled up top and camber is what's left to fix.

It also makes sense for a high-mileage KDSS truck that needs new lowers and a little extra camber range. Also listed for 2010-2023 KDSS trucks.

Our pick for GX460 lower control arms

On a lifted KDSS GX, we'd run the TRC494. Camber and caster adjustment at the lower arm gives your alignment tech the most room to work. Go TRC493 if you've already got corrected uppers and only need camber, or if you're refreshing worn lowers on a mildly built truck.

GX460 control arms compared

Here's every arm we carry for the GX460, side by side:

Bilstein vs SuperPro on the GX460

This one comes down to what you want from the front end.

Bilstein B8 makes sense if: you're on a 2010-2021, you're running Bilstein shocks or coilovers already, and you want a chromoly tubular upper with greasable bushings and replaceable parts. It's the arm we'd pick for a lifted truck that sees trails, washboard and highway.

SuperPro makes sense if: you want one maker for the whole front end, you're on a 2022-2023, or you want a fixed offset upper with nothing to adjust. SuperPro is also the only brand here with lowers for this truck. It's also the only one with an OEM-style refresh kit (the TRC491 for 2010).

Mixing is fine. A Bilstein B8 upper with a SuperPro TRC494 lower is a strong combo on a lifted 2010-2021 KDSS truck. The Bilstein corrects the upper geometry, and the SuperPro lower gives you extra adjustment at the bottom.

When do you actually need aftermarket arms on a GX460?

Stock height, tight front end, alignment in spec? You don't need lift arms. If the factory arms are worn, replace them with OEM-style parts and move on.

Here's when you need aftermarket arms:

• The truck is lifted and caster or camber won't come back to spec.
• The upper ball joint is binding or the upper arm hits the spring or coilover at full droop.
• It wanders on the highway after a lift. Low caster is the usual culprit.
• You're going bigger on tires. Stock rubber is 265/60R18, about 30.5 inches tall. Going to 35s usually means lifting, trimming and correcting geometry. Our 35s on a Lexus GX460 fitment guide walks through it.
• The bushings or ball joints are shot on a high-mileage truck. That's a refresh job, and the TRC491 (2010) or TRC493 (KDSS) handles it.

What about lowered GXs? It's rare on a body-on-frame truck with 6,500 lbs of towing capacity. If you've dropped one, the same thing applies. Once the factory arms run out of range, you need adjustable lowers to get camber back.

How much alignment range do you get?

Each arm fixes a different angle:

• Bilstein B8 uppers: designed to correct caster on a lifted truck, with better pivot angles for travel.
• SuperPro TRC6480 uppers: fixed offset built in. No adjuster, nothing to slip.
• SuperPro TRC491 uppers: standard (factory) alignment. Meant for stock height.
• SuperPro TRC494 lowers: camber and caster adjustable.
• SuperPro TRC493 lowers: camber adjustable.

Every one of these needs an alignment after install. Don't skip it. A truck this heavy with toe out of spec eats tires fast.

Ball joint vs uniball on a GX460

A uniball is a spherical bearing that replaces the ball joint. It allows more angle, which is why desert and rock builds love it. The trade-off is more inspection and service, and it can get noisy once grit gets in.

Every arm we carry for the GX460 uses a ball joint. Bilstein uses heavy-duty ball joints on the B8. SuperPro uses redesigned, uprated joints on the TRC491, and the TRC493 is a full control arm and ball joint assembly.

For a GX that's a daily, a tow rig or an overlander, we'd run a ball joint every time. It's quieter, it needs less service, and it holds up fine with the angle corrected.

Do aftermarket arms make noise?

Poly bushings ride a little firmer than rubber and can squeak if they dry out. That's why greasable bushings matter. The Bilstein B8 lets you grease the bushings, so a squeak gets a shot of grease instead of a teardown.

SuperPro builds its whole range around its own poly bushings, and on the TRC491 they come pre-fitted in the arm. Most clunks after an install come from hardware that was torqued with the suspension hanging. Torque the bushing bolts with the truck at ride height and most "new arm noise" goes away.

How long does install take?

Upper arms are the easier job. Support the truck, pull the wheel, unbolt the upper ball joint from the knuckle and the arm from the frame, swap, reassemble. A decent home mechanic with a floor jack, stands and a torque wrench can knock out a pair in an afternoon. A shop is quicker.

Lowers are more work because the lower arm carries the spring and shock load and sits near the KDSS hardware. If you aren't comfortable working around loaded suspension, let a shop do it. In both cases, book the alignment for right after the install.

While the wheels are off, think about the rest of the corner. Bigger tires add weight and rotating mass to a truck that already weighs 5,130 lbs or more at the curb. Our Brembo vs Wilwood breakdown is worth a read before you go up in tire size. If you're picking new wheels too, the GX runs 6x139.7 with a 106.1 mm hub bore and M12 x 1.5 lugs. Cast vs forged wheels covers what's worth spending on. Measure before you buy, the same way we did in our Ford Maverick wheel fitment guide.

What we'd do

Lifted 2010-2021 KDSS GX: Bilstein B8 51-304690 uppers plus SuperPro TRC494 lowers. That's caster correction up top and full adjustment down low.

Lifted 2022-2023 KDSS GX: SuperPro TRC6480 uppers plus SuperPro TRC494 lowers. One brand, fixed uppers, adjustable lowers.

Mild lift that just needs caster back: uppers only (B8 or TRC6480). Add lowers only if the alignment still won't come in.

Stock 2010 with worn uppers: SuperPro TRC491. Done.

GX460 control arm FAQ

Do I need upper control arms on a lifted GX460?

On most lifts, yes. Raising the front steepens the upper arm, which drops caster and pushes the upper ball joint toward the end of its travel. You'll feel it as highway wander and see it as an alignment that won't hit spec. The Bilstein B8 (2010-2021) and SuperPro TRC6480 (2010-2023) both fix that geometry. Mild setups can sometimes get by, but the GX's 52 percent front weight bias is hard on a ball joint running at a steep angle.

What are the best GX460 lower control arms?

For a lifted KDSS truck, the SuperPro TRC494 is our pick because it adjusts both camber and caster. The SuperPro TRC493 adjusts camber only and comes as a complete control arm and ball joint assembly. Both are listed for 2010-2023 KDSS trucks. Pick the TRC494 if you need the most range and the TRC493 if camber is the only angle left to fix.

Are there OEM-style upper control arms for the Lexus GX460?

For the 2010 GX460, yes: the SuperPro TRC491. It's two complete OEM-style upper arms with pre-installed SuperPro bushings and uprated ball joints in a standard alignment setup. It bolts in like the factory part. It's a stock-height refresh, not a lift arm.

Does the Bilstein B8 upper arm fit a 2022 or 2023 GX460?

No. The Bilstein B8 51-304690 is listed for the 2010-2021 GX460. For 2022 and 2023, including the Black Line Special Edition, go with the SuperPro TRC6480 fixed offset uppers, which cover 2010-2023. Same job, different design: fixed offset instead of Bilstein's tubular chromoly build.

Do these lower control arms fit a GX460 without KDSS?

Both lower arm kits we carry, the TRC494 and TRC493, are built for KDSS trucks. KDSS was standard on the 2014 GX 460. If you're unsure what your truck has, send us your VIN before ordering and we'll confirm. Don't guess on this one, because the wrong lower arm is a wasted weekend.

Do I need new arms for 35s on a GX460?

Usually, yes. Stock tires are 265/60R18, roughly 30.5 inches tall, so 35s are a big jump. Getting there generally takes a lift, some trimming and corrected front geometry. Upper arms are almost always part of it, and adjustable lowers help if the alignment runs out of range. Our 35s fitment guide covers the full build.

Can I mix Bilstein uppers with SuperPro lowers?

Yes, and on a lifted 2010-2021 KDSS GX it's a combo we like. The Bilstein B8 corrects caster and improves upper pivot angles. The SuperPro TRC494 adds camber and caster adjustment at the lower arm. Get an alignment once both are installed so the angles are set as a system.

Are poly bushings noisy on a GX460?

They can squeak if they run dry, which is why greasable bushings like the ones on the Bilstein B8 are a plus. A shot of grease at service time keeps them quiet. Most clunks after an install come from bolts torqued with the suspension hanging. Tighten bushing hardware at ride height and you'll avoid most of the noise.

Do I need an alignment after installing control arms?

Every time, no exceptions. New arms change camber, caster and toe, even OEM-style ones like the TRC491. On a truck with a 5,130-lb or heavier curb weight, a bad toe setting will wear the edges off a set of tires in a hurry. Book the alignment for right after the install.

Does the GX460 Luxury need different front control arms?

The front suspension is double wishbone with coil springs across the range. The Luxury's differences are in the rear (air instead of coils) and its AVS adaptive dampers. Order by year and KDSS, using the fitment listed on each arm. If you're unsure about your build, send us the VIN.
