SPC Performance 04-20 Ford F-150 Lowered Front Adjustable Upper Control Arms - 35675

The SPC Performance 35675 Adjustable Upper Control Arms are purpose-built for 2004–2020 Ford F-150 trucks that have been lowered, giving you back the alignment adjustability that a dropped front end robs from the factory geometry. When a lowered F-150 rolls into the alignment bay, standard upper control arms simply can't reach the caster and camber specs the truck needs — SPC's adjustable design solves that problem directly, letting an alignment technician dial in proper angles and restore tire wear, handling stability, and steering feel.

Key Features & Benefits

• Designed for Lowered Applications: Standard OEM upper control arms lack the range of adjustment needed after a front-end drop. The SPC 35675 is engineered specifically for lowered F-150s so you can actually achieve a proper four-wheel alignment rather than settling for whatever the geometry allows.
• Adjustable Caster & Camber: Built-in adjustability means your alignment shop can set caster and camber to factory specification — or fine-tune them for your specific driving goals — without aftermarket shims or guesswork.
• Improved Tire Life: Correct alignment angles reduce uneven tire wear, a common and costly side effect of running a lowered truck on non-adjustable control arms.
• Better Handling & Straight-Line Stability: Proper caster settings contribute directly to steering returnability and high-speed stability, both of which can degrade when a lowered truck is stuck with misaligned geometry.
• SPC Performance Engineering: SPC Performance is a well-established name in alignment-enabling suspension components, with a product line focused on solving real-world geometry problems for modified vehicles.
• Bolt-On Fitment: Designed to replace the factory upper control arms on the applicable F-150 years, keeping installation straightforward for a qualified shop or experienced DIYer.

Fitment

The SPC Performance 35675 is designed to fit 2004–2020 Ford F-150 trucks equipped with a lowered front suspension. If your F-150 is running at stock ride height or has been lifted rather than lowered, this specific part may not be the correct choice — the adjustable range is calibrated around a lowered application. Always confirm your year, configuration, and ride height before ordering. If you have any doubt, reach out to the ThreePiece.us team for fitment verification before purchase.

Frequently Asked Questions

What years of Ford F-150 do these upper control arms fit?

The SPC Performance 35675 is designed to fit 2004 through 2020 Ford F-150 trucks. They are specifically intended for trucks that have had their front end lowered, so confirm your application before ordering.

Why do I need adjustable upper control arms when I lower my F-150?

Lowering the front of an F-150 changes the suspension geometry enough that the OEM upper control arms can no longer reach proper caster and camber specifications. Adjustable upper control arms like the SPC 35675 restore that range of adjustment so a proper alignment is actually possible, which protects your tires and maintains safe handling.

Will these work on a stock-height or lifted F-150?

The SPC 35675 is engineered for lowered applications. If your truck is at factory ride height or has been lifted, this part may not be the appropriate choice. Contact us and we can help you find the correct SPC or aftermarket control arm for your specific setup.
