SPC Performance 01-05 Lexus IS300 Adjustable Upper Ball Joint (1.5deg.) - 67525

The SPC Performance Adjustable Upper Ball Joint (Part #67525) is a purpose-built camber correction solution designed specifically for the 2001–2005 Lexus IS300 — including both the Base sedan and the Sportcross wagon. Whether your IS300 has been lowered for performance driving or still rides at factory height, this sliding plate assembly restores proper geometry and tire contact patch by allowing up to ±1.5 degrees of camber adjustment. It's a direct upper ball joint replacement that brings OE-level build quality together with the real-world adjustability that stock components simply cannot offer.

Key Features & Benefits

• Designed Specifically for Lexus GS & IS: SPC engineered this ball joint with the chassis geometry of the Lexus IS300 in mind — not a universal adapter — meaning proper taper, thread pitch, and load ratings match what the factory intended.
• Up to ±1.5° Camber Correction: The sliding plate design lets you dial in camber within a meaningful range, correcting negative camber pull caused by lowering springs, coilovers, or worn factory geometry — and dialing it back when needed.
• OE Quality Replacement Ball Joint: This is not a compromise between adjustability and durability. The ball joint stud itself is built to OE-equivalent quality standards, so you're not sacrificing longevity for the ability to adjust.
• Sliding Plate Assembly: The sliding plate mechanism is what enables the camber adjustment range. It integrates cleanly with the factory upper control arm, so no additional fabrication or modifications to the arm are required.
• Works at Factory or Lowered Ride Heights: Unlike some camber correction parts that are only beneficial at aggressive drop, this ball joint is equally useful for IS300s at stock ride height that have developed camber issues over time through wear or minor suspension changes.
• Proposition 65 Compliant (CA residents notified): Product carries the appropriate California Proposition 65 warning — important for buyers in California to be aware of.

Frequently Asked Questions

Q: Does this ball joint work if my IS300 is still at stock ride height, or is it only for lowered cars?
A: It works for both. SPC specifically notes this sliding plate assembly is designed for vehicles that have been lowered for performance or retain the factory ride height. If your camber is out of spec due to wear or minor geometry changes, the ±1.5° adjustment range gives you the ability to correct it regardless of ride height.

Q: Does the SPC 67525 fit both the IS300 sedan and the IS300 Sportcross wagon?
A: Yes. Fitment covers the 2001–2005 Lexus IS300 Base sedan and the 2002–2005 Lexus IS300 Sportcross wagon. If you have any doubt about your specific build, reach out to our team with your VIN or trim details and we'll verify before you order.

Q: Does this replace my entire upper control arm, or just the ball joint?
A: The SPC 67525 is an upper ball joint replacement with an integrated sliding plate assembly. It replaces the ball joint and installs into your existing factory upper control arm — you do not need to replace the full arm.

Q: How much camber can I correct with this part?
A: The SPC 67525 provides up to ±1.5 degrees of camber adjustment. This is typically sufficient to correct the camber change introduced by most street lowering applications on the IS300 platform and to restore proper alignment specs.
