SPL Rear Upper Arms & Rear Traction Links – Toyota Supra A90 GR / BMW G2X / BMW G42

Maximize Performance with Precision Adjustability
The SPL Parts TITANIUM Series Rear Upper Arms (RUA) and Rear Traction Links (RTR) offer an expanded range of rear camber and traction adjustments, making them essential for high-performance track and street applications. Lowered vehicles often struggle to achieve proper camber settings with the limited adjustment provided by the OEM control arm's eccentric washer—our components solve this issue with precision engineering.

Rear Upper Arms (RUA)

Superior Construction & Innovation
Crafted for strength, performance, and ease of use, our Rear Upper Links feature:

• Gun-drilled 2024 Aluminum center links, clamps, and clevises for reduced weight and increased rigidity.

• Blue Anodized Titanium Socket Head Cap Screws for durability and a sleek aesthetic.

• 360° Rotating Clamp System that allows for quick and effortless adjustments using a simple 3/16" Allen key—no more struggling with jam nuts while maintaining proper bearing orientation.

Advanced FK Spherical Rod Ends for Maximum Stability
Stock links with soft rubber bushings allow unwanted suspension deflection under heavy loads. Our FK Spherical Rod Ends eliminate this issue by offering:

• A Teflon-lined design for reduced friction and smooth articulation.

• Enhanced durability with a PTFE liner that resists wear and operates reliably in temperatures ranging from -65ºF to 325ºF.

• Improved handling and stability by preventing unwanted alignment shifts during cornering, acceleration, and braking.

Complete Rear Upper Arm Kit
Each kit includes two pairs of adjustable rear upper arms:

• Rear Upper Lateral Arms

• Rear Upper Trailing Arms

Rear Traction Links (RTR)

Enhanced Stability & Response
SPL Parts TITANIUM Series Rear Traction Links (RTR) are designed to increase stability and response by eliminating bushing deflection under hard acceleration and braking, reducing wheel hop on aggressive launches. Our length-adjustable links allow fine-tuning of rear bump steer and anti-squat characteristics, making them ideal for high-performance street and race vehicles.
