SPL Parts Rear Traction Links
2020–2023 Toyota GR Supra & 2019+ BMW Z4
SPL RTR G29
Overview:
The SPL Parts Rear Traction Links are precision-engineered suspension components designed to enhance the rear-end stability and responsiveness of the Toyota GR Supra (2020–2023) and BMW Z4 (2019+). By eliminating bushing deflection during hard acceleration and braking, these adjustable traction arms significantly reduce wheel hop on aggressive launches, delivering improved traction and control. Ideal for high-performance street and race vehicles, these links allow enthusiasts and racers to fine-tune rear bumpsteer and anti-squat characteristics for optimized handling dynamics.
Whether you’re pushing your Supra or Z4 on the track or seeking sharper response on the street, SPL Parts Rear Traction Links provide a direct, durable connection that elevates your vehicle’s suspension performance.
Key Features:
Engineered for precision and durability, the SPL Rear Traction Links offer a range of advanced features:
- Length adjustable design for precise tuning of rear bumpsteer and anti-squat settings
- Gun drilled 2024 aluminum center links, clamps, and clevises for lightweight strength
- Blue anodized titanium socket head cap screws for corrosion resistance and durability
- 360-degree rotating clamp system for easy and accurate alignment adjustments
- FK Bearings rod ends with Teflon-lined PTFE inserts for smooth articulation and low friction
- Elimination of bushing deflection under load to improve stability during acceleration and braking
- High load carrying capacity and excellent wear resistance with operating temperatures from -65Âş to 325ÂşF
- Simple locking mechanism using a 3/16" Allen key for hassle-free adjustment without disturbing bearing orientation
- Made in the USA with meticulous engineering and assembly standards
Construction & Design:
SPL Parts utilizes premium materials and advanced manufacturing techniques to build these rear traction links. The core components are crafted from 2024 aluminum, known for its exceptional strength-to-weight ratio, and are gun drilled to reduce weight without sacrificing rigidity. The clamps and clevises are precision machined to ensure a perfect fit and reliable performance under demanding conditions.
Fasteners are made from titanium and anodized blue to resist corrosion and maintain a clean, professional appearance. The innovative 360-degree rotating clamp system simplifies installation and adjustment, allowing for quick and precise tuning without the need for complex tools or procedures.
At the heart of the linkage are FK Bearings rod ends, manufactured in Connecticut, featuring a chemically bonded PTFE liner that provides quiet operation, low friction, and smooth articulation. This design eliminates the common issue of bushing deflection, ensuring consistent and predictable suspension behavior.
Installation & Fitment:
These rear traction links are designed as direct replacements for the factory components on the Toyota GR Supra (2020–2023) and BMW Z4 (2019+). Installation requires standard hand tools and can be completed by experienced enthusiasts or professional mechanics. The adjustable length feature allows for fine-tuning of suspension geometry without the need for additional modifications.
Thanks to the 360-degree rotating clamp system and simple locking mechanism, alignment settings can be secured quickly using only a 3/16" Allen key, eliminating the need to hold bearings in place during tightening. This user-friendly design reduces installation time and improves accuracy.
