This 8.5" arm is designed to replace the weak, stamped-steel factory arms that were never intended for the high-stress environment of racing. By utilizing a fixed length and a rigid steel construction, JOES ensures that your front-end geometry stays consistent, preventing the "handling fade" that occurs when stock components flex or deflect mid-corner.
Detailed Technical Specifications
1. Metric Clip Specific Geometry
-
8.5" Precision Length: Sized specifically to achieve the desired camber gain and roll-center heights on the Left Front of a Metric-chassis race car.
-
Direct Bolt-In Replacement: Designed to mount to the standard Metric frame brackets, allowing for a professional suspension upgrade without the need for extensive chassis fabrication.
2. Bolt-In Ball Joint Compatibility
-
3-Bolt Metric Pattern: Specifically designed for the small GM Metric bolt-in ball joint (K5208 style). This makes ball joint replacement fast and simple, requiring only basic hand tools rather than a hydraulic press.
-
Reinforced Mounting Plate: The ball joint plate is CNC-cut and reinforced to prevent "rocking" or ovaling of the bolt holes under high lateral G-loads.
3. High-Strength Construction
-
Steel Tubing Integrity: Constructed from high-quality steel tubing that offers a superior strength-to-weight ratio compared to OEM arms.
-
Consistent Pivot Alignment: Features a rigid inner structure that prevents the arm from "bowing" under heavy braking or during aggressive corner entry.
-
Raw/Durable Finish: Typically provided in a finish that resists the harsh grit and chemicals found in dirt and asphalt racing environments.
