The 15068 is designed to solve the geometry limitations of the factory Metric front end. While stock arms are prone to flexing and offer limited alignment adjustment, the JOES Metric arm is built with the "lead" and angles necessary to achieve the high-caster, high-camber settings required for circle track racing.
Detailed Technical Specifications
1. Metric-Specific Geometry
-
G-Body Direct Fit: Specifically dimensioned to bolt onto the narrow mounting points of the 1978–1988 GM Metric chassis without modification.
-
Alignment Optimization: Engineered to provide better "gain" throughout the suspension travel, helping the front tires stay flatter on the track surface during heavy body roll.
2. Rugged Steel Shaft & Bushing Pivot
-
High-Strength Steel Shaft: The steel pivot shaft provides maximum resistance to bending during wheel-to-wheel contact or heavy curb strikes—a common occurrence in Stock and Limited classes.
-
Performance Bushings: Designed to meet the rules of racing series that require non-bearing pivots. These bushings provide a significant reduction in deflection compared to soft OEM rubber, ensuring the arm stays indexed under load.
-
Reliability in Dirty Environments: The bushing-style design is highly resistant to the grit, mud, and dust found on dirt tracks, requiring less maintenance than more delicate bearing systems.
3. Professional Race Fabrication
-
Structural Integrity: Constructed from high-grade steel tubing that eliminates the "give" associated with factory stamped arms, providing a more direct steering response and more predictable handling.
-
Precision Manufacturing: Fixture-welded to ensure that every arm is perfectly square and consistent, allowing for repeatable chassis setups.
