The 15015 is designed for the serious racer who understands that "suspension travel" should only happen at the spring and shock, not at the pivot point. Rubber bushings compress under load, leading to unwanted changes in camber and caster mid-corner. The JOES steel bushing provides a rock-solid interface, ensuring that every movement of the control arm is precise and predictable, leading to better "turn-in" and more consistent lap times.
Detailed Technical Specifications
1. Zero-Deflection Engineering
-
Rigid Pivot Point: By using a steel-on-steel (or steel-on-sleeve) interface, this bushing eliminates the "binding" and "squish" found in non-metallic bushings.
-
Maintains Alignment: Ensures that the settings you choose on the setup blocks remain the same when the car is pulling high G-loads on the track.
-
Low Friction Design: Precision-machined surfaces allow the A-arm to swing freely through its vertical travel without the mechanical resistance often found in dry polyurethane.
2. Heavy-Duty Durability
-
Wear-Resistant Alloy: Built to withstand the constant oscillation and high-impact loads of short-track racing.
-
Heat Tolerance: Unlike rubber, which can soften and fail near high-temperature brake systems, these steel bushings remain structurally sound regardless of ambient heat.
-
Corrosion Protection: Finished to resist the harsh environment of racing, including moisture, brake fluid, and track-cleaning chemicals.
3. Fitment & Installation
-
Standard A-Arm Compatibility: Designed to fit into standard steel control arm housings common in Circle Track and Street Stock racing.
-
Press-Fit Security: Engineered for a tight interference fit to ensure the bushing stays indexed within the arm during extreme use.
