Boss competition arms are upgraded with high durometer urethane bushings for greatly reduced deflection and upgraded longer ball joints for strength and improved front suspension geometry and alignment.
Reduced bushing deflection will noticeably increase steering response and maintain proper alignment geometry during hard cornering. The high-grade ball joints will improve front geometry for increased cornering grip, reduced under steer, and reduced body roll.
Most importantly, these arms won't fold up, bend and break under high load conditions like other aftermarket tubular designs.
Note:
Due to the relocation from the longer ball joint, 18 inch or larger wheels are required for clearance.
