The SuperPro bushings are constructed from a durable polyurethane compound that resists cracking, tearing, and deformation under demanding driving conditions. The double offset design allows for precise adjustment of caster, which is critical for high-performance handling. The bushings are manufactured with tight tolerances and feature a one-piece construction that ensures a secure fit and long-lasting performance. Their design helps maintain proper suspension alignment and enhances overall vehicle stability, especially during spirited driving or high-speed cornering.

Installing these double offset bushings results in noticeable improvements in handling and steering feel. You will experience more direct and responsive steering, with better feedback from the road surface. The increased positive caster contributes to improved straight-line stability and more predictable turn-in.
