Construction & Design:

Prothane’s Total Urethane Bushing Kit is engineered from premium-grade polyurethane, a material known for its superior strength, flexibility, and resistance to degradation from oils, fuels, and road chemicals. Unlike traditional rubber bushings that soften and deteriorate over time, polyurethane maintains its shape and performance characteristics, providing consistent suspension control and longevity.

The kit’s components are precision-molded to exact OEM specifications, ensuring a perfect fit and easy installation. This attention to detail preserves suspension geometry and alignment, which is critical for maintaining optimal handling and tire wear. The urethane formulation also helps dampen unwanted vibrations and noise without compromising the firmness needed for performance driving.
