Improve front-end stability, steering response, and cornering control with the SuperPro SPF4207K front lower control arm caster bushing kit. Designed for select Mazda CX-5 and Mazda6 applications, these offset polyurethane bushings add positive caster to the front suspension geometry. The result is improved straight-line tracking, stronger return-to-center action, and more consistent steering behavior with less driver correction.
The additional caster also promotes dynamic camber gain as the steering angle increases. During cornering, the front tires can maintain more of their contact patches against the road as the suspension loads, helping resist tire roll onto the shoulder and supporting more predictable grip. The caster change slightly increases steering weight away from center, providing enhanced steering feel and better feedback near the handling limit without negatively affecting tire wear, ride comfort, or everyday drivability.
SuperPro manufactures the SPF4207K using its proprietary engineering-grade polyurethane compound, developed through decades of suspension expertise and testing in demanding Australian conditions. Compared with conventional rubber bushings, this material is designed to resist degradation from extreme temperatures, oils, water, and coolant while maintaining dependable performance. The bushings preserve OEM-like noise and harshness isolation while improving suspension response, durability, and road manners in a wide range of driving conditions. Designed, engineered, and manufactured in Australia, this kit is backed by SuperPro's lifetime warranty. Verify vehicle configuration before ordering.
