Description

The SPL rear knuckle bushings replace the rubber factory knuckle bushing with a low friction PTFE-lined spherical bearing. Replacing the OEM rubber bushing eliminates deflection under heavy acceleration and braking loads that leads to unwanted geometry changes, and prevents binding by allowing the knuckle to smoothly articulate. The reduced deflection also translates to improved driver feedback from the tire and better overall response. We use the largest possible FK bearing, to increase longevity and reduce NVH, mounted in a 6061-T6 aluminum housing precision cut with +/- .001" tolerance to insure proper fitment. Benefits Lightweight: 0.674 lbs (306g) / 0.337 lbs (153g) per Side Improves Throttle and Braking Response Reduced Wheel Hop Maintenance-Free, US Made, PTFE-Lined FK Bearings Materials 6061-T6 Aluminum Bearing Shells Steel PTFE-lined FK Spherical Bearings

Product Overview

The SPL RKB FRS replaces the squishy rubber bushing located in the rear knuckle where the traction arm connects with a solid FK spherical bushing. The FK bearing is US-made, PTFE-lined, and eliminates bushing deflection during braking and acceleration, providing better tire feel and sharper response, while also reducing suspension bind. Sold as a pair. Made in the USA
