Prothane 1-302 Rear Control Arm Polyurethane Bushing Kit

The Prothane 1-302 is a polyurethane rear control arm bushing kit designed to replace the factory rubber bushings on the Jeep Wrangler JK. Worn OE rubber bushings allow the control arms to shift under load, throwing off wheel alignment and causing sloppy, unpredictable handling. Prothane's polyurethane compound delivers a firmer, more precise connection that holds alignment settings longer and resists the wear and deterioration that degrades rubber over time.

Key Features:

• Complete rear control arm coverage — includes bushings for both upper and lower trailing arms, with two half-bushings and a metal inner sleeve at each position
• Polyurethane construction — firmer than OEM rubber for improved compliance resistance and more accurate alignment retention
• Resistant to heat, road salts, and oils — polyurethane does not degrade from exposure to the elements the way rubber does
• Available in red or black — both colors share the same durometer (hardness) and performance characteristics; black bushings include a small amount of graphite which may help reduce squeaking
• Includes Prothane Super Grease — proper lubrication at installation is essential to prevent squeaking and maximize bushing life
• Lifetime warranty — Prothane guarantees these bushings against defects in materials and workmanship for the life of the original purchaser's ownership

Installing the Prothane 1-302 kit eliminates the flex and deflection of tired rubber bushings, restoring proper rear suspension geometry and reducing uneven tire wear. Be sure to apply the included Super Grease thoroughly to each bushing during installation to ensure quiet, long-lasting performance on the street and trail.
