Prothane 18-301 Red Rear Control & Trailing Arm Bushing Kit

The Prothane 18-301 is a red polyurethane rear control and trailing arm bushing kit engineered as a direct-fit, performance upgrade over factory rubber bushings. Prothane's premium-grade polyurethane compound is significantly firmer than OEM rubber, delivering improved compliance resistance that helps maintain precise alignment geometry and consistent handling characteristics.

Worn or deteriorated rubber control arm and trailing arm bushings allow excessive flex in the rear suspension, leading to vague steering response, accelerated tire wear, and shifting alignment settings. The Prothane 18-301 replaces these components with precision-molded polyurethane bushings that resist compression, torsion, and deflection under load.

Key Features:

• Premium-grade red polyurethane construction — firmer and more durable than OEM rubber
• Precision-fabricated for a direct-fit replacement with no modification required
• Splined or grooved bore retains included Prothane Super Grease for long-term, squeak-free operation
• Resists oils, solvents, road chemicals, and UV exposure
• Improves suspension compliance resistance for more consistent alignment retention
• Enhanced handling feel during cornering, braking, and acceleration
• Replaces rear control arm and trailing arm bushings as a complete kit

The Prothane 18-301 is part of Prothane's extensive Toyota-specific bushing lineup and is manufactured to meet the demands of both daily driving and off-road use. Installation hardware and Prothane Super Grease lubricant are included.
