Prothane 13-302-BL Rear Control Arm Bushing Kit Upper & Lower Black

The Prothane 13-302-BL is a polyurethane rear control arm bushing kit designed as a direct, performance-oriented replacement for worn factory rubber bushings. This kit covers both the upper and lower rear control arms and is finished in black.

Factory rubber bushings flex and degrade over time, allowing control arms to shift under load and throwing suspension geometry out of spec. Prothane's polyurethane formulation provides significantly greater compliance resistance than OEM rubber, helping to maintain consistent alignment settings and delivering more precise, predictable handling.

Key Features:

• Polyurethane construction — firmer than OEM rubber for improved handling response
• Covers upper and lower rear control arm positions
• Black finish with graphite blended into the polyurethane to help reduce noise and squeaking
• Same durometer hardness as Prothane red bushings — color is a matter of preference, not performance
• Includes Prothane Super Grease pre-lube for proper installation lubrication
• Backed by Prothane's lifetime warranty against defects in materials and workmanship for the original purchaser

For best results and to prevent squeaking, thoroughly lubricate each bushing with the supplied grease during installation. This kit is part of Prothane's broad Eclipse suspension lineup and is also referenced as part number 13-302.
