Prothane 14-306 Rear Control Arm Bushing Kit Polyurethane 95-98 Nissan 240SX S14

The Prothane 14-306 is a polyurethane rear control arm bushing kit designed as a direct replacement for the factory rubber bushings on the 1995–1998 Nissan 240SX (S14 chassis). Worn or degraded OEM rubber bushings allow the rear control arms to shift under load, leading to inconsistent alignment, uneven tire wear, and unpredictable handling. Replacing them with Prothane's polyurethane bushings restores proper suspension geometry and helps maintain accurate alignment settings.

Key Features:

• Precision-molded polyurethane construction — firmer than OEM rubber for improved compliance resistance and sharper handling response
• Resists road salts, grime, oils, and other environmental contaminants that degrade rubber over time
• Helps maintain consistent rear camber and alignment settings under hard cornering and everyday driving
• Available in red or black — both colors share the same durometer hardness and performance characteristics
• Black bushings include a small amount of graphite in the polyurethane formula as an additional anti-squeak measure
• Includes Prothane Super Grease — proper lubrication at installation is essential to prevent squeaking
• Made in the USA
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship for the life of original ownership

Installation requires pressing out the original bushings and pressing in the new polyurethane units. Thorough application of the included Super Grease at install is critical to long-term, squeak-free performance. The Prothane 14-306 is an ideal upgrade for street-driven, autocross, or track-use 240SX builds where rear suspension precision is a priority.
