Prothane 14-304 Rear Control Arm Bushing Kit 1989-1994 Nissan 240SX

Prothane's 14-304 Rear Control Arm Bushing Kit is engineered for 1989–1994 Nissan 240SX owners who demand precision handling and long-lasting suspension performance. Over time, factory rubber bushings deteriorate, causing control arms to flex and shift under load — robbing your suspension of its ability to hold proper alignment settings.

Prothane addresses this with a high-durometer polyurethane compound that delivers superior compliance resistance compared to OEM rubber. The result is tighter, more predictable suspension geometry that stays true through hard cornering, acceleration, and braking. Once installed, your camber and caster settings hold their position lap after lap or mile after mile — no more wandering alignment caused by mushy, worn-out bushings.

Key Features:

• Made from Prothane's premium polyurethane — harder and more resilient than factory rubber
• Maintains accurate alignment settings by eliminating unwanted bushing deflection
• Resists oils, solvents, and road chemicals that degrade OEM rubber over time
• Precision-molded to fit the rear control arm pivot points on 1989–1994 Nissan 240SX
• Includes grease fitting provisions for long-term lubrication and reduced squeaking
• Direct OEM replacement — no modification required for installation

Whether you're building a dedicated track car or simply refreshing a high-mileage 240SX, the Prothane 14-304 bushing kit is a proven upgrade that sharpens response and extends the service life of your rear suspension components.
