Prothane 14-304-BL Rear Lower Control Arm Bushings 1989-1994 Nissan 240SX

Prothane's 14-304-BL rear control arm bushings are a direct-fit polyurethane upgrade designed for the 1989–1994 Nissan 240SX. When factory rubber bushings wear out and allow excessive flex, steering response suffers and alignment settings become nearly impossible to maintain. Prothane's polyurethane formulation delivers the compliance resistance needed to keep the rear suspension geometry precisely where it belongs.

Key Features:

• Made from high-quality black polyurethane for superior durability over OEM rubber
• Engineered to maintain proper rear camber and caster alignment under load
• Resists compression and deflection caused by hard cornering and road forces
• Helps eliminate suspension slop and vague handling feel common with worn rubber bushings
• Direct replacement fit — no modification required for 1989–1994 Nissan 240SX
• Includes grease for proper installation and long service life

By upgrading to Prothane polyurethane, you can expect sharper steering feedback, more predictable handling, and alignment settings that stay true. The black finish blends cleanly with the undercarriage and resists UV degradation and chemical exposure common in the wheel well environment.
