Nissan Rack & Pinion Bushing Kit

The Nissan Rack & Pinion Bushing Kit from PROTHANE delivers a direct upgrade path for 2003–2009 Nissan 350Z owners seeking improved steering precision and reduced play. Rack and pinion bushings are wear items that degrade over time, allowing excess movement between the steering rack and subframe. This kit replaces the factory rubber components with polyurethane substitutes, restoring tight steering geometry and eliminating the mushy, unresponsive feel common in aging sports cars.

Constructed from red polyurethane material, these bushings offer superior durability and resistance to age-related cracking that affects original rubber components. Polyurethane maintains stiffness across temperature extremes and resists oil degradation, ensuring consistent steering input over thousands of miles. The material's rigidity significantly reduces rack deflection during aggressive cornering or load transfer, translating to more direct steering feedback and predictable handling characteristics. Installation is straightforward on the 350Z platform, with no modification required to existing subframe or suspension geometry.

Track-focused drivers, enthusiasts with high-mileage Z-cars, and anyone seeking tighter steering response will notice immediate improvements in on-center feel and cornering confidence. This kit is essential maintenance for 350Z models approaching 80,000+ miles where original bushings have typically fatigued. The compact kit (0.61 lbs) includes all necessary polyurethane components for complete rack bushing replacement, making it an efficient suspension upgrade that pairs well with other steering or chassis refinements.
