Nissan Rear Bushing Kit

The Nissan Rear Bushing Kit from PROTHANE is a precision polyurethane control arm bushing replacement engineered for the Infiniti G35 (2003–2007) and compatible Nissan platforms. As a vehicle ages, factory rubber bushings deteriorate, causing loose steering response, wandering on the highway, and increased suspension noise—issues every enthusiast and daily driver encounters. This rear lower control arm bushing kit restores chassis rigidity and handling feel that OEM components gradually lose over time, making it an essential upgrade for both restoration and performance-focused builds.

PROTHANE polyurethane bushings replace soft rubber with a durable elastomer compound that resists compression, oil degradation, and UV exposure far more effectively than OEM rubber. The red polyurethane material provides a natural compromise between ride comfort and geometric compliance—stiffer than factory rubber to eliminate slop, yet compliant enough to absorb road harshness without transmitting excessive vibration into the chassis. This chemistry allows the bushing to maintain consistent suspension geometry across dynamic driving conditions, preventing the progressive alignment loss that causes tire wear and unpredictable handling behavior. The kit's compact footprint (6.2 x 4.1 x 10.2 inches, 7.5 lbs) packages all necessary components for a complete rear lower control arm bushing installation.

Track enthusiasts, weekend mechanics, and owners pursuing tighter steering response benefit most from this bushing replacement, particularly on modified G35 platforms where suspension tuning demands precision. Professional installers and DIY builders often pair this kit with complementary suspension components—tie rod ends, sway bar links, and strut assemblies—to achieve a cohesive chassis refresh. Installation requires basic suspension knowledge, press tools, and jack support; OEM fasteners and mounting hardware are reusable, making this a cost-effective alternative to factory replacements that saves labor on subsequent maintenance cycles.
