Eliminate slop and restore precision to your rear suspension with the GKTech Polyurethane Rear Knuckle Bushings (PURR-KKBH), available in Canada from Straight Six Imports.

These high-performance polyurethane bushes are a direct, durable replacement for the soft OEM rubber bushings in the rear knuckle's upper arm position. By installing these, you significantly reduce deflection and movement, leading to sharper handling, more predictable rear-end behavior, and a direct connection between your chassis and the road.

Why Upgrade to GKTech Polyurethane?

• Improved Suspension Geometry: Reduces unwanted flex, maintaining proper camber and traction arm alignment under hard cornering, drifting, and acceleration.

• HICAS Ball Joint Conversion: These bushings are required when converting a HICAS-equipped rear knuckle to a standard setup by removing the ball joint.

• Direct OEM Replacement: Designed to replace the OEM upper arm bushings on the knuckle side for various Nissan S and R chassis vehicles.

• Durable Polyurethane: Far superior to factory rubber, offering a long-lasting solution for your track or aggressive street build.
