Rear Subframe Raising Bushings

The GK Tech Polyurethane Rear Subframe Bushing Kit offers a significant upgrade over stock components by minimizing subframe movement for enhanced vehicle dynamics. Constructed from ShA 80 Polyurethane, these stiffer bushings deliver a more solid rear end, directly translating to improved driver control and a more connected feel to the road. A key advantage of this kit is its ability to raise the subframe by 10mm. This modification is crucial for correcting the roll center on lowered vehicles, optimizing suspension geometry and improving handling characteristics. Installation involves removing the old bushings and pressing in the new polyurethane units. While the source material notes that some users found instructions slightly vague, GK Tech provides install videos and assembly guides to aid the process. The denser material is expected to cause a slight increase in cabin noise and vibration, but this is generally considered negligible by enthusiasts who have likely already adopted other modifications like coilovers or aftermarket exhausts. This bushing kit is compatible with a wide range of Nissan vehicles, including the Skyline R32, R33, and R34 (GTR/GTS-4 models may require separately available shims), as well as the A31 Cefiro, and S13, S14, and S15 240SX/Silvia models. These are designed as direct replacements for the OEM bushings, ensuring a precise fit and function.
