Product Description

The Superpro SPF4427K Front Differential Mount Bush Kit is designed as a direct upgrade and replacement for the worn rubber bushings that connect the front differential to the frame on Jeep Grand Cherokee models from 2005 through 2010. The original rubber bushes can flex excessively under load, allowing unwanted drivetrain movement during acceleration and braking. This Superpro kit uses durable polyurethane to firm up the differential mounts, improving responsiveness, reducing wheel hop, and enhancing front-end stability for everyday driving or off-road use.

Constructed with high-quality materials and backed by a lifetime manufacturer warranty, the SPF4427K kit delivers longer service life and greater resistance to oil, water, and environmental wear compared to the stock bushings. These benefits contribute to improved handling characteristics and a more connected driving feel, especially on lifted or heavily loaded vehicles. Installation is straightforward with basic tools, and a follow-up drivetrain check is recommended after fitment. Always verify fitment with your VIN or manufacturer reference before installation.
