Overview

The GK Tech polyurethane diff bushes are a direct replacement for standard items. Made from ShA 90 polyurethane, they minimize differential movement within the subframe, which is common under hard driving. Compared to solid variants, these offer a bit more give.
Show original supplier description
The GK Tech Z334-PUDF-BUNDLE includes polyurethane differential bushings designed as a direct replacement for OEM components. Constructed from ShA 90 polyurethane, these bushings are engineered to significantly reduce differential movement within the subframe, a common issue during spirited driving or performance applications. Installation is straightforward, requiring no modifications. The front bushes can be installed by hand into the differential, and the rear bush presses into the subframe. OEM nuts and bolts can be reused, and the bushes arrive as pictured. GK Tech offers specialized removal and installation tool kits (sold separately) that can facilitate the job even with the subframe on the vehicle, reducing installation time to approximately 30 minutes if the subframe is removed. While these polyurethane bushings are more rigid than stock, GK Tech notes that they do not cause a significant increase in cabin noise or vibration. This is often because vehicles that benefit from these upgrades typically already have other modifications like coilovers or aftermarket exhausts, which contribute to a noisier cabin environment. A note for some sedans indicates potential interference issues when using the installation tool due to the spare wheel provision.
