Overview

The GK Tech Z33X-DBRC is a differential brace designed to provide additional support to the differential in your 350z or G35. It is constructed from solid steel sheet metal that is TIG welded and e-coated for rust prevention. The brace utilizes an existing hole in the subframe for a straightforward installation.

This brace helps reduce wheel hop under hard driving conditions by addressing the OEM diff cover's single bush and stud design, which is prone to wear and breakage. It offers a more sturdy design than some other aftermarket options, improving rear-end stability and reducing low-speed lurching.
Show original supplier description
The GK Tech Z33X-DBRC differential brace offers enhanced support for the differential in your Nissan 350z and Infiniti G35 (V35 chassis). By providing additional bracing, this kit significantly reduces wheel hop during spirited driving and can mitigate low-speed lurching. Constructed from solid steel sheet metal, the brace is TIG welded for robust joints and finished with an e-coat to ensure excellent rust prevention. Its compact and rigid design leverages an existing subframe hole, making installation remarkably simple—requiring only a couple of wrenches and about 15 minutes. The brace is compatible with Nismo diff covers without modification and can work with Z1 diff covers with minor modifications to the fins. However, it is not compatible with raised bushings. Crucially, this differential brace is not designed for vehicles equipped with a 4-wheel steering (4WS) system. Ensure your vehicle is not a 4WS model before purchasing. The installation is a direct bolt-on process with no permanent modifications required, making it a reversible upgrade.
