Show original supplier description
The GKtech Z33X-DIFF solid differential bushes are constructed from durable 6061-T6 aluminum, providing a direct replacement for OEM components. Their primary function is to significantly reduce differential movement within the subframe, a common issue experienced under high-performance driving conditions like drifting or hard acceleration. This enhanced stability helps to minimize wheel hop. These solid bushings also feature a 12mm riser, which is particularly beneficial for lowered vehicles. By raising the differential, they help to correct axle geometry, reducing the angle of the axles and mitigating stress on CV joints that can occur at extreme angles. Installation is straightforward and requires no modifications. The front bushes can be installed by hand into the differential, and the rear bush is pressed into the subframe. While OEM nuts and bolts can be reused, some users recommend using specialized tools for easier installation, particularly for the rear bush on raised versions. The product is compatible with Nissan Z33 350z (2003-2008) and Infiniti G35 (V35) models (Coupe 2003-2007, Sedan 2003-2006). Note that the 2007-2008 G35 (V35) Sedan uses Z34 370z/G37 (V36) suspension. It's important to note that the GKtech diff brace is not compatible with these raised bushings; it can only be used with OEM bushings.
