Our unique billet main girdle for the 2003-06 Nissan 350Z and Infiniti G35 is an integral part of any high power motor build. This is the same girdle used in our 1,000+ whp drag motor and has provided the necessary strength and rigidity for many other high horsepower builds. Formed from CNC billet aluminum, the girdle forms a truss to connect all five journals.

This main girdle also allows for the VQ35DE to be stroked to 88mm, which is very helpful along with any Brian Crower stroker kit. Otherwise, the stock girdle must be notched. This is also compatible with OEM-length main studs, such as the ARP main studs.

Injected Performance produces and assembles high quality items based on first-hand knowledge, experience, and track-tested results. Although our specialty lies in Nissan VQ35-related engine components, we have made high quality goods for many other markets as well, utilizing principles learned through our diverse experiences. Whether it is an item manufactured in-house, assembled from unique knowledge, or packaged in an innovative fashion, Injected Performance components should be at the top of your list.
