ISR Performance - Manual Transmission Crossmember - 350Z Z33

Our manual transmission crossmember for the 350Z. Solid 5/16" steel with 3/16" support gussets, black powder coated. Built for auto-to-manual conversions, replacing a damaged stamped factory unit, or any 350Z that's missing its original crossmember.

What It Does

Direct replacement for the factory stamped 350Z 6-speed manual transmission crossmember. The solid 5/16" steel construction with 3/16" support gussets is a real upgrade over the stamped OEM piece. It's stiffer, stronger, and built to handle the abuse that comes with aggressive driving and bigger power. Uses the factory transmission mount or our aftermarket IS-TMK-Z33 replacement mount.

Fitment

Fits Nissan 350Z (Z33) with the 6-speed manual transmission only. Not for the 5-speed automatic.
