ISR Performance - Manual Transmission Crossmember - 350Z Z33

The ISR Performance manual transmission crossmember for the Nissan 350Z Z33 is a steel replacement for the factory 6 speed crossmember. It exists for three common situations: an automatic to manual conversion where no manual crossmember came with the car, a stamped OEM piece that has been bent or rusted, or an original that simply went missing during a build.

Why not reuse the automatic crossmember

The automatic and 6 speed transmissions in the Z33 sit differently, so the automatic crossmember does not line up with the manual mount. Rather than hunting for a used OEM piece, this ISR crossmember gives you a new, stronger part that accepts the OEM transmission mount or an aftermarket 350Z replacement mount such as the ISR IS-TMK-Z33.
