ISR Performance Billet Transmission Mount Poly Bushing - Nissan 350z G35 Z33

The ISR Performance Billet Aluminum Transmission Mount with Poly Inserts is a direct upgrade over the factory rubber transmission mount on the Nissan 350Z and Infiniti G35. One-piece billet aluminum construction with poly inserts delivers a significantly stronger mount that resists the deflection and failure common to OEM rubber units.

What It Does

The factory rubber transmission mount on the Z33 chassis is designed for refinement, not durability. Under high-stress driving (track use, drift, autocross, or aggressive launches), the rubber compresses and deflects, which causes drivetrain shudder, sloppy shifts, and eventually outright failure of the mount. The ISR billet aluminum mount with poly inserts eliminates that deflection, giving you a solid mounting point that holds up to abuse while still using poly bushings to control vibration.
