TREMEC GM Magnum XL 6-speed is here!

Like the original Magnum, the GM Magnum XL is an aftermarket version of the celebrated TR-6060, which serves as factory equipment in numerous Detroit-based muscle and sports cars. However in order to accommodate the rearward shifter location of modern performance vehicles, the XL’s unique extension housing moves the shifter over eight inches back from the original Magnum’s most rearward location. In addition, to keep NVH down to daily-driver acceptable levels, the XL is equipped with a unique shift isolator that provides an astonishing blend of dampening quality and precision shift feel. In the NVH (noise, harness and vibration)-sensitive world of modern automobile manufacturing, bolt-on ‘semi-remote’ shifters are often used on manual transmissions to isolate undesirable harmonics from the cabin of an otherwise quiet factory application. While they perform this function well, the trade-off is heavily compromised shift quality in high-performance or competitive driving environments. TREMEC’s GM Magnum XL 6-speed solves this problem with a unique extended-length tail housing that provides a rigid direct-mount shifter for vastly improved performance and lightning quick shifts.

This is a perfect upgrade if you have a 5th GEN Camaro, 1st GEN Cadillac CTS-V or a Pontiac GTO.
