TREMEC TUKT12021 Details

The TREMEC TUKT12021 T56 Magnum XL takes the legendary Magnum platform to the next level. Built with superior strength, lightning-fast precision shifting, and a modern extended-length tail housing, it delivers the perfect shifter position for 2005-up Ford Mustangs.

This Magnum XL completely eliminates the sloppy factory semi-remote shifter setup and replaces it with a rigid direct-mount design for dramatically improved shift feel, shorter throws, and razor-sharp engagement.

Complete “KT” Bolt-In Kit for Ford Modular V8s Engineered specifically for Coyote and Godzilla engines, this is a true drop-in upgrade. The kit includes an SFI-approved steel bellhousing, Mustang-specific crossmember, and OE-quality transmission mount — everything you need for a professional installation with zero fabrication.

Built for Serious Power

700 lb-ft torque capacity
Revs safely to 7,800 RPM
Double overdrive gearing (.80 / .63) for strong acceleration and relaxed highway cruising

Whether you're building a high-performance street car, weekend warrior, or track-day Mustang, the TUKT12021 Magnum XL delivers the perfect balance of brute strength and refined drivability.
