FTI Performance FTI-TH400-4.5UB Gm Th400 Level 4.5 Transmission

FTI Performance TH400 Level 4.5 transmissions begin with a race-prepped factory Chevy case—and end up rated up to 1,100 hp.

Each professionally hand-built case includes a short shaft, a billet aluminum drum and forward clutch hub, a 34-element sprague, and race material clutches.

An FTI billet aluminum trans-brake with a full manual reverse valve body is stout enough to handle major power and keeps reverse and first gears closely knit. The included deep aluminum pan allows more fluid capacity for increased cooling, while the 300M input shaft provides amazing strength. Whether you're racing off-road, on the street, or at the track, FTI Performance TH400 Level 4.5 transmissions fit the bill. Order the model best suited for your application.
