Upgrade your GM TH400 automatic transmission with the Speedmaster PCE695.1001 Billet Aluminum Center Support. Machined from billet aluminum for superior strength and durability over stock components, this center support is engineered to handle the increased demands of performance and racing applications where the factory unit falls short.
Paired with a billet oversized intermediate piston, this kit helps deliver improved holding power and more consistent apply pressure within the TH400 transmission. Designed as a direct-fit replacement for GM TH400-equipped vehicles, it's an ideal upgrade for builders looking to reinforce the mid-section of their transmission for street performance or competition use.
