FTI Performance

FTI Performance brings decades of drag-racing and street-performance expertise to every transmission component. The collection covers high-stall torque converters, reinforced automatic transmissions, valve bodies, flexplates, and rebuild parts built to handle big power and hard launches.

Each piece is engineered for repeatable shift quality, heat management, and long service life—whether you're cutting a reaction time or towing heavy. Expect tight tolerances, furnace-brazed fins, and upgraded friction materials across the lineup. This is hardware that prioritises consistency and durability, from bracket racing to weekend cruising.
