Torque Converter FastLap GM TH350 Circle Track

The Torque Converter FastLap GM TH350 Circle Track is specifically designed for oval-track racing and high-demand circle track competition, where consistent power delivery and precise stall characteristics are essential. This converter is tailored for General Motors TH350 transmissions, addressing the unique challenges of sustained cornering loads and repeated acceleration cycles typical in short-track and dirt racing environments.

Engineered for durability, the FastLap series features a precisely calibrated stall speed that optimizes the TH350's power band engagement, minimizing parasitic fluid loss and maximizing torque multiplication during launches and mid-corner acceleration. The internal construction includes billet components and reinforced welds, designed to withstand the shock loads generated by rapid direction changes and sustained throttle inputs in oval-track racing.

Circle track racers, whether running naturally aspirated or lightly boosted setups, will benefit from the FastLap's emphasis on durability and repeatability. This converter ensures consistent performance lap after lap, eliminating the unpredictability that can cost races due to converter slippage or heat creep during extended green-flag runs.
