2.50 Inch 3 Bolt Flange

The 2.50 Inch 3 Bolt Flange from QUICK TIME PERFORMANCE is a critical engine-to-transmission coupling component designed for high-performance automotive builders and restoration specialists. This compact yet essential adapter bridges the gap between modern engine platforms and transmission bellhousings, enabling engine swaps, restorations, and custom drivetrain configurations that would otherwise be impossible. Whether you're installing a crate engine in a classic muscle car, adapting a late-model powerplant to vintage chassis, or building a custom hot rod, this three-bolt flange provides the precision interface your build demands.

Engineered from robust materials to handle torque loads and thermal cycling without deflection, the 2.50 inch diameter 3-bolt flange features a precisely machined three-bolt pattern that maintains strict tolerances for concentricity and runout. The compact 4.05 x 4.8 inch footprint allows it to fit tight engine bays while the minimal 0.48 lb weight contributes negligibly to your build's overall mass. The thin 0.45 inch profile ensures it won't interfere with adjacent components or create packaging headaches during installation, making it an elegant solution for space-constrained applications where every millimeter of clearance matters.

This flange is ideal for builders working with Quick Time Performance bellhousings and transmission adapters, particularly those engaged in fuel-injected engine conversions, LS swaps, small-block Chevrolet transplants, and vintage iron restoration projects. Professional mechanics and serious enthusiasts rely on QUICK TIME PERFORMANCE products for their dimensional accuracy and durability under sustained high-rpm operation. Proper installation requires careful centering on the engine block and precise bolt torque sequencing to ensure vibration damping and longevity; consult your engine and transmission documentation for specific torque specifications and alignment procedures.
