LS To AR5 Transmission Adapter Kit

The LS To AR5 Transmission Adapter Kit by G FORCE CROSSMEMBERS solves one of the most common challenges in modern engine swaps and powertrain conversions: mating an LS-series engine to a Tremec AR5 transmission without custom fabrication. Whether you're building a hot rod, restoring a classic with contemporary power, or upgrading a performance vehicle, this adapter kit bridges the gap between two industry-standard components, eliminating guesswork and reducing installation time significantly.

Engineered to precise tolerances, the LS To AR5 Transmission Adapter Kit ensures proper bell housing alignment, bolt pattern compatibility, and pilot bearing concentricity—all critical factors for vibration-free operation and transmission longevity. G FORCE CROSSMEMBERS designs this adapter with CNC-machined accuracy and uses high-strength materials rated for the torque outputs typical of LS powerplants. The kit's compact design (12 x 4.5 x 12 inches) and lightweight construction (7.15 lbs) minimize added rotational mass while maintaining structural rigidity, making it ideal for street applications, autocross builds, and off-road conversions alike.

Mechanics and enthusiasts performing LS engine swaps across multiple platforms—classic Chevrolets, Camaros, Corvettes, and custom chassis—rely on this adapter to achieve OEM-quality results without expensive machine work. Installation is straightforward when following proper torque specifications and alignment procedures, making it accessible to both professional shops and experienced home builders. Verify your specific LS variant and AR5 transmission generation for optimal fitment, as some applications may require minor bracket modifications or crossmember fabrication.
