Crank Adapter Sleeve - GM LS to Early Trans.

The Crank Adapter Sleeve - GM LS to Early Trans. from PRW Industries is designed for builders adapting General Motors LS-series engines into vehicles originally equipped with earlier transmission platforms. This precision-engineered sleeve addresses the compatibility challenges that arise when integrating modern LS engines with older gearboxes, ensuring a reliable and efficient power transfer.

Manufactured by PRW Industries, this adapter sleeve is crafted to bridge the mechanical mismatch between the LS crankshaft flange and older gearbox input shafts. It is designed to maintain proper alignment and load distribution, which is critical for optimal crankshaft operation. The sleeve accommodates the dimensional differences between modern LS flange geometry and legacy transmission bell-housing bolt patterns.

This adapter is essential for automotive enthusiasts and professional builders undertaking LS platform swaps into vintage and early-model vehicles. It eliminates the need for costly custom fabrication or engine modifications, making it an ideal solution for restoring classic muscle cars or restomodding vintage platforms.
