Allstar Performance is America's leading circle-track racing parts manufacturer. From aluminum panels and chassis components to brake hardware, steering boxes, and oval-track shock packages — every Allstar product is born from sprint car and modified racing experience.
Simplify your LS engine swap with the Allstar Performance ALL26121-20 Crank Adapter Sleeve. This kit is designed to allow the use of older GM torque converters with modern GM LS-series crankshafts. Because LS cranks have a different pilot hole diameter than traditional small block or big block Chevy engines, this adapter is a necessary component for any builder looking to retain an older transmission setup.
This adapter sleeve fits securely into the crankshaft, providing the correct pilot surface for your torque converter snout. By using this adapter, you avoid the need for expensive custom torque converters or transmission modifications, saving both time and money on your build. The black oxide coating provides excellent corrosion resistance, ensuring that the part remains in top condition for the life of the engine. Whether you are building a custom street rod, a track car, or a drag racer, this adapter is the professional solution for your transmission mating needs. Trust in the reliability of Allstar Performance for your engine swap requirements. Get your bulk performance parts and more at GGCRACING.
