Flexplate 153T External Balance 86-up

The ALLSTAR PERFORMANCE Flexplate 153T External Balance is a heavy-duty flexplate engineered for small block Chevy engines running 1986 and newer, delivering reliable torque transfer between the engine and transmission. Designed with external balance characteristics, this 153-tooth steel flexplate is built to handle performance and street applications where precise crankshaft-to-torque-converter engagement is critical.

The 153-tooth design matches factory small block Chevy specifications, ensuring compatibility with OEM and performance torque converters calibrated for this tooth count. Steel construction provides the strength necessary to transmit high horsepower loads without flex or distortion. The one-piece seal design eliminates potential leak points that can occur with multi-piece alternatives, reducing maintenance concerns during extended operation. External balance means this flexplate is paired with external balance weights on the crankshaft and torque converter—correct balance is essential for smooth operation and minimal vibration at idle and under load.

This flexplate is ideal for small block Chevy engine swaps, restorations, and performance builds where original or period-correct drivetrain components are required. Street rods, classic truck builds, and performance engines demanding reliable torque delivery in the 1986-and-later platform benefit from this flexplate's proven design. Whether replacing a worn original or upgrading from a damaged unit, the ALLSTAR 153T addresses the precise mechanical requirements of external-balance small block Chevy applications without compromise.
