Spacer Clutch Piston

The JERICO Spacer Clutch Piston (JER-0039) is a precision-engineered transmission component designed for high-performance applications requiring tight clutch control and optimal power transfer. Built to exacting specifications, this spacer piston manages engagement characteristics in heavy-duty drivetrain systems where conventional clutch geometry would result in slippage or delayed response under load.

Weighing 0.07 lbs and measuring 2.95 × 0.45 × 5.55 inches, the JER-0039 spacer piston is engineered to precise tolerances that directly impact clutch pack stacking geometry. The compact, lightweight design reduces rotational mass while maintaining structural integrity under extreme pressure cycling—a critical factor in drag racing, off-road, and marine transmission builds where clutch durability and consistent engagement are non-negotiable. The piston's dimensional profile works in concert with friction materials and pressure plates to establish the exact clearances needed for repeatable, firm engagement without harshness or chatter.

This component serves transmission rebuilders, performance shops, and powersports enthusiasts who demand maximum efficiency from high-horsepower builds. Whether upgrading a street/strip application, preparing an off-road or desert race rig, or restoring a vintage performance transmission, the JERICO spacer piston delivers the precision fit and repeatability that aftermarket transmission platforms require. Compatibility with JERICO transmission kits and assemblies makes this an essential wear item for those maintaining or upgrading their clutch pack configuration.
