Spec Clutch SJ252 Stage 2 Clutch Kit with Kevlar Disc and Pressure Plate

The Spec Clutch SJ252 Stage 2 Clutch Kit is engineered for mild to moderately modified naturally aspirated and power adder engines. It also excels at stock power levels where maximum daily drivability and exceptional service life are the priority. The Stage 2 delivers stock-like engagement feel with a notable step up in torque capacity and wear resistance compared to a Stage 1 setup.

At the core of the Stage 2 is a segmented or full-faced pure Kevlar friction disc with a steel backing — a material chosen for its outstanding drivability characteristics and long service life. The high-clamp pressure plate increases clamping load over stock to handle higher torque demands, while the high-torque sprung hub and disc assembly absorbs driveline shock and smooths engagement. The double-sprung hub features spring cover reliefs for added flexibility, and all hub components are heat treated for strength and durability.
