Spec Clutch SM583F Stage 3 Plus Performance Clutch Kit

The Spec Clutch SM583F Stage 3 Plus is the flagship performance clutch kit for heavily modified street and race engines that have exceeded the torque capacity of the standard Stage 3. Engineered for high-powered builds that demand serious torque handling with a more manageable pedal feel than traditional puck-style race clutches, the Stage 3+ delivers an ideal balance of aggressive performance and daily drivability.

At the heart of the Stage 3+ is a carbon semi-metallic full-faced friction disc — an upgrade over the 6-puck design of the Stage 3 — providing superior wear characteristics, an excellent friction coefficient, and long service life. The full-faced disc design reduces the harsh on/off engagement feel common with pure race clutches, making this kit a versatile choice for street driving and competition alike.

The double-sprung hub features spring cover reliefs for added flexibility, while heat-treated internal components ensure lasting strength and durability under extreme loads. Combined with a high-clamp pressure plate, this kit delivers the clamping force needed to handle high-torque applications without slipping.

• High-clamp pressure plate
