Spec Clutch SS103H Stage 2 Plus High-Performance Clutch Kit

The SPEC SS103H Stage 2 PLUS Clutch Kit is engineered to bridge the gap between the Stage 2 and Stage 3 clutch systems, delivering a meaningful step up in torque capacity while preserving the street-friendly engagement feel SPEC's Stage 2 is known for. Ideal for modified engines that have outgrown a standard Stage 2 clutch, this kit offers a 15–20% higher torque capacity without sacrificing daily drivability.

At the heart of this kit is a multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This composite pairing delivers excellent wear characteristics, progressive engagement, and the durability needed for demanding performance applications. The hub features a double-sprung design with spring cover relieves for added flexibility, along with heat-treated components for superior strength and longevity.

SPEC clutches are designed, hand-built, and tested in the USA, and every SPEC clutch kit is SFI approved. The Stage 2 PLUS is rated for street/strip use, making it a versatile upgrade for performance-built vehicles that demand more than a standard Stage 2 can deliver.
