Stage 2 Kit (485 ft/lbs)

Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity. The hub comes in either Sprung or Rigid and is application dependant. The double sprung hud features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Best for street, drag, pulling and autocross.

Stage 2+ Kit (545 ft/lbs)

Features a multi-friction disc in a full faced configuration with carbon semi-metallic on one side and Kevlar on the other. Bridging the gap between stage 2 and stage 3, the 2+ offers drivability and engagement quality characteristic of the stage 2, but with a 15-20% higher torque capacity. The hub comes in either Sprung or Rigid and is application dependant. The double sprung hud features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Great for street, drag, autocross, road racing, pulling, rallye and drift.

Stage 3 Kit (580 ft/lbs)

Features a carbon semi-metallic 4 or 6 (application dependant) puck sprung or ridgid hub disc that has been the leading puck clutch in drivability, life and torque capacity. This unit is designed for street and race cars that require an aggressive but streetable engagement and high torque capacity. The hub comes in either Sprung or Rigid and is application dependant. The double sprung hud features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Also available in 3 puck configuration. Great for street, drag, road racing, pulling, rallye and drift.

Stage 3+ Kit (671 ft/lbs)

The flagship stage for a high powered street or race car that requires a manageable and friendly engagement, the stage 3+ features a carbon semi-metallic full faced material that offers unparalleled life, friction co-efficient and drivability characteristics in one single package. The hub comes in either Sprung or Rigid and is application dependant. The double sprung hud features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. Great for street, drag, drift, autocross, road racing, pulling, rallye and drift.

Stage 4 Kit (580 ft/lbs)

This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. Best for drag racing, road racing, pulling, rallye and drift.

Stage 5 Kit (820 ft/lbs)

Stage 5 kits feature a full-metallic disc with the highest possible friction co-efficient. Street drivable but not street-friendly. The hub is solid 12-rivet and the assembly is heat treated for strength and durability. Best for extreme street and drag racing.
