SPEC Clutch Stage 2+ - Ford Mustang 2011 Mustang GT V8 5.0 and 2011-2014 V6 3.7L - SF503H-2 / SF503H-2T
SPEC is a Manufacturer of street high performance and racing clutches and flywheels. Featuring Clutch Kits From street kit Stage 1, 2, 2+, 3, and 3+ to Race Kits Stage 4 and 5. And now the SPEC Super Twin with TQ ratings of over 1500 FT TQ! Every SPEC Clutch Kit and Flywheel has been SFI Approved.
This Stage 2+ Clutch Kit 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 dependent. The double sprung hud features spring cover relieves for flexibility and both hubs use heat treated components for strength and durability. The SPEC Stage 2+ Clutches are designed for all mild to moderately modified naturally aspirated and power added engines, but can be used with stock power levels without sacrificing driveability or excessive wear characteristics. They are the perfect balance of driveability and durability that makes them a great choice for Mustangs that see a lot of time on the street as well as the strip and track. Great for street, drag, autocross, road racing, pulling, rally and drift.
