S.P.E.C. Inc, the innovator in LSX clutch technology, introduces their new line of single disc performance clutches and flywheels for LSX powered applications. The Super Single line is now the standard offering and features torque capacity increases of 150 ft lbs per stage over the previous generation SPEC units, with a pedal effort reduction of over 25%!
The clutch kits are available in 7 different single disc stages, supporting all power levels and drivability requirements up to an amazing 967 pound feet torque for the street/strip units and 1100 ft lbs for drag specific units.
The SPEC Super Single not only delivers on performance and drivability, but value, as well. SPEC is maintaining MSRP from the previous generation kits!
SPEC Stage 2 clutch kit for 2004-07 CTS-V. High clamp pressure plate, segmented chatter-free Kevlar disc, TO bearing, pilot bearing and tool. 690 ft lbs tq capacity - 3800 psi pressure plate.
Stage 2 clutches are recommended for mildly upgraded vehicles and/or with a power adder, yet still offering an excellent choice for a daily driver and great holding capabilities for strip use. A segmented Kevlar disk is used on the Stage 2 clutch kits.
For all modified engines making more torque than the Stage 2 can support, the 2+ maintains stage 2 feel for good daily drivability and offers very good wear characteristics, but provides a higher torque capacity (620 ft/Ibs). The disk is a composite multi-friction carbon-kevlar material. Make your selection below.
Includes: Pressure plate, clutch disc, TO bearing, pilot bearing, and alignment tool.
For years lightweight flywheels have been used to transfer energy from an engine to the ground more efficiently, resulting in horsepower and torque gains, quicker revving and less internal engine wear. The SPEC aluminum pressure plates offer the same benefits, and the reduction in mass is more effective since the pressure plate extends further from the crank flange.
NOTE: C6 and CTS-V clutch kits are flywheel specific. Be sure to check part number so it corresponds to the specific flywheel your using. New flywheels can be purchased under the flywheel section.
