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 98-02 LS1 F-Body. 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.

From SPEC is their new aluminum pressure plate. This option replaces the old "Lightweight Pressure Plate" option where they drilled holes in the outside of the pressure plate to reduce rotating mass. The benefit of the aluminum pressure plate is comparable to gains from a lightweight flywheel, and in most cases is less costly.

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.

These plates can be used with an OE flywheel or in conjunction with a lightweight flywheel for a more drastic improvement. Drivability is virtually unchanged, and the aluminum plates offer the same high clamp loads, and in some cases more clamp load, than the standard steel SPEC high performance pressure plates. SPEC uses only aerospace quality aluminum and fasteners and most SPEC aluminum pressure plates carry SFI certification. Make your selection below:
