SPEC LS1 Aluminum Pressure Plate


Model Number: ALUMPP

This is NOT sold individually, this is an optional upgrade to be added with a clutch purchase.

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.
