Made in the USA. Spec clutch is a leader in manufacturing street high performance aftermarket clutches, flywheels and pressure plates. Spec clutches are known for maintaining the stock clutch pedal feel while providing higher clamping force than OEM clutch. Each clutch is manufactured to the exact OEM specification so there are no fitment problems. If probably used a Spec Clutch will last you as long as your car, truck or SUV.

If you are looking for replacement for your stock clutch we recommend stage(1)-stage(3), for highly modified street cars we recommend stage(4)-stage(5) and for drivers who love the rush of going fast we recommend twin clutch kit.

What is the difference between stages?

Stage One: High clamp pressure plate, steel-backed woven organic disk, bearings and tool.
For bolt on naturally aspirated and mildly modified forced induction engines. Stock-like daily drivability and very good wear characteristics.

Stage Two: High clamp pressure plate, segmented chatter-free Kevlar disc, bearings and tool.
For all mild to moderately modified naturally aspirated and power adder engines. (Also good for stock power levels and spirited driving when good daily drivability and extremely long life are the goal.) Stock-like daily drivability and EXCELLENT wear characteristics.

Stage Three: High-clamp pressure plate, 3-piece disc with carbon or ceramic material, bearings and a tool. ULTIMATE STREET/STRIP CLUTCH! Sharp but smooth engagement with light pedal.
For heavily modified street and race engines. Offers sufficient daily drivability with a comfortable pedal feel and quick engagement. Offers good wear characteristics under low and high stress usage.

Stage Four: High-clamp pressure plate, 2-piece rigid disc, bearings and a tool. Available in 3 or 6 wing design for serious road racing and drag racing.
For heavily modified engines or engines of any modification level being used in the above driving environments, where an instantaneous engagement and light weight are beneficial. Not street-friendly due to harsh engagement.

Stage Five: High-clamp load pressure plate, iron disc, bearings and a tool.
For extremely modified drag race and pulling engines, or applications that call for a ‘slipper’ clutch/progressive torque-induced engagement. These clutches are best ordered as custom configured and should be ordered after providing specific information about the car and it’s purpose to a SPEC technical assistant. Not street-friendly due to harsh engagement.
