HPR clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft. In these devices, one shaft is typically attached to an engine or other power unit (the driving member) while the other shaft (the driven member) provides output power for work.

Performance car parts, such as a performance clutch, will improve gear changes and ride quality.

Available in Many Different Friction Materials & Stages:

FRICTION MATERIALS:

Organic woven metal-fiber delivers smooth engagement and is the choice of original-equipment when it comes to clutch disc friction material. It requires minimal-to-no break in period. This material can overheat with repeated abuse.

Kevlar is a highly durable material that has similar engagement characteristics as organic. When segmented, Kevlar provides better heat dissipation. This material requires a 500 to 800 miles (800-1280Km) break in period.

Ceramic is a very high temperature resistant material. It's generally utilized in puck style disc for high horsepower and race applications. This material will wear flywheel surfaces faster than organic and Kevlar, especially in stop and go traffic situations.

Ferramic is an extremely high temperature resistant material. It has the best friction coefficient at high temperature. The engagement is more aggressive than ceramic and is harsher on the flywheel surface. When contaminated with oil or grease, this material can fuse to the flywheel or pressure plate's riding surface. This material is only available on custom orders.


STAGES (DAILY / SPORT / RACING):

Stage 1 (Daily Driving)

A smooth engagement is achieved when combining an OE quality organic disc with a mild clamp load increased pressure plate. This stage increases the torque capacity by 15-20% making it a perfect choice for the daily driven vehicle with the typical bolt-on. 

Stage 2 (Sport Performance Stage I Driving)

A dual friction disk that incorporates a steel back plated segmented Kevlar facing on the pressure plate side while keeping the organic on the flywheel side, further increasing the torque capacity.  Very popular with showroom, stock racing or touring cars where the engine output is within 40% of the OE offering

Stage 3 (Sport Performance Stage II Driving)

When it comes to friction coefficient, Kevlar is a major improvement over an organic composite yet has similar engagement characteristics.  A full steel back plated segmented Kevlar disc combined with our modified pressure plate improves the torque capacity by 40-60%.  The stage 3 is ideal for the occasional track days and milder forced induction setups. 

Stage 4 (Racing Street Legal)

The stage 4 is our best seller and lets you choose between a 4 or 6 puck sprung disc for more aggressive shifting.  The pressure plate and puck style disc combination yields an increase in torque capacity of 80-100%. In addition, it provides a more direct feedback. 

Although recommended for racing as well as forced induction applications, the ceramic buttons do have a wide operational range which allows for daily driving. 

Stage 5 (Racing Off Street)

An un-sprung 3 or 4 puck disc with ceramic buttons contribute in making the stage 5 a full race and drag clutch.
