STILLEN High Performance Clutch & Aluminum Flywheel Kit

STILLEN offers combination kits for the most popular high performance clutch upgrades, and combines them with a lightened billet aluminum flywheel for maximum performance.

STILLEN High Performance Clutch and Aluminum Flywheel Combo includes ACT Heavy Duty Pressure Plate and ACT Performance Organic Street Disc and STILLEN Lightweight Aluminum Flywheel.

ACT Heavy Duty Pressure Plates provide increased torque capacity, durability, and extended clutch life. What makes ACT Pressure Plates the highest standard in the industry? First, ACT manufacturing always begins with new units. ACT Pressure Plates are not rebuilt from worn out parts. Second, pressure is increased the right way. Altering the geometry alone is not enough.

Instead, ACT engineers a stronger diaphragm. ACT diaphragms are heat-treated using an exclusive 3-stage process and the release bearing contact area is hardened to reduce wear. Third, ACT designs the pressure and release travel of the unit to be in the optimum working range. Finally, ACT assures consistency and precision by using proven assembly procedures.

Every unit ACT produces is accurately balanced and tested. Most ACT pressure plates are also available in ductile iron, offering strength and safety for high RPM racing. ACT Street Discs are designed for smooth engagement, quiet operation and improved durability using only the best organic, spring center designs.

When a special ACT Performance Organic Street Disc is available, the suffix "SS" will appear. These discs use special steel backed performance linings designed to withstand high heat and abuse. Most of these "SS" discs are also modified for quicker shifting.

What is all the hype about different lining materials available? ACT still contends that nothing can beat a good quality organic disc for street use. Virtually all the premium sport car manufacturers use organic discs. Actual product may vary slightly from image.

In Addition, these billet aluminum flywheels are typically just over half the weight of the stock iron unit. With the reduced weight, less power is needed to overcome flywheel inertia. The result is a quicker revving, more responsive motor.

Both clutches and flywheels are also sold separately.



About STILLEN Parts & Accessories

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.
