Shopper Award

An excellent performance upgrade. Lightened steel flywheels are susceptible to shattering under aggressive driving conditions. Because aluminum is lighter than steel, we are able to produce aluminum flywheels utilizing stock dimensions. Aluminum flywheels are perfect for road racers looking for quicker revs. It is also a nice complement for turbocharged cars experiencing lag.

Flywheel Features:
-Reduced mass equals increased acceleration.
-A lightweight flywheel works particularly well with turbo-charged engines because it reduces typical turbo lag.
-Increased supercharger efficiency due to less parasitic drag on the crank.
-Improved mid-range torque in a normally aspirated engine due to not having to overcome the heavy weight of a stock flywheel.
-CM uses only 6061-T6 aircraft grade or better billet aluminum in the manufacturer of its flywheels.
-CM uses High Carbon steel for the friction surface. (Replaceable)
-CM uses an OEM steel ring gear secured by bolts.
-CM offers a 90-day warranty.
-CM Billet Aluminum Flywheels meet SFI Spec 1.1 or 1.2

About Clutch Masters

Since its inception in 2002, Clutch Masters has set the standard for quality, performance, and durability with its lineup of heavy-duty and track-ready clutches. Its high-performance clutch systems are widely known for being technologically superior to anything else on the market. With more than 40 years of industry experience, Clutch Masters has been able to research hundreds of friction materials and develop a line of clutches that delivers unmatched performance in even the harshest conditions. The company’s thorough processes and dedication to quality earned it a solid reputation and respect among car enthusiasts around the globe.

High-Quality Clutches

Many of the traditional high-performance aftermarket clutch kits can cause excessively increased pedal pressure. Such action places an unsafe amount of pressure on the delicate crankshaft thrust bearing found in a number of today’s sport compact vehicles. Clutch Masters’ design team knows that placing undue stress on the thrust bearing causes it to prematurely wear or completely fail, leading to missed shifts, damaged clutch parts, and internal engine damage. This is where the unique Clutch Masters clutch system comes in.

Clutch Masters uses Hi-Leverage technology in its pressure plates, which significantly increases clamping force without an unnecessary rise in pedal pressure. Discs are designed either with reduced Marcel or a solid hub design to take advantage of the company’s Hi-Leverage pressure plate. The combination of these advanced technologies creates the finest clutch system available on the market today.

Why Choose Clutch Masters?

Each Clutch Masters’ clutch is specifically designed and engineered for varying stages of high-performance and/or racing applications. There is a system for everyone from the street performance enthusiast who requires more grab while preserving everyday drivability, to the racer who needs a clutch to survive the grueling conditions of competition driving. 

Clutch Masters’ flywheel kits deliver more transmittable torque and stability, offer a longer service life, and boast superior thermal resistance than those of the competition. For this reason, Clutch Masters’ products are highly regarded among high-performance tuned vehicles that compete in motorsports. They have also proven to be very advantageous for towing cargo trailers with heavy loads.
