Who is SPEC Clutch?

Back in the day, engines were only rated at less than 50hp. Having a 100hp vehicle back then is considered as a performance race engine in today's standard. But as technology evolves so is the horspower.

Today, you see engines having more than 1000hp, some even reaching five times that number. And with that much output, there is a need for a drivetrain component that would be able to handle this much power. SPEC Clutch is a company that can deliver just that.

Based in Bessemer, Alabama, SPEC Clutch was founded by automotive enthusiasts and racers who were motivated to build a better product than what was available to them. SPEC Clutch assembled a team of experienced engineers, clutch builders, machinists, and other petrolheads to build the brand, which began producing clutches all day in a 5,000 square foot building. Using their expertise, they were able to create a clutch system that is not only easy to use on the street but also can perform on the track. 

Their clutches are considered some of the best ones available in the market and has exceeded the expectation of many enthusiasts everywhere. Due to the increasing demand for their products, the company has expanded its operation and now resides in a purpose-built 30,000 square-foot state-of-the-art facility, where they design, test, and manufacture all of their products in-house. It allows them to maintain their high level standard and enables them to control the manufacturing of their parts. This means that all clutches, flywheels, and pressure plates are designed under the same roof and optimized to work together to deliver the best results possible.

Sheer Dedication to the Industry

SPEC Clutch has since become an industry-leading company renowned for its high-performance clutches and flywheels available for nearly every vehicle and application out there.

This company provides the only flywheels on the market manufactured to a .001 machine tolerance to provide ideal rotational integrity in even the toughest of conditions. 

SPEC Clutch has become a mainstay in a variety of motorsports and employs a certain number of racers at hand to ensure its products work. SPEC Clutch also takes the time to engage in a number of different racing programs in order to continue researching and developing its components and systems in real-life competitions. After all, the ultimate test is seeing if the product does its job out there in the real world.
