Hypermotive is happy to become a direct dealer with ACE manufacturing, after seeing their products and knowing everything is made in the U.S...... from scratch I saw the need to help support our U.S. manufacturers. Ace has been in the heavy duty clutch business since 1967. Starting as a pressure plate grinding company, Ace has grown to become a leader in the heavy duty clutch industry, machining and assembling all of its own clutches and clutch parts. In 1992, Ace introduced its first racing clutch disc for drag racing and street cars, spawning the Ace Racing division. Ace Racing has developed many products since then and has also become a leader in racing clutches for drag racing, circle track and tractor pulling. Ace owns several patents and has expanded itself over the years with a constant flow of new product offerings. While production methods have changed from hand grinders to CNC machining cells, Ace has never compromised quality. Ace Manufacturing is the only clutch manufacturer that produces its own friction materials. The proprietary formulas are used on every line of clutch for tractors, heavy duty trucks, performance street cars, all the way to 9000 HP top fuel dragsters. Along with superior friction materials, Ace’s discs are also made with patented cryogenically processed springs that ensure durability and longevity. Ace offers both organic and cerametallic discs for their POWERFORCE line of clutches. This versatility offers greater performance while extending clutch life and maintaining or improving drivability. Any questions at all just let us know and we'll take care of ya!!
