Let’s say you’ve got a Ford of the 1965-1971 vintage, with a 390, 427, 428, or 429 under the hood. First of all, we’re jealous and we hate you. Envy aside, though, you might be looking for a replacement for the stock Long-style clutch – something with a little more holding power, but you don’t want to have to jump through hoops to do the swap. Centerforce has what you’re looking for with two new 11-inch diameter clutch assemblies that are direct bolt-in replacements offering better torque capacity and a diaphragm spring assembly for improved reliability.

Official Press Release:

Centerforce® is proud to introduce this 11” Centerforce II clutch assembly that has an increased holding capacity over the standard 11” long style clutch assembly for 1965 through 1971 vehicles equipped with 390”, 427”, 428”, and 429” engines. This new clutch assembly replaces the stock plate with this 11-inch, more reliable diaphragm clutch assembly that is designed as a direct bolt in for perfect fit and function. Centerforce strives to provide the best products on the market at any performance level by constantly testing different materials and designs to find the best combination.
