Collection: Diamond Racing Products
Diamond Racing Products' original founders, Jim “Diamond” Cavallaro, Nick Plantas, & Butch Eldkins, were a group of racers & entrepreneurs who combined resources to form the company’s first iteration. It didn’t take long for them to carve a niche in the high-performance game, with Diamond quickly becoming involved with Super Stock & Pro Stock in the early ‘70s. Like many companies of that ilk & era, Diamond wasn’t focused on doing just one thing. Instead, they did it all. Cylinder head porting, engine building, & all other manners of performance took place under Diamond’s roof. As demand for performance peaked, Diamond started to machine their own pistons using forging blanks finished in-house to their rigid specs & quality. That business plan continued into the early ‘90s when a new owner, Bob Fox, decided to shift the company’s considerable engineering resources solely to piston development.
