OVERSIZE 1KeyParts was founded in 1992 by Tom Foster, as Fit-Rite Body Parts, in New Brunswick, NJ with the idea of bringing better rust repair panels to a market short on quality options. Tom quickly developed a loyal customer base that was happy to be able to offer their customers a product that would reflect well on them and allow body shops to make quality repairs easily.
Fast forward 28 years, a few warehouses later, and “Key Parts, Inc.” has become the gold standard in rust repair. We offer over 4000 individual part numbers to help correctly repair trucks, cars, SUVs from 1947-Current.
