PROFORM® line was the first to popularize affordable and 100% NEW (as opposed to "rebuilt") starters, alternators, stock harmonic balancers, and distributors; the first to offer the 2-Pc timing chain cover, the 2-stage in-line fuel filter, HEI distributor tune-up kits, and direct-replacement carburetor main bodies; the holder of the patent rights to corrosion resistant battery hold-down J-hooks, Slotlok™ wire dividers, the no-mess oil drain plug, the one-piece drop-on valve cover hold-down, and the harmonic balancer cover. Affordability. Quality. Performance. PROFORM.
