Thread: Bolt head in rear diff..

I replaced mine with ARP bolts, with a smooth face, after needing to replace my crown wheel and pinion after it chewed though a few bolt heads. In my opinion using serrated head bolts against cast iron was a very poor design.

I sourced my ARP bolts from a local engine reconditioner. This is a list of suppliers in Australia, The Official ARP Web Site | Dealer Locator
