## Description

To maintain a reputation for "zero defects", ensure optimum quality control, and produce fasteners of exceptionally high quality, ARP controls all aspects of the manufacturing process, performing all operations in-house where they can be closely monitored. ARP takes extraordinary steps to produce the very finest products of their kind on the market today. These stainless steel rear end cover bolts are an excellent example of ARP's craftsmanship, and an easy way to enhance the appearance of any GM 12-bolt rear end setup. The stainless steel won't rust, and it offers a lustrous contrast to a painted OEM cover, or perfectly compliment a chrome plated aftermarket version. Rated at 170,000 psi, these sturdy bolts are much stronger than stock (or even Grade 8) hardware, and the threads are precision machined for secure engagement. The kit even comes complete with washers.

Review: Great quality - Perfect for replacing hardware on Ford 8.8 differential. You will need to keep two of the longer factory bolts that hold the harness for certain years. Mine was 2021 F150
Review: Great touch to the upgraded diff cover - Perfect touch to give what SHOULD have been the correct OEM addition, for better quality. Great quality and look to add to what is a high value vehicle. Ford got it wrong so WE have to get it right! Don't slip after the obvious upgrade. Finish the job with these!

Very nice bolts, some say too long for a 12 bolt rear end but they're the same length as the factory.
