    Great looks and great security

    One can never go wrong with ARP fasteners. These bolts look awesome on my aluminum diff cover, and I love the peace of mind I feel knowing that my assembly is that much more secure and strengthened by these fasteners. A very worthwhile investment. I thoroughly recommend them.

    ARP Stainless Steel Differential Cover Bolts - 8.8in (86-14 GT, Mach 1; 07-12 GT500; 93-04 Cobra; 11-14 V6)

    Purchased the ARP differential bolt kit for my Mustang. They bolts are the correct length for the stock differential cover, however did not work with the Steeda finned differential cover that i had also purchased. The thickness of the cover was larger then factory cover, so the bolts were not long enough. Keep that in mind when purchasing.

    ARP is a must have!

    Can't ever go wrong with ARP. Strength, good looks, and quality! With my ford racing differential cover and these bolts, i feel secure with my rear end and 3:73s. The 12 point design I like too! ARP always goes the extra mile. I recommend these to everyone. Thanks am! Satisfied as always!

    After breaking a stock bolt I decided to go with arp and good thing I did, the stockers seemed weak compared to my new and improved arp bolts. I recommend these to everyone even if you're simply just going to go through your rear differential to check things out.
