        Hello. I was going to purchase this set of bolts but I see this note: "Technical Note: Not compatible with aluminum differential covers." What bolts would be recommended for aluminum differential covers? Thanks~

        • The bolts that we recommend would be 304 stainless steel bolts. You can either get those or zinc coated steel as the aluminum bolts will not react well with the differential covers.

        Have a 88 Mustang gt.Will these work with the ford racing diff cover 8.8 gear that you have on your website?

        • Unfortunately, these bolts will not work with aluminum differential covers and will not work with the Ford Performance differential cover due to that cover being aluminum.

            Great looks and quality

            They look great on the stock steel cover if you clean it up and paint it, but be aware they will not fit on the Ford Racing cast aluminum cover, and probably other aluminum covers.

            Works great

            Bolts worked great. They take a ⅜ 12 point, which would have been nice to been labeled on the package. They look great as well. Highly recommended.

            Differential cover bolts

            They fit well and added looks to the cover. They seem stronger than the factory parts. The manufacturer makes a good quality part.

            Diff bolts

            Beautiful bolts, perfect fit, fast delivery, really accents the aluminum differential cover, there is nothing worse than a great looking differential with rusty bolts, totally happy with everything

            These bolts are high quality material. I’m very happy in knowing that my differential cover is sealed with high quality bolts that I can depend on under both Street and track conditions. 5/5 stars would recommend.

            Great quality

            These bolts were definitely stronger than stock and added a nice accent to the differential. The only bad thing is I changed the cover shortly after and was unable to use these due to them not long enough.

            Show bolts

            The bolts are very nice and look awesome. They will make your diff cover look like a million bucks. Threw me off that they are for chevy although you sell nothing but ford parts,so im not using them.lol. not for that reason,im sure they would work great on a stock cover. I had ordered a ford racing cover which is much much thicker on the edges and the bolts would never be long enough to work. Ordered them thinking i needed them but the cover came with long bolts so thats good. Just spent 25$ on chevy parts ill never use now tho. Bummer.

            too short

            awesome quality bolts and great for the stock diff cover but most aftermarket diff covers (like the gt500 cover i just installed) are thicker so these will only thread in with about two threads. had to go purchase slightly longer bolts. don't waste your time buying these if your installing an aftermarket diff cover.

            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!

            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.

            worked great just as expected

            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.
