ARP 644-3500 Differentials & Ring & Pinions

Standard 12Point Bolt
5Pieces

Now you can use premium quality ARP stainless steel or chrome moly fasteners to install most anything on a car, boat or trailer. The specially alloyed ARP 300 stainless steel and heat-treated 8740 chrome moly bolts (black oxide finish) are nominally rated at 180,000 psi tensile strength to provide a substantial extra margin of safety over Grade 8 hardware.

Whats more, you cant beat the gorgeous looks of ARPs specially polished stainless steel fasteners, and their ability to resist rust. Theyre truly maintenance free!

You can get 5-packs (washers included) of any diameter bolt from 1/4 to 1/2 or M6 to M12 in lengths ranging from 1/2 to 6, with ARP12-point heads. Matching nuts are also available

Great price and perfect match on parts!

Awesome deal and fast shipping. Will be back!

Best price on the internet for my parts. Shipped out the next morning.

Ordered a Dee Zee bed mat for my truck. Got it right away and it fits like a glove!!!

Very easy to navigate web site. Received my order in excellent condition in a timely manner. Recommend Autoplicity as a company with which to conduct business.

Autoplicity had the best price on the item I wanted. Order process was a little odd. I didn't get any confirmation of my order being placed. So 2 days later I sent an email asking if they had received it. They answered me very quickly, sent me an order confirmation with tracking number, and it turns out my item had already shipped so I had it the next day. So ordered 5/1 and had it in my hand 5/4.

I got the items exactly as described with VERY fast shipping. i highly recommend them to everyone. And I will definitely be shopping there again!

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

Same day shipping. 20 Dollars cheaper than everywhere else!

Item was shipped fast and exactly what I ordered. Great price as well.

Super quick service! Great price and I received the product the day after I ordered it.
