ARP 640-4500 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

product worked as expected and arrived in a reasonable time.

After shopping around at my local auto parts stores and not liking what they had in stock I decided to go on line and BANG found Autoplicity.com and they had just exactly the black finished lug nuts that I was looking to give my Trailblazer SS a different look with the stock wheels, 5 ⭐️ 's and definitely will recommend them, thanks again Autoplicity.

This was my first time using autoplicity and I was very happy with their service. Great prices and fast shipping.

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.

Very easy webpage to use and search for items by selected vehicle. Shipping was fast and good notification system when order has shipped. Great prices, Would use autoplicity again and would reccomend to everyone.
