Product Details

ARP 201-4605 Head Studs w/12-Point Nuts (U/Cut Studs)

Exact Tolerances for Perfect Alignment

Exact tolerances ensure that gaskets and cylinder heads just glide into position and align perfectly. These ARP Head Studs U/Cut (Under Cut) include 12-point nuts and are manufactured by ARP from premium 8740 chrome moly steel and heat treated to 190,000 psi. They are thread rolled after the heat treating process, which vastly improves their fatigue tolerance compared to studs threaded before heat treatment. High-quality, parallel ground washers included.

Mui bien

All seems great. Had item in stock as on there website and it was shipped quickly.

I got the part I ordered and will be having someone install it soon looks just fine and I love the chat feature as well.. thinking about buying brake shoes now.. a lot of savings

The prices were so much better with Autoplicity I couldn't believe it was the same item. E-mail response came within an hours. Will buy from again.<br><br>Ok, the verdict's still out on this one. Autoplicity said my item was shipped two days ago (two days after ordered), but FEDEX indicates they've only received "shipment information", after four days. I'll follow up when I actually see the order.

Fast shipping, product was excellent .

Autoplicity agent was very helpful over the phone. He answered all my questions & even did some research to make me feel comfortable I was getting the appropriate parts I needed for my car. I was very pleased & will shop Autoplicity again.

I am very glad that my order came in on time and in great condition!

thank you

Very easy and great price.

Superb company! Autoplicity had the lowest price, shipped it quickly, and it was exactly as advertised - couldn't ask for better results!

Easy checkout.

Very easy quick and simple

Fast shipping and email answered fast. I'll shop again. Tahnks
