Product Details

The ARP 156-5202 Main Cap Fasteners are engineered to eliminate main cap walk and fretting while protecting the threads in your engine block. This 4-bolt main stud kit delivers the precision and reliability demanded by professional engine builders and high-performance applications.

Key Features:

  • Manufactured from 8740 chrome moly steel for exceptional strength and durability
  • Heat-treated in-house to 200,000 psi tensile strength
  • Precision J-form threads rolled after heat-treat for 1000% stronger threads than conventional fasteners
  • Forged construction with generous under-head radius for maximum reliability
  • Complete kit includes hardened parallel-ground washers and high-quality nuts
  • Rolling threads after heat-treating provides approximately 1000% longer fatigue life

ARP main fasteners represent a significant upgrade over OEM hardware, providing the clamping force consistency and durability required for high-performance and competition engines. The precision manufacturing process ensures each fastener meets exacting tolerances for proper main cap retention and engine longevity.

I hope it matters to you that I paid extra to buy from you and not Amazon :)

Very good

Best possible customer service! Thanks so much! HIGHLY recommended!!

Best price, easy order process.

I have a corporate credit card with separate billing/shipping address requirements. After my initial purchase I was then solicited to fill out an additional Credit Card form. very inconvenient.

Delivery took a little longer than expected but product is in new condition as said. I would use this company again.

<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!

Best prices on the net that I found anyway.

excellent service, i had to wait a few days for the order to be processesed, but only because i ordered on Friday afternoon, but love the site!

This was my first purchase from Autoplicity, and it was an excellent experience. They had the Motive brake bleeder adapter I needed at the best price I could find on the web. Shipping was prompt and the transaction was super smooth. Thanks!

Shipped out fast. Prices are very competitive. Couldn't ask for more.
