Product Details

The ARP 156-5901 is a premium main stud kit designed for 4-bolt main applications with windage tray provisions. Engineered to eliminate main cap walk and fretting while protecting engine block threads, this complete kit delivers the reliability demanded by professional engine builders.

Key Features:

  • Forged from 8740 chrome moly steel for maximum 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
  • 12-point head design for precise torque application
  • Specially designed standoff studs with serrated lock nuts for windage tray mounting
  • Hardened parallel-ground washers and high-quality nuts included

ARP's post-heat-treat thread rolling process creates a fastener with exceptional fatigue life and reliability. The windage tray studs feature serrated lock nuts that securely position and lock the windage tray in place, ensuring proper oil control in high-performance and competition engines. This kit provides the ultimate insurance against main bearing failure in demanding applications.

Excellent

Navigating the website was pretty simple and the delivery time was outstanding. However, the product picture and discription online was not the product I received.

Very fast

They had a better price than anyone else on the internet for the part I needed. And the shipping was fairly quick.

Great prices and great service with fast shipping!

Great price!

I would recommend your company to anyone.

<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!

Excellant

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!

Great Communication and instant shipping. Well done!

Great prices and fast shipping. What more are you looking for?

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!
