Product Details

The ARP 154-5606 main cap fastener kit is engineered to eliminate main cap walk and fretting while protecting engine block threads during high-performance and competition applications. This 4-bolt main stud kit provides superior clamping force and reliability compared to factory fasteners.

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 fatigue life
  • Includes hardened parallel-ground washers and high-quality nuts
  • Generous under-head radius design for improved load distribution
  • Select applications include specially designed standoff studs with serrated lock nuts for windage tray mounting

ARP main studs are designed to meet the exacting standards of professional engine builders, providing the ultimate insurance against main cap movement and ensuring consistent torque retention. The superior metallurgy and post-heat-treat thread rolling process creates fasteners that far exceed OEM specifications for competition and high-performance engine builds.

Autoplicity is awesome! Easy check out and quick shipping! Will buy from again!

Great price and super fast shipping!!<br>Will be back!!!

Ordered a Thule hitch and was a little skeptical because I hadn't heard of this company. I was pleasantly surprised by the quickness of response when I ordered, I received an email immediately, and the order arrived just 2 days after it was ordered. This company goes to the top of my list.

Awesome place to get parts from. Went looking all over the city of houston to find a certain light everyone was sold out tried online two "Huge chain name" places were also sold out. Stumbled on Autoplicity and they had just what I needed!

Great store! Best prices, fast fedex shipping. Very satisfied, will buy from Autoplicity again!

Good site easy to search for and find parts. The lowest prices on almost every part I have been able to find for my truck.

Seller was quick and hasle free to deal with. Will purchase again from this seller.
