Product Details

Designed specifically for small block Chevrolet engines with 2-bolt mains and small journal crankshafts, ARP's High Performance Series main bolts deliver professional-grade reliability for competition and performance builds. These main bolts secure the main bearing caps to the engine block, ensuring proper crankshaft support under high stress conditions.

Key Features:

  • Forged from premium 8740 chrome moly steel for exceptional strength and durability
  • Rated at 180,000 psi tensile strength—far superior to OEM fasteners and Grade 8 hardware
  • Threads rolled after heat-treating provide approximately 2,000% better fatigue strength than bolts threaded before heat-treatment
  • Reduced wrenching head design with large underhead radius minimizes stress concentrations
  • Rolled threads ensure maximum reliability and extended service life
  • Hardened parallel-ground washers included for even load distribution

ARP's High Performance Series main bolts are engineered to meet the exacting standards of professional engine builders and provide a significant upgrade over factory fasteners. Perfect for street performance, racing, and high-output engine builds where main cap security is critical.

so far good.

Great product, came as advertised.

This is my first experience ordering from Autoplicity. I was searching for tires online and found that tire rack and Big O tires both listed the size/brand that I needed as out of stock. Auto closely said that they had many in stock and at the best prices. I was pleasantly surprised to receive them within 2 to 3 days. I will definitely be ordering from them again in the near future.

Order was on time and Great quality.

Fast delivery time excellent service

Great product, fast delivery.

Prices are among the lowest around. Had a change with my order. Customer support team was quick to respond to emails and make corrections. Will order from Autoplicity again.

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.

I bought this item for my fiance and he loves it! He was completely happy with the price we paid...

Found what I needed- no probelm.

very easy to find merchandise, transaction was simple, received confirmation quickly, good experience so far

Autoplicity has made my parts search so much easier. With the best price gurantee, i can now make autoplicity my one-stop shop for all my parts needs.

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.
