Product Details

The ARP 155-5201 Main Cap Fastener Kit is engineered to provide superior clamping force and reliability in high-performance and competition engines. This 4-bolt main kit eliminates main cap walk and fretting while protecting the threads in your engine block, ensuring consistent performance under extreme conditions.

Key Features:

  • Manufactured from premium 8740 chrome moly steel for exceptional strength and durability
  • Heat-treated in-house to 200,000 psi tensile strength for maximum clamping force
  • Precision J-form threads rolled after heat-treat provide 1000% stronger threads than conventional fasteners
  • Forged construction with generous under-head radius for superior fatigue resistance
  • Includes hardened parallel-ground washers for optimal load distribution
  • Professional-grade quality meeting the exacting standards of competition engine builders

ARP fasteners feature rolled threads created after heat-treating, a critical manufacturing process that dramatically increases fatigue life compared to fasteners threaded before heat-treat. This kit provides everything needed for a complete main cap installation, delivering the reliability and performance demanded by serious engine builders and racers.

Excellent came quick and was shipped very well.

It was great. Super fast with delivery & product was in great shape.

They had exactly what I was looking for, at a better price than the competitors. The vehicle selector pointed me in the right direction with ease.

We ordered tires and all 4 came the same day. We have not had time time install them yet but they look good.

Website is very easy to use

Very satisfied with this company. Ordered the part from another company and had nothing but problems. We found this place and the part was cheaper and they delivered the right part! Will do busy with again.

Very happy with my purchase. SUPER fast shipping and great communication. Will use again!

Really good prices and fast delivery.

Order #30897. Ordered on Monday, received on Thursday. Exactly what I needed. Can't ask for anything more. Definitely will look at Autoplicity again when I need more parts!

Easy!

Lowest prices and fast shipping made this a great transaction.

I'm very pleased with Autoplicity. i needed a new battery for my antique Ford.After much searching,I found Autoplicity had it for over $25.00 less than the next lowest price I found. My order was shipped in less than 24 hrs. Thank you. I'll be recommending Autoplicity on the Ford forums I belong to

A+ part as advertised, quick shipping.
