Product Details

The ARP 203-5406 main cap stud kit is engineered to eliminate main cap walk and fretting while protecting the threads in your engine block. This comprehensive kit is designed for 2-bolt main applications and delivers superior clamping force and reliability for high-performance and competition engines.

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 reliability
  • Precision J-form threads rolled after heat-treat, providing threads that are 1000% stronger than conventional fasteners
  • Includes hardened parallel-ground washers and high-quality nuts for complete installation
  • Rolled threads after heat-treating provide approximately 1000% longer fatigue life than pre-threaded fasteners
  • Generous under-head radius design reduces stress concentrations

ARP main studs are the preferred choice of professional engine builders who demand exacting standards and proven performance. By using studs instead of bolts, you ensure more accurate and consistent torque values, reduced main cap movement, and improved engine longevity. This kit comes complete with all necessary hardware for a professional installation.

I've had issues with Autoplicity in the past, but this transaction was very smooth.

Product install was a pain and parts didn't fit together properly, but the experience from autoplicity was great

I purchased from Amazon the same tires. But I had to order a bigger size because Ive been hittin a lot of pot holes so these are going to protect my rim better than the 225/30/20s

I thought my order was going to take longer to ship and it surprised me after I called Autoplicity I thought another few days before it shipped and it arrived. The lowest price I found on my Mishimoto radiator was on Autoplicity.

Fast shipping, very nice communication by phone, item as described, Thanks

Not only were the Items I orded wereed a very reasonable price, they were shipped promptly, arrived in perfect shape, and are already being used. I am extremely satisfied with Autoplicity!

Great pricing and fast delivery

Very pleased with the exceptional service. The replacement rear window gas struts for my '02 Jeep TJ Sahara are extremely high quality and identical to the original ones replaced. Outstanding distributor!

I did enjoy shopping and ordering the items from this place , ordering it was quick and easy,thank you.

Good fast shipping. Easy ordering.

Fast and easy!

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!

Autoplicity had the best price on the Thule bike rack we purchased. Delivery took a little longer than expected but they kept me appraised of the shipping status which we appreciated. I would definitely order from them again.
