Product Details

The ARP 209-5402 Main Stud Kit is engineered for 2-bolt main applications, delivering superior clamping force and reliability for high-performance and competition engines. This comprehensive kit eliminates main cap walk and fretting while protecting the threads in your engine block, ensuring long-term durability 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
  • Includes hardened parallel-ground washers and high-quality nuts for proper load distribution
  • Complete kit with all necessary hardware for installation
  • Designed to meet the exacting standards of professional engine builders

ARP's post-heat-treat thread rolling process creates fasteners with significantly longer fatigue life compared to fasteners threaded before heat-treating. The generous under-head radius and rolled threads deliver the utmost reliability for demanding racing and performance applications where engine durability is critical.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

Great pricing and quick shipping. I'll be using them again for sure.

This is my first time ordering from autoplicity. Everything was prompt. Easy payment options, fast shipping. Greats parts and cheapest price.
