Product Details

The ARP 255-5702 main stud kit is engineered for Ford 4-bolt main applications with factory windage trays, providing superior clamping force and main cap stability for high-performance and competition engines. This complete fastener system eliminates main cap walk and fretting while protecting engine block threads from damage.

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 provide 1000% stronger fatigue life compared to conventional fasteners
  • Specially designed standoff studs with serrated lock nuts for secure windage tray mounting
  • Includes hardened parallel-ground washers and high-quality nuts for proper load distribution
  • Compatible with Ford Motor Sport windage trays on 4-bolt main applications

ARP main studs offer significant advantages over OEM bolts by maintaining consistent clamping force under extreme loads and temperature cycling. The superior thread engagement and material properties make this kit ideal for stroker builds, forced induction applications, and high-RPM racing engines where main cap stability is critical.

Great prices. Fast shipping I will order more stuff in the future from here thanks

Great prices, have bought from before and will buy from again.

Super fast shipping, Best pricing that I was able to find on the internet. Will do business with them again and recommend them to my friends.

Great prices

Trustworthy seller. This is my second order. Got it quickly. good job!

Autoplicity had the best price on the item I wanted. Order process was a little odd. I didn't get any confirmation of my order being placed. So 2 days later I sent an email asking if they had received it. They answered me very quickly, sent me an order confirmation with tracking number, and it turns out my item had already shipped so I had it the next day. So ordered 5/1 and had it in my hand 5/4.

Great Product, you canot find a better price!!!<br><br>K&N Air Intake for 2010 Camaro 6.2

Searched local and web stores for an Exedy clutch kit. Even with shipping, Autoplicity beat the others on price. They are an Amazon seller so I was not as concerned about buying from them as I usually am when buying things on the web.

Fast shipping even around the holidays and the cheapest price I could find on my Thule t2 bike rack I would buy here again
