Product Details

ARP 134-5403 is a high-performance main stud kit designed for 2-bolt main applications, featuring 12-point head fasteners for superior clamping force and reliability in demanding engine builds.

Key Features:

  • Manufactured from 8740 chrome moly steel with heat-treatment to 200,000 psi tensile strength
  • Precision J-form threads rolled after heat-treat for 1000% stronger thread life compared to conventional fasteners
  • 12-point head design for improved wrench engagement and accurate torque application
  • Includes hardened parallel-ground washers and high-quality nuts for complete installation
  • Eliminates main cap walk and fretting while protecting engine block threads
  • Designed for 2-bolt main cap configurations in performance and competition engines

ARP main studs provide critical reliability for high-performance and racing engines where main cap stability is essential. The superior material properties and precision manufacturing ensure consistent clamping force and long-term durability under extreme conditions. Each kit includes all necessary hardware for proper installation.

Parts in stock at a Great price!

The part (hood insulation pad) was competitively priced. Shipping costs were reasonable and delivery time was good. I'm glad I found Autoplicity on the Internet.

Quick and easy

Quick delivery. Tire was as advertised

Awesome transaction and fair prices .

Thank you

The best price!

Product was delivered and item was as discribed. However it did take a little longer to ship than what is the new normal. (3 business days ) shipping address to delivery address is 3 hours by car. Over all experience with this company was good.

I would like more information on delivery scheduled, maybe for it to be morr accurate.

They had an item that was somewhat hard to find at a reasonable price. Glad I found them.

Nice and easy

More than I wanted to spend on a cargo carrier, and I'm worried it won't fit my vehicle. Hoping for the best!

The best prices and fast shipping!

Absolutely the best bargain you'll find! Don't pay retail mark up at the parts store, buy at Autoplicity and know you're saving money.<br>.

great service, even better price! Would recommend Autoplicity to anyone.

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.
