Product Details

The ARP 123-6021 is a 2-piece connecting rod bolt kit featuring cap screw design and constructed from ARP2000 Pro Series material. These precision-engineered fasteners deliver superior strength and reliability for high-performance engine applications where connecting rod integrity is critical.

Key Features:

  • ARP2000 alloy steel construction capable of 220,000 psi clamp load
  • Cap screw design for secure, precise fastening
  • 2-piece kit for single connecting rod replacement
  • Forged in-house using premium quality materials
  • Heat-treated with 360-degree penetration for uniform strength
  • Threads rolled after heat-treat for up to 10x longer fatigue life
  • CNC-machined to exacting tolerances
  • ARP name stamped on each bolt for quality assurance

About ARP2000 Material:

ARP2000 is a premium alloy steel heat-treated to higher levels than standard 8740 chrome moly, delivering superior clamping force at 220,000 psi tensile strength. This material is widely used in short track and drag racing applications as an upgrade for both steel and aluminum connecting rods. ARP2000 provides excellent resistance to stress corrosion and hydrogen embrittlement when properly installed and maintained.

Why Choose ARP Rod Bolts:

ARP rod bolts are recognized throughout the racing industry as the gold standard for connecting rod fasteners. Independent testing demonstrates ARP bolts deliver ten times the fatigue strength of competing fasteners. Major connecting rod manufacturers specify ARP bolts as original equipment because the bolt has historically been the weak link in connecting rod assemblies. Whether you're building a street performance engine or competition powerplant, ARP rod bolts provide the reliability and strength margin necessary for demanding applications.

Installation Note: Monitor bolt stretch during use and replace when permanent elongation exceeds 0.0005 inches. Always follow proper torque specifications and use recommended lubricants for optimal performance.

The web site is easy to navigate, which made for a good shopping experience. Took a few clicks. Items were on my front porch in 2 days. Very Satisfied with the whole experience. Will use again.

Thank you for having the best price I could find after missing out on Black Friday deals from sites I normally shop. I will definitely keep you in mind for future purchases.

Ordering was about as easy as it can get.

good pricing and easy to order online from Autoplicity

Everything arrived well packaged and in good order... It was shipped promptly, but hey, no accounting for the snow storm in the NW... I think UPS calls it an "act of God"... Thanks

Ordered Monday, delivered Thursday - just as promised. Best price among all reputable on-line parts dealers. Saved at least a third off the most popular dealers.

Great selection and fast shipping. Not to meantion the lowest prices anywhere on the net.

For this being my fist time using your site. I thought it was a smooth site to shop and find my products and than place my order. I also liked the price.
