Product Details

The ARP 201-6104 is a complete connecting rod bolt kit featuring ARP2000 alloy steel fasteners, designed to provide superior strength and reliability in high-performance engine applications. ARP rod bolts are the industry standard, trusted by connecting rod manufacturers and racers worldwide for their exceptional fatigue strength and quality construction.

ARP2000 Material: This kit utilizes ARP2000 alloy steel, a premium material capable of achieving clamping loads at 220,000 psi. ARP2000 offers significantly higher strength than standard 8740 chrome moly while maintaining excellent resistance to stress corrosion and hydrogen embrittlement when properly installed. It's an ideal upgrade for short track and drag racing applications in both steel and aluminum connecting rods.

Key Features:

  • Forged in-house at ARP facilities using premium quality materials
  • Heat-treated using specialized vertical racks to ensure complete 360-degree penetration
  • Threads rolled after heat-treatment for up to 10 times longer fatigue strength compared to competitor fasteners
  • Precision CNC-machined to exacting specifications for consistent performance
  • Complete kit with all necessary hardware included

Wave-Loc Technology Benefits:

  • Wave-Loc surface design contacts rod and cap for optimal alignment and reduced fluctuating stress
  • Provides interference fit range of .001 to .005 inches to accommodate factory rod bolt hole tolerances
  • Superior material grain flow compared to knurled bolts that create stress risers
  • Eliminates galling and scoring through smooth contact surfaces
  • Strengthens the connecting rod assembly itself through improved load distribution

Maintenance Note: Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches or more to maintain optimal performance and safety.

Each ARP bolt carries the ARP name stamp as your assurance of quality and authenticity. These fasteners represent the perfect balance of cost-effectiveness and performance for engines operating under high loads and rotational speeds.

You had the part's in which I was looking for The only hang up was trying to match all parts for the sizes that would fit together

So far so good. So far very happy.

I totally recommend the Goodyear "Gatorback belt". I drive an 2001 Tahoe 5.3l, had the squeaky serpentine belt, It was still a good shape belt, but the squeaks were more of a nuisance. So I decided to give the Gatorback Belt a try, and overall I love it. No squeaks, squeals, or any kind of noise. Its very quiet. Autoplicity made it easy for me to check and make sure this belt fit my year and model vehicle. I didn't have to contact customer service for anything, so far (haha).

Quick find, Part number correct, great price and free shipping. What's not to like?

Easy as a slice of pie!

The parts showed up a day early. I was very pleased.

Easy transaction and quality parts

My order #4383 was fulfilled quickly and shipped in a timely fashion. The price was super competative and the web site is user friendly. I will be back for more I'm sure! Shipping should be free for orders over a certain price, say $50?!?!

Great price and received item in a timely and in great condition. Will definitely shop here again!

Autoplicity made finding and ordering my parts simple and easy! Not only did they have the parts in stock and ready to ship, but they were also the cheapest BY FAR saving me nearly 30%!<br><br>The information that they had on the product pages was 100% accurate unlike other car part websites.<br><br>Autoplicity has made a customer for life!
