Product Details

The ARP 204-6003 is a complete connecting rod bolt kit featuring ARP2000 alloy steel fasteners with the patented Wave-Loc design. Engineered to eliminate the weakest link in connecting rod assemblies, these precision-manufactured bolts deliver superior strength and reliability for high-performance racing applications.

ARP2000 Material Advantages:

ARP2000 alloy steel is heat-treated to achieve tensile strengths of 220,000 psi, providing significantly higher clamping loads than standard 8740 chrome moly bolts. This material offers excellent fatigue resistance while remaining cost-effective for short track and drag racing applications. Testing demonstrates that ARP rod bolts deliver ten times the fatigue strength of competing fasteners.

Wave-Loc Technology:

  • Patented Wave-Loc surface design creates optimal alignment between rod and cap while reducing fluctuating stress
  • Provides interference fit of .001 to .005 inches to accommodate OEM connecting rod bolt hole tolerances
  • Superior grain flow compared to knurled bolts that create stress risers
  • Smooth contact surface virtually eliminates galling and scoring of the rod
  • Strengthens the connecting rod itself through improved load distribution

Manufacturing Excellence:

  • Forged in-house using premium quality materials
  • Heat-treated on vertical racks for complete 360-degree penetration
  • Threads rolled after heat-treat to maximize fatigue life
  • Precision CNC-machined to exacting tolerances
  • Each bolt proudly stamped with the ARP name for quality assurance

Important: Monitor bolt stretch and replace any fastener that has permanently elongated by .0005 inches to ensure continued reliability.

My overall experience was great. I wish I could've got the part a little sooner

Great deals and mobile website. Need more info about products, though. Wasn't sure if these tires are new or, used.

Ordering was smooth and I had no issues at all!

Good

Shipping was very fast. But no tracking number was given and pretty much was a guessing game. You all should work on that!

Fast .friendly . Thank you

Good selections! Easy orderiing!

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

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!

User friendly system

They beat everyones price on-line and in town and it only took ten days to get my tire delivered to my front door I will shop with Autoplicity again I have told all my friends about the low price already Thank You

Ordered a couple K&N oil filters for my bike and they were the cheapest by far. The order arrived quickly and exactly as promised. They kept me informed of the status all the way. i would definitely buy from them again! Ed

Good prices, love the Amazon payments bc I use Amazon all the time

The order number 15547 tailgate lock fit perfectly. The shipping was very fast, ordered on Tuesday, delivered on Saturday. Will order from again.

The web site could use some updating or either there is a Glitch somewhere. I had to call to check on my order but it was already being shipped. They were on he ball, I just believe they are having computer troubles. Autoplicity had the best price I could find On my Bully Dog. Thanks Again!!

Ordered a VP Racing fuel container and fill tube late Friday and it's already on the way. <br>Best price online and very quick service. Great transaction will definitely order from vendor again. <br>Thanks Autoplicity.
