Product Details

The ARP 134-6411 is a high-performance connecting rod bolt kit featuring Wave-Loc technology and 8740 chrome moly construction. This 2-piece fastener set delivers the reliability and strength that racing professionals demand for high-stress engine applications.

Wave-Loc Technology Benefits:

  • Wave-Loc surface contacts rod and cap for optimal alignment and reduced fluctuating stress
  • Provides interference fit of .001 to .005 inches to accommodate wide range of OEM rod bolt hole tolerances
  • Superior material grain flow compared to knurled bolts which have stress-inducing sharp edges
  • Eliminates galling and scoring through smooth surface contact without digging
  • Strengthens the connecting rod itself by reducing stress concentrations

ARP Quality Features:

  • Forged in-house using premium quality materials for consistent performance
  • Heat-treated on special vertical racks ensuring complete 360-degree penetration
  • Threads rolled after heat-treat providing up to 10 times longer fatigue life
  • Precision CNC-machined to exacting specifications
  • ARP name stamped on each bolt as assurance of quality

8740 Chrome Moly Material: This proven alloy delivers tensile strengths between 180,000 and 210,000 psi, making it ideal for most racing applications. The material offers excellent toughness with adequate fatigue properties when threads are rolled after heat treatment. Chrome moly is a reliable, cost-effective solution for engines where bolt strength appropriately matches anticipated loads with proper safety margins.

Important: Monitor bolt stretch regularly and replace when permanent elongation reaches .0005 inches to maintain optimal performance and safety.

Found Autoplicity through price searching. Best price, easy to navigate site, quick service. Bookedmarked for future use!

An easy to navigate website, great prices and efficient company. I will definitely check Autoplicity first for all of my automotive needs. From purchase to arrival I was well informed as to the status of my order.

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Very easy. Tried O'Reilly's and that was a pain. I'm ordering from Australia.

great prices,fast shipping,cheaper than discount warehouse
