DP Engine Parts also offers ARP rod bolts as an alternative to our own tool steel and stainless steel billet rod bolts, available in three material grades to match the requirements of your build.
ARP2000
ARP2000 is an alloy steel that can be safely heat-treated to higher strength levels than standard 8740 chrome moly, delivering a clamp load rated at 220,000 psi. Widely used in short track and drag racing as an upgrade over 8740 chrome moly, in both steel and aluminum connecting rods.
- Clamp load rated at 220,000 psi
- Heat-treated alloy steel, stronger than 8740 chrome moly
- Precision rolled threads for maximum fatigue life
- Suitable for short track and drag racing applications
ARP L19
ARP L19 is a premium steel processed for superior strength and fatigue properties, delivering a clamp load rated at 260,000 psi. Used primarily in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000.
- Clamp load rated at 260,000 psi
- Premium steel with superior fatigue resistance
- Precision rolled threads for maximum fatigue life
- Recommended for extreme inertia loads beyond ARP2000
ARP Custom Age 625+
Custom Age 625+ is a super-alloy offering superior fatigue cycle life, tensile strength, and toughness, with tensile strength of 280,000 psi and complete atmospheric corrosion and oxidation resistance.
- Tensile strength 280,000 psi
- Super-alloy with complete corrosion and oxidation resistance
- Superior fatigue cycle life and toughness
- Top-tier rod bolt option
