ARP
ARP (Automotive Racing Products) is the world’s premier manufacturer of high-strength engine and driveline fasteners—head studs and bolts, main studs, rod bolts, and more—engineered and manufactured in-house from start to finish for race-proven reliability. With vertically integrated processes that include cold heading, machining, heat-treating, thread rolling after heat treat, and rigorous QA, ARP maintains aerospace-level certifications (ISO 9001 and AS9100) and validates every part for repeatable clamp load and fatigue resistance. Signature alloys such as 8740 chromoly, ARP2000, L19, and Custom Age 625+ deliver ultimate tensile strengths up to the super-alloy range, while ARP Ultra-Torque fastener assembly lubricant helps achieve consistent pre-load during installation. From street performance builds to professional motorsport programs, ARP fasteners provide precise fitment, superior metallurgy, and the durability needed to keep engines together at elevated cylinder pressures and...

ARP Head Studs
ARP head studs replace factory head bolts with precision-machined threaded studs that provide more consistent and repeatable clamping force on the cylinder head gasket. Unlike head bolts that apply torque through both rotational and tensile forces, head studs allow the nut to be torqued concentrically on a stud that is already stationary, producing more even clamping load across the entire head gasket surface. Popular ARP Head Stud Applications ARP head studs are available for a wide range of performance and turbocharged engines including the Subaru EJ series, Honda K series and B series, Mitsubishi 4G63 and 4B11, Honda Civic and Integra, Toyota 2JZ-GTE, Nissan SR20DET and RB series, GM LS series, Ford Coyote and 5.0, and Dodge/Chrysler HEMI applications. ARP offers both 8740 chromoly and ARP2000 alloy head stud kits, with the ARP2000 material providing approximately 20 percent higher tensile strength for high-boost applications above 30 psi. Why are head studs preferred over head b...

Connecting Rods & Push Rods
Connecting rods and push rods are critical internal engine components that transmit force within the combustion cycle. Connecting rods link the piston to the crankshaft, while push rods in overhead-valve engines transfer cam lobe motion upward to the rocker arms and valves. Upgrading both types with forged steel or chromoly alloy components increases durability and allows an engine to handle sustained high-RPM or high-boost operation.Popular UpgradesForged 4340 chromoly H-beam connecting rods are the standard upgrade for any performance engine build targeting more than 400 horsepower, replacing the cast or powdered-metal OEM rods that cannot survive the fatigue cycles of performance use. Performance push rods in hardened chromoly with specific wall thickness and length specifications are essential for LS and small-block Chevy builds where custom camshafts alter valve train geometry. Matched sets in the correct length and diameter simplify assembly and ensure consistent valve train g...
