ARP 82.0mm Ring Compressor

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 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...

Shop Fabrication Parts & Materials at Black Ops Auto Works for stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, V-band clamps, flanges, merge collectors, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, welding supplies, brackets, bungs, and hardware for building custom exhaust systems, turbo plumbing, intercooler piping, fuel systems, and engine bay routing. Start with tubing (304 or 321 stainless, titanium, or aluminum) in the right diameter and wall thickness, then add mandrel bends, flanges, V-bands, and clamps to complete the joint work. AN plumbing follows the same pattern: match dash size to horsepower target, pair the right hose (PTFE or CPE) with matching hose ends, and use adapters, bulkheads, and distribution blocks to route fuel, oil, and coolant cleanly. Shop by material (stainless, titanium, aluminum), fitting type (AN, ORB, NPT), diameter, or brand (Vibrant, Ticon, Stainless Bros, Radium, Fragola, DEI, ATP). ...
