ARP SB Chevy 6.2L LT1 SS 12PT Header Stud Kit

ARP, short for Automotive Racing Products, was founded in 1968 in Ventura, California, and its range here is fasteners for engines and drivelines. The kits cover cylinder heads (head studs and head bolts), main bearing caps and connecting rods. Others are for flywheels and pressure plates, intake and exhaust manifolds, water pumps and fans, and pulleys and accessory brackets. Alongside them sits a large section of individual bolts, nuts and washers sold by thread, length, head type and finish, plus tools such as piston ring compressors and thread chasers.

The listings name the material where it matters: 8740 chrome moly and ARP2000 most often, with L19, Custom Age 625+, Inconel and stainless steel for particular kits. They also give the head type: 12-point or hex.

Most kits carry the engine name in the title instead of a vehicle listing, so check the engine code rather than the car. Only a few ARP kits are also listed by car, mostly for Honda, Nissan and Toyota models.

Where the other engine brands on TrackToolFactory supply pistons, bearings, gaskets and valvetrain parts, ARP supplies the studs and bolts that hold those parts in place.
