ARP High Performance Series Connecting Rod Bolt Kits are manufactured from seamless and defect-free 8740 chromoly steel. All ARP rod bolts are heat-treated before grinding and thread rolling and have a large under head radius for greater strength.

ARP Main Bolt Kits are rated at a hefty 180,000 psi tensile strength and they have a wide-area flange to provide even load distribution during torqueing.

ARP Valve Cover Bolt Kits are available in a choice of chromoly steel with a black oxide finish or corrosion-proof polished stainless steel.

ARP Oil Pump Primer Kits are created to let you spin the oil pump with a drill motor and bring up the oil pressure prior to starting the engine. This prevents unnecessary wear or damage to rotating, reciprocating, and valve train components. These products are rated at 170,000 psi to ensure extended service life. They are available with a special billet aluminum sleeve.

ARP High Performance Series Rocker Arm Studs are manufactured from 8740 chromoly steel and are heat-treated to 180,000 psi tensile strength. These products are concentric within .005 T.I.R. thread pitch to thread pitch, which will give you more consistent rocker geometry. With an extra-large radius base, these studs are more resistant to flex and will provide a more positive seating.
