• ARP's oil pump primer kits 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 valvetrain components.
• ARP's rugged primer shafts are rated at 170,000 psi to ensure extended service life.
• They also feature a special billet aluminum sleeve that accurately positions the shaft and keeps it from wobbling.
