FAQ
Why billet hold downs over stock?Billet, heat-treated steel paired with ARP bolts provides higher clamp stability, helping prevent injector movement and sealing issues under performance use.
Do these fit LB7 (2001-2004)?No. Use the LB7-specific kit PDM-08377.
What torque should I use?Torque ARP bolts to 28 ft-lb with ARP lube (follow a consistent sequence). Re-check after heat cycles on fresh builds.
What should I replace during the job?Consider new injector seals/O-rings and inspect injector cups (LB7), rail fittings, and return line seals to prevent future leaks.
