Description
Factory main bolts are the weakest link in any high-output Small Block Ford engine—they stretch under load, compromise block integrity, and invite catastrophic failure. The ARP SBF Main Stud Kit 154-5407 replaces those marginal fasteners with chromoly studs engineered to handle forced induction, nitrous, and sustained high RPM without yielding. If you’re building a serious engine or protecting an existing investment, these studs are non-negotiable.
