ARP EJ20/25 CASE BOLTS (260-5401)

When rebuilding an engine, there are several stock parts you wont want to reuse. Stock case bolts stretch over time, and even more so each time they are re-tightened. Each time they stretch, their clamping abiltiy decreases. If case bolts stretch, bearings can spin, and possibly even worse. Case bolts are a low cost item that can mean the difference between your engine lasting, or not. Use ARP Case Bolts for your engine build.
Far superior to any other main bolt kit offered for use in competition engines. ARP main bolts are designed to meet the exacting standards and demands of professional engine builders.
