The SBF 289-302 Main Stud Kit 2-Bolt from OPTITORQUE TECHNOLOGIES LLC is designed for builders and enthusiasts who require reliability in high-performance Small Block Ford engines. This fastener kit addresses a critical weak point in factory crankshaft assemblies: the main bearing cap retention. Whether you're building a street engine, weekend racer, or a restoration project with upgraded power levels, this kit is essential for preventing catastrophic crankshaft walk.
This 2-bolt kit is specifically engineered for 289 and 302 cubic-inch SBF applications, utilizing a superior stud-and-nut design that distributes clamping load more uniformly across the main bearing saddle than conventional bolts. The precision-engineered construction ensures consistent torque values and repeatable assembly, which are critical factors when dealing with tight clearances or running higher boost pressures through forced induction. Studs eliminate bolt preload relaxation and reduce the risk of fastener stretch under sustained combustion pressure and inertial forces common in performance engines.
Engine builders, hot rodders, and serious weekend warriors will benefit most from this stud kit when assembling 289-302 blocks destined for sustained RPM or boost. Installation requires standard mechanical knowledge—simply remove factory bolts, install studs into the block, position the main cap, and torque the nuts to specification. This kit is a must-have for anyone looking to enhance the integrity of their engine build.
