Ensure maximum crankshaft stability and bottom-end strength with this LS Main Bolt and Stud Kit, designed as a direct replacement for factory LS main bolts while also incorporating main studs for additional reinforcement. Over time, factory main bolts can weaken, stretch, or lose clamping force, leading to bearing misalignment, crankshaft instability, and potential engine failure. This complete bolt and stud kit restores factory torque specs, ensuring a solid and secure foundation for high-performance LS engine builds. The main studs in this kit help to increase overall block stability, reducing main cap walk and improving load distribution across the crankshaft main journals. This added reinforcement is particularly beneficial for high-RPM, turbocharged, and supercharged LS applications. Made from high-strength steel, these fasteners are engineered to withstand extreme loads, high-RPM stress, and heat, making them perfect for factory rebuilds, LS swaps, and forced induction applications. Whether you're refreshing a stock bottom-end or assembling a high-horsepower LS build, this main bolt and stud kit provides the reliability and durability needed for peak performance.
