SBC Main Stud Kit '67-'97 5.7L LT1/LT4

The SBC Main Stud Kit '67-'97 5.7L LT1/LT4 by PRW Industries is designed for serious small-block Chevy builders who need enhanced engine block security when exceeding stock power limits. This kit is particularly beneficial for those modifying classic muscle cars or building high-performance street engines.

Constructed from premium alloy steel, the main studs are engineered to replace factory bolts that may not withstand high boost pressures or extreme loads. This design minimizes crankshaft walk and block separation during peak combustion events, ensuring reliable performance under stress.

Ideal for applications involving forced induction, high-lift cam packages, or sustained RPMs above 6,500, this kit is compatible with 5.7L LT1 and LT4 engines. It includes all necessary fasteners and hardened washers for proper installation, allowing for repeatable torque values that enhance engine reliability.
