Gator Fasteners Heavy Duty Main Stud Kit – 1982-1997 Chevy/GMC 6.2L and 6.5L Diesel (MSK6265)

Keep the bottom end of your 6.2L or 6.5L GM diesel clamped tight with the Gator Fasteners Heavy Duty Main Stud Kit for 1982-1997 Chevrolet and GMC trucks. Factory main bearing cap bolts can stretch and lose clamping force over time and heat cycles — this kit replaces them with reusable, precision-machined studs that keep the main bearing caps secure and the crankshaft properly supported, especially on engines running higher injection pump fueling or towing regularly.

• Made from HD220 high-strength material rated to 220,000 PSI tensile strength
• Rolled threads after heat treating for maximum fatigue strength and thread integrity
• Precision machined and heat treated for consistent, repeatable torque values
• Complete kit includes studs, washers, and nuts for all main bearing caps
• Fits: 1982-1997 Chevrolet and GMC C/K, Suburban, and van models with the 6.2L or 6.5L diesel engine, including the 1988-1997 GMT400 platform

Mfg Part #: MSK6265. Recommended alongside head studs for any 6.2L/6.5L diesel being rebuilt, towed hard, or built for long-term reliability.
