Chevy Head Stud Kit '97-'03 4.8/5.3/5.7/6.0L

PRW uses premium grade 4140 Alloy Steel. Their studs are specially heat-treated to 200,000 psi. This heat treating procedure allows for total heat penetration, resulting in a stronger, more superior stud compared to lesser quality studs from other manufacturers. To ensure perfect alignment with gaskets and cylinder heads, PRW studs are centerless ground after being heat treated, leading to remarkably straight and concentric studs. PRW studs are then thread rolled, which assures better fatigue strength than having this process done before heat treatment. This manufacturing process may cost more but the results are well worth the extra effort. PRW also offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force and compensates for head gasket compression when cylinder heads are installed. This helps prevent blown head gaskets and assures optimum engine sealing! Premium quality heat-treated 4135 chrome moly steel head stud kits are available for most every domestic and import application. Comes with PRW CMD Extreme Pressure Assembly Lube (0.5oz Packet).
