PPE Power 118034100 Features:

Increasing boost is great for horsepower gains, but it places significantly increased stresses on stock components that were not designed to handle them. Such is the case with the stock main bolts.

PPE addresses this common failure point in stock assemblies with this premium PPE Main Stud Kit. This kit is precision-engineered for the real-world of diesel competition, and is an excellent performance upgrade to any Duramax engine rebuild. These studs are thread-rolled to Mil-S-8879 specifications for increased strength and precision centerless ground for accuracy. 

With an independently tested and verified tensile strength of over 231,900 psi, these Studs out-perform even the most venerable manufacturer. 

Kits come complete with hardened parallel washers, nuts, and specially formulated assembly grease for uniform load distribution and accurate torque readings.
