2006-2016 Duramax LBZ/LMM/LML/L5P PPE Main Stud Kit (118034100)
These main cap bolts are essential for keeping your crankshaft in line and maintaining proper seals at the main bearing caps. Stock main cap bolts can easily give out in performance applications or even under everyday stress, resulting in major engine trouble. That's why the PPE Main Stud Kit is the perfect solution for addressing this all-too-common issue.
Constructed from top-of-the-line chrome-moly alloy, the PPE Main Studs boast impressive 215,000 PSI yield strength and 230,000 PSI tensile strength. Before being centerless ground and thread rolled, each stud undergoes heat treatment to reduce stress concentration and increase fatigue resistance. For ultimate precision, the studs are expertly broached via EDM. Complete with a sleek black oxide finish, both the studs and nuts are sure to impress.
The kit comes complete with assembly lubricant packet for uniform load distribution and accurate torque readings.
- High performance chrome-moly alloy
- Verified 230,000+ psi tensile strength
