      Heavy-Duty Hardware for Leak-Free Exhaust Sealing. The PPE Exhaust Manifold Stud and Nut Kit for OEM Manifolds; 2017–2026 6.6L Duramax Silverado 3500 HD replaces worn factory hardware with high-strength studs engineered to keep exhaust manifolds clamped tight.

      High-Strength Materials Built for Duramax Temperatures. Constructed from premium alloy, the PPE Exhaust Manifold Stud and Nut Kit; 2017–2026 Silverado 3500 HD resists stretching, corrosion, and fatigue far better than stock fasteners.
