      Description

      Premium Grade Studs for Long‑Term Durability. The studs on this ATS Diesel Performance Diesel Exhaust Manifold Stud and Fastener Set are crafted from 12.9-grade steel, offering a tensile strength exceeding 185,000 psi, making them exceptionally strong and resistant to deformation. Finished in black oxide, they provide enhanced corrosion protection and long-term reliability, even in high-heat environments. ATS Diesel emphasizes that this material is stronger than stainless steel for this application, ensuring a robust and lasting upgrade over factory hardware.

      Designed to Withstand High Clamping Loads & Repeated Heat Cycles. Engineered for heavy-duty diesel performance, this ATS Diesel Performance Diesel Exhaust Manifold Stud and Fastener Set delivers superior clamping force, torqued to approximately 40 ft-lbs, and maintains retention through repeated thermal cycling. This is critical for vehicles that tow, haul, or operate under sustained load, where factory bolts often stretch or fail. The upgraded design helps prevent leaks and maintains a secure manifold seal under extreme conditions.

      Heavy‑Duty Upgrade That Just Makes Sense. If you own an older Cummins-powered RAM, you’re likely familiar with the issues caused by repeated heating and cooling cycles, stretched bolts, cracked manifolds, and exhaust leaks. Upgrading to this ATS Diesel Performance Diesel Exhaust Manifold Stud and Fastener Set provides a solid foundation for a reliable seal, reducing the risk of future failures and improving long-term durability. It’s a smart investment for any serious diesel build.

      Installation. Putting this ATS Diesel Performance Diesel Exhaust Manifold Stud and Fastener Set on your 5.9L I6, 6.7L RAM 2500 takes 1 hour to install.

      Warranty. There is a limited lifetime warranty on this product.

      Application. The ATS Diesel Performance Diesel Exhaust Manifold Stud and Fastener Set fits 1994-2018 5.9L I6, 6.7L RAM 2500 models.
