Sinister Diesel has designed their Heads Up kits to solve one of the most common weaknesses of modern diesel engines: the head bolt. We provide you with a kit that gives you everything you need to replace your factory head bolts with a set up incredibly strong ARP head studs so that you won't encounter any problems as you modify your 5.9L Cummins engine to produce horsepower and torque well beyond the factory levels. From the correct hardware to the right thickness gasket, we'll help you take all the guesswork out of making sure your engine is strong enough to count on.

Complete Head Stud and Gasket Kits for 5.9L Cummins Diesels

This kit is intended to fit the 5.9L Cummins diesel engine and includes the following components:
  • ARP Head Stud Kit (ARP2000)
  • 1.20mm MLS Head Gaskets by Mahle Motorsports
  • Cylinder Head Gasket Kit by Mahle Motorsports

There's a reason that race professionals from NHRA, NASCAR, and Formula 1 have counted on ARP engine hardware for almost 50 years. Each head stud is are cold-forged for uniform internal molecular structure and then it is heat treated for strength before final machining which results in a clamp load rating of 220,000 psi. With such incredible strength, ARP head studs are cheap insurance against the accidental fretting that can cause head gasket failure and the resulting severe engine damage. Each set of ARP studs comes with matched nuts and hardened washers for even clamping force and accurate torque readings during assembly.

Because it's important to use the same thickness head gasket as installed by the factory, this Heads Up kit includes a 1.20mm head gasket made by Mahle Motorsport. These OEM-grade head gaskets are manufactured using multi-layered steel construction with stamped beading around the combustion chambers, and polymers seals for the oil and water passages to prevent leaks due to imperfections in the sealing surfaces on the cylinder head or engine block.

Each Sinister Diesel Heads Up kit also includes a full set of all required gaskets and o-rings to seal every component that attaches to the cylinder head. This includes gaskets for the exhaust manifold, up pipe, upper and lower valve cover, along with valve cover grommets, valve seals, and turbo drain seals.
