HMR HD L19 12mm Head stud kit for the 1989-1998 Dodge 5.9L 12 Valve Cummins Turbo Diesel

Recommended for applications exceeding 80 psi or small twin turbos producing not more than 80 psi.

The head bolt holes in the Cummins blocks are not tapped to the bottom.  Haisleys has designed these studs with more threads for less stress to the block as well as the stud.

12mm L19 material

Hex broach for easy installation

HD washer and 12pt hardened nut

Assembly lube

Instructions

Same great Haisley Machine Design, now manufactured by ARP.
