This is an EXTREME DUTY VR6 head stud kit! When running over 35PSI we highly recommend this kit!
Exact tolerances ensure that gaskets and cylinder heads just glide into position and align perfectly. ARP Head Studs are available with 5/8″ drive 12-point nuts. These head studs are manufactured by ARP from premium 8740 chrome moly steel and heat treated to 190,000 psi. They are thread rolled after the heat treating process, which vastly improves their fatigue tolerance compared to studs threaded before heat treatment. High-quality, parallel ground washers included.
A SDM exclusive! This kit has been assembled specifically for the 3.2L VR6 and will require head and block machining. Speed Density Motorsports offer machining of these components for $500 plus freight. Please email us for this service.
