LS1, LS6, LQ4, LQ9, LR4, LM7, L59, LM4. 4.8, 5.3, 5.7, 6.0. These head studs are manufactured by ARP from premium 8740 chrome moly steel and heat treated to 200,000 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 and 6pt Hex nuts included. Exact tolerances ensure that gaskets and cylinder heads just glide into position and align perfectly. Be sure to note which head bolts you need as GM used two different style LS head bolts.
