Milodon's rocker arm stud kits are premium race quality fasteners. Manufactured from tough 8740 steel, they feature a large ground radius fillet to provide increased support to the stud shank, effectively eliminating bending and subsequent breakage. All Milodon studs are precision machined with rolled threads and heat-treated for strength of 190,000 PSI. The complete stud has a black oxide finish, and each kit contains 16 studs.
