Fits: Chrysler 318 thru 440, Except Hemi
High compression race engines require a stable crank and bottom end assembly. Main studs prevent main cap walk and help support the crankshaft assembly while reducing stress on the block threads during assembly.
Mancini Racing Main Stud Kits are 100% U.S. made, heat treated to 180,000 PSI tensile strength and feature rolled threads and undercut shanks for distributing torque stretch which increases the clamping load. Hi-tensile hex nuts and extra thick chamfered washers are included in each kit
