Main Stud Kits

Note: These special studs are available in Chevy Main Stud Kits. They permit easy mounting of O.E.M. or aftermarket windage trays.

In a race engine the main bearing caps are subjected to loads much greater than those encountered in passenger car applications. As RPM and cylinder pressures increase, so does the need for a stable crankshaft support. Engine builders have known for a long time that coarse threaded bolts are not the ideal fastener in this environment. Studs are the preferred method of clamping the main bearing caps to the block to help prevent cap walk and chatter.Like our head studs, B&B Main Studs are constructed from top quality 8740 chrome-moly steel. Rigid quality control standards insure you of precision rolled threads and a stud which is centerless ground, after heat-treating, to remove all surface irregularities. All main cap stud kits contain black oxidized studs, heat-treated alloy nuts, and parallel ground, heat-treated washers.
