Milodon aftermarket main bearing caps not only strengthen factory 2-bolt blocks, but they will also add a measurable degree of strength to 4-bolt blocks. They are made from precision-machined, high-strength steel, which has the proper balance of strength and flexibility to allow for the transfer of increased shock loads to the crank and bearings. The secret is in the side bolts. They are angled so that they pull from the side walls of the block and not from the flimsy main web area. They'll also load the cap against the register step, which will prevent dreaded "cap walk." They can be installed by anyone with a hand drill and a tap and they come with the necessary bolts, washers, and drill bushing to complete the installation. Milodon main cap kits are available in your choice of angled or straight bolts.

Wagner Tuning Pro Series main stud kits are must-haves for all engines that run with increased boost pressures. They replace the original main bearing bolts with high-strength Pro Series 18.8 stud bolts with a tensile strength of 1850 N/mm², and they do not need to be replaced after disassembly, but can be reused. Pro Series bolt threads are formed and not cut as is customary in the trade. By rolling the threads, the strength of the tooth flanks can be increased by around 30 percent. All Pro-Series products are supplied with a nickel coating or a burnished finish and are therefore protected against corrosion in the long term, even under the toughest conditions. Pro Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Thanks to a cone on the engine block side of the stud, these are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in the engine block. This support protects the threads during frequent assembly of racing engines. Nuts and washers are included in each set, and they also have a tensile strength of 1850 N/mm². Select the kit designed for your vehicle in the finish you prefer best.
