Another first from the Modular Innovators at MMR!

This bolt on system replaces the factory multi-piece rear thrust bearing completely. This system requires a external oil pump such as the new MMR Billet external pump or other external oil pump. This system virtually eliminates all thrust bearing failures and reduces friction so much on automatic equipped vehicles that turbo's will spool faster on the foot brake and the transbrake! Bolts directly to the factory oil pump location and uses precision Needle Roller Thrust bearings designed to handle over 300lbs of forward and rearward thrust!  No Modification needed for install, works with all Modular Blocks. As used by the MMR 2000HP Twin Turbo racecar!
