This Ultra High-Speed Premium Rebuild Kit #4 is for Vortech® V3 SL trim Superchargers. It includes the best of everything. A pair of our top-of-the-line ceramic 72,000 rpm bearings for your impeller, our better-than-stock mechanical face seal, a set of new HSS input shaft bearings, and an input shaft seal too. The 928 Motorsports High-Speed Ceramic Bearings: We have found the right combination of ceramic ball bearings, HHS bearings races, and high-temp phenolic bearings cages to allow safe increases in rpm's compared to stock Vortech® impeller bearings. Previously, the operational limits for the stock bearings on the superchargers listed above was 53,000 rpm. Our Premium High-Speed Ceramic bearings are rated at 72,000 rpm in oil, and can run in the high 60,000's* all day. Accept no substitute! If you think your going to spin up your Vortech® a little faster for more boost - these are the bearings you need. The 928 Motorsports Premium High-Speed Seal: Our seal is made from the finest materials for a long life, plus it has a broader sealing range than the OEM seal, so leaks don't happen! Complete rebuild kit includes: 2 matched Timken ceramic high-speed bearings 2 HSS input shaft bearings 1 Premium High-Speed Mechanical Seal 1 PTFE-coated Viton input shaft seal * NOTE: confirm that the other supercharger internals (input bearings and the impeller) can also be safely operated at your planned impeller speed.
