    SKU-54613634
    x
                These bearing sets fit all Sprint car front hubs using light weight spindles & all midget hubs.

    Testing shows a good quality tapered wheel bearing provides the lowest rolling resistance when a thrust (side) load is applied, compared to all the popular bearing options. Sprint Cars & Midgets are in constant thrust load. MPD takes quality USA made Timken® bearings and REM® Finish for the ultimate low drag race bearing set.

    MPD recommends NEW Bearing Spacers & TFE Low Drag Seals to be used with these REM® Finished Timken® Tapered Roller bearings. Once adjusted for your hub. You simply lock down your spindle nut for a perfect set of Freewheeling Bearings.

    Use an injection needle to selectively fill the bearing with grease only between the rollers, eliminating overpacking and the resultant overheating that occurs. Properly packed bearings will run cooler, have less rolling resistance and may be packed less often.
    • Provides the lowest rolling resistance when a thrust (side) load is applied
    • Includes Timken bearings and REM finish for the ultimate low drag race bearing set
