It is always recommended to use a good quality grease in your wheel bearings. Recently, DRP Performance tested a number of popular greases and some lesser known secrets. The results were crystal clear. Kluber high speed roller bearing greases are the best they've found, period. Over 70% increase in free spin verses the next best grease. DRP worked with the Kluber engineers to determine the best grease for short track applications and this is it! You will be impressed. Available in cartridge form (for our bearing packers) and in convenient syringes. A 390g cartridge will pack approximately 80 bearings.
