  • One of the best ways to keep your kart competitive is to keep all the bearings free spinning and clean -- a very easy and economical way is to use a rear axle bearing with removable covers. Bearing covers have been around for a while and are used in other industrial applications.

    These are the OEM RBI extra free spinning premium oil filled bearings. We have removed hub side shield and seal and reassembled the bearings with the proper covers to eliminate fit and drag problems. Lock bearings to axle or positioned so that button head bolts only locks the covers, allowing bearing to float on axle shaft.

    There’s much conversation about more expensive exotic type bearings and materials, but the bottom line is you need to start a good maintenance program before spending that extra money.

    Bearing maintenance after a race weekend consist of removing covers, cleaning, flushing clear of dirt and debris using an aerosol brake or carburetor cleaner. Once flushed with cleaner, continue flushing bearing with some compressed air and a light weight lubricant such as WD-40. We recommend a final lubricant like Tri-Flow.

    For those of you new to the sport look at your back axle carefully, spin it and be sure it rolls free -- don’t forget your clutch and chain have a big part in how freely your rear axle rolls. Replace the chain if it’s been on longer than a season. Sometimes drag can be as simple as having your chain too tight.
