Losi LOSA6937 5x10mm Shielded Ball Bearing (2) XXL-2 8ight-X 8ight XT / XTE

The Losi LOSA6937 is a pair of 5x10mm shielded ball bearings built for the XXL-2, 8IGHT-X, and 8IGHT XT/XTE. Shielded bearings offer a lighter-duty seal than fully sealed bearings, keeping out larger debris while maintaining smooth, low-friction rotation in areas that see less exposure to dirt and moisture than wheel or axle bearings.

This size shows up in specific drivetrain and suspension pivot points on these platforms, and a worn bearing here can introduce play or added rolling resistance that saps a small amount of performance from an otherwise well-tuned car. Bearings are consumable parts on any RC vehicle that sees regular track time, and replacing them as a pair keeps rotational resistance balanced on both sides of whatever assembly they support. This genuine Losi pair matches the factory 5x10mm specification, so they drop into your existing bearing bores without any modification. Keep spares on hand for routine maintenance.
