Overview
Replace worn or gritty bearings in your HPI VectR4 with this genuine HPI 4x8x2.5mm ball bearing pair. Fresh bearings help the drivetrain spin freely so more of the motor's power reaches the wheels.
Rally cars spend a lot of time on dust, gravel and dirt, and bearings are among the first parts to wear. Keeping spares on hand makes routine maintenance quick and keeps the car running smoothly.
