This is a Nitro Engine Rear bearing sized 13x25x6mm. This Bearing utilises the same PA46 Retainer as our Ceramic Bearings, but has Steel Balls. Plaig Bearings are a stronger, more reliable bearing with greater heat resistance and superior life to the standard factory bearings. We stock all other sizes of bearings for RC Cars and also sell Complete Bearing Kits for many popular brands of vehicles. If you can’t find the correct bearing by size or part number please Contact Us .
