Hot Rods – Transmission & Engine Bearings, including transmission bearing kits for the 87-06 Yamaha Banshee 350, the 06-14 Honda TRX 450ER and 06-09 TRX 450R, the 06-09 Suzuki LT-R 450 and the 01-05 Yamaha Raptor 660, plus the output shaft kit for that same 660cc Raptor. These sets cover the bearings that support the shift shafts, countershaft and output shaft inside an ATV gearbox, and they come as complete kits so every bearing in the case gets replaced at once rather than one at a time. Gearbox bearings take a beating in quad use: clutch dumps, gear changes under full load, and mud and water that find their way past seals. Once they develop play the shafts wander, gear teeth load on their edges, and shift forks and dogs start chewing themselves up. Installing new ATV transmission bearing kits restores shaft position, so gears mesh across the full tooth face, shifts land crisply without that hunt between gears, and second gear stops popping out mid-corner when you are on the pipe. Give us your year, model and engine displacement and we will verify the right bearing kit for your machine before you order.
