This thread is made for anyone whos has a Lsr Swingarm with Lsr Carrier or just Lsr carrier .If you have either this will be helpful.After search for about 4 hours last night and coming up with nothing. Not much info on them.The Lsr carrier uses different bearings then the stock cariiers.if you put the stock lt250r bearings in they will not last.Also your taking a chance on messing up your axle,from the bearing sticking on the axle shaft eating the axle up.I have made this mistake and i hope this helps anyone to not go threw what ive been threw. Thier part number is #32103 This goes for the lt500r too thier part number is #33103. Their just no info on these.
