All Balls gearbox secondary shaft seal kit on front sprocket side for KTM 300 EXC 17-18

Kit includes case hardened bushing, replacement outer seal along with any o-rings, snap rings or lock washers required to complete the repair.

Each All Balls kit contains all the necessary components (bearings, seals, pins, spacers, collars, thrust washers and thrust bearings) needed to finish the job without ordering a laundry list of parts. Better yet, all All Balls kits meet or exceed the quality of the OEM parts they replace and at a fraction of the cost.
