The Strongest and Lightest Sprocket Bolts Available! This kit includes six class 10.9 zinc plated steel sprocket bolts with factory style metal-locking or "Fuji" nuts. Each sprocket bolt has medium strength threadlock patches applied for a double-lock. Threadlock liquifies and anaerobically seals when the bolt is tightened. This kit also includes an 8mm tool insert for socket wrenches. Fits all Japanese and most European dirt bikes.
Important installation information Hub-Savers are the strongest, most complete sprocket fasteners available and have been developed and tested at the professional level in both motocross and off-road applications. Sprocket bolts are a critical fastener and must be installed properly to ensure your safety and to avoid damaging your machine. To insure long and reliable use of these quality fasteners:
•First clean and inspect your hub. If the hub is damaged or if the mounting holes are oval, the hub must be replaced.
•Use the included Allen insert in an 8mm socket wrench to install the sprocket bolts. If your motorcycle uses washers behind the nut, you must re-install the washers.
•Refer to your owner’s manual for the proper torque (typically 25-35 ft lbs), take the torque reading on the nut side. Never over-tighten sprocket bolts!
•Use a permanent marker to make an aligning mark on the nut and hub. Inspect this mark periodically to insure the nut is maintaining torque. If your sprocket bolts become loose, they must be replaced! Sprocket bolts become loose only under extreme stress, an indication that either they were installed improperly or there is a problem with the drive line. Check the drive line for bent chain guides, bad wheel alignment, damaged mounting holes on the hub, etc. Properly tightened sprocket bolts on properly functioning drive lines will remain tight indefinitely.
