The cush hub (sprocket carrier) bearing leads a tough life. This is especially true if your cush rubbers get old and soft. They can allow the chain to pull the cush hub sideways putting a twisting load on the bearing. If there's any question about the condition of your bearing replace it now with this double sealed bearing and quality seal.

This kit will replace your stock sprocket bolts, nuts and keepers with new hardware.

Many aftermarket sprockets are thinner where they bolt to the wheel and the threads on the stock bolts do not allow these sprockets to be tightened down all the way. These grade 10.9 bolts will alleviate that problem. They are the same length as the stock ones, but the threaded area is longer allowing stock sprockets or aftermarket sprockets to be securely tightened down.

The bolt keepers are genuine Yamaha replacement parts to ensure an accurate fit. It's a perfect upgrade if your keepers have been removed too many times.

A set of three OEM Suzuki front sprocket bolts. Thread-lock compound has already been applied for extra security.

• Six class 10.9 steel sprocket bolts with matching factory-style metal locking Fuji nuts
• Each sprocket bolt has medium-strength threadlock patches for a double lock
• Includes Allen key insert that adapts 8mm T-handle or socket to proper Allen key size for easy installation and removal
• PART #2401-0941 is made to match stock CRF sprocket hardware with 14mm nuts but will work with most Japanese models

A set of two OEM Yamaha front sprocket bolts with one OEM Yamaha retainer plate. 

This new unit from JNS will protect your cases from the damage caused by a thrown chain, and will also keep your pants, boots or foot safe from your countershaft sprocket.

The case saver portion is laser cut from 0.25" aluminum and then has the 0.19" aluminum countershaft sprocket cover welded to it and the entire unit is powder coated black.

All the mounting hardware is stainless steel with machined aluminum spacers also included.

If you have a 16t front sprocket, mounting modification may be needed to fit. Install the case saver on the bike without the top spacer and bolt. This provides a little extra wiggle room. Add the top spacer and bolt after the bottom bolts are loosely threaded.

JT Sprockets is the world's leading manufacturer of aftermarket sprockets, constantly raising the industry's standards for quality and service. JT Sprockets are the only sprocket manufacturer using the ultra-durable high carbon C49 steel for rear sprockets.

JT steel rear sprockets are manufactured using only the finest grade of C49 high carbon steel.

Two styles of rear sprocket were used on the DR350. The 90-95 'S' and 'SE' (street legal) models have a cush drive hub. The 96-99 'S' and 'SE' as well as all of the 'dirt only' models have a non-cush rear hub. Select your sprocket accordingly. If you are not sure, look at your bike. If the sprocket is bolted directly to the wheel hub you have a non-cush model. If your sprocket is bolted to a separate sprocket carrier you have a cush drive model.
