Genuine Honda 42240-HN8-305 Rear Driveshaft CV Boot Set
Torn or cracked boots on your Rincon's rear axle? Once the boot splits, grease flings out and grit grinds the joint to scrap — and a whole new driveshaft is a lot more expensive than a set of rubber. This is the factory Honda boot set for the rear driveshaft on the FourTrax Rincon and Rubicon 700, sold as a matched pair with one boot for each side, plus the OEM grease and bands to do the job properly.
This is the real Honda part, not a thin aftermarket copy. Same compound, same fit, same service life as what came on the machine at the factory.

Why Genuine Honda
- Molded to factory dimensions — seats on the joint and clamps down without stretching or pinching
- OEM rubber compound resists the heat, mud, and UV that destroy cheap boots in a season
- Correct grease included — the wrong grease breaks down and cooks the joint
- No trimming, no "universal" fitment guesswork
Installation Notes
- Best done with the rear driveshaft removed and the joint cleaned of old grease and debris
- Inspect the joint for pitting or play while the boot is off — a boot set won't fix an already-worn joint
- Pack the joint fully with the supplied grease before clamping
- Seat bands evenly and confirm the boot is not twisted before the machine goes back on the ground
- Pair with our dust seals and knuckle bearings if you're already into the rear end
- Torque specs and service intervals: see your Honda service manual for your exact model year
