Boss Bearing 41-3557B Ball Joint Kit Kawasaki KLF300 Bayou 86-05

The Kawasaki Bayou 300 is one of the most beloved and longest-running ATVs ever produced, earning a reputation for toughness and dependability that spans nearly two decades of production. The Boss Bearing 41-3557B ball joint kit is precision-engineered to meet or exceed OEM specifications, delivering a direct drop-in fit for both upper and lower positions that restores the stable, confident handling your Bayou was built to provide. Worn ball joints cause vague steering, uneven tire wear, and a front end that feels loose and unpredictable on the trail — the 41-3557B fixes that with a single kit that covers both positions on compatible KLF300A and KLF300B models. Whether you're restoring a classic or keeping a hardworking Bayou in top condition, this is the complete ball joint solution built to match the legendary reliability these machines are known for.
