Boss Bearing 42-1028B Lower Ball Joint Kit for Yamaha

The Yamaha Bear Tracker, Big Bear, and Bruin 250 are beloved utility ATVs that built their reputations on dependability and toughness — and the Boss Bearing 42-1028B lower ball joint kit is built to keep them earning that reputation for years to come. Precision-engineered to meet or exceed OEM specifications for a direct drop-in fit on the Bear Tracker 250 YFM250X from 1999 through 2004, the Big Bear 250 YFM250B from 2007 through 2009, and the Bruin 250 YFM250B from 2005 through 2006, this kit restores stable, confident front suspension performance and eliminates the vague steering and loose front end feel that worn lower ball joints cause. Finding quality suspension components for Yamaha utility ATVs from this era can be a challenge — the 42-1028B takes the guesswork out and gives you the reliable, properly spec'd lower ball joint solution your machine deserves.
