Boss Bearing 42-1033B Ball Joint Kit Kawasaki Brute Force Mule PRO Teryx

The Boss Bearing 42-1033B ball joint kit is one of the most comprehensive Kawasaki front suspension solutions available — covering an extensive range of sport ATVs, utility ATVs, Mule PRO utility UTVs, Ridge UTVs, and Teryx sport UTVs in both upper and lower positions from 2002 through 2026. The lower position covers the full lineup including KFX450R, KFX700 V-Force, KVF360 Prairie, KVF650 Prairie and Brute Force, KVF700 Prairie, KVF750 Brute Force EPS, the complete Mule PRO-DX, DXT, FX, FXR, FXT, and MX lineup, the full Ridge UTV family, and Teryx 750 and 800 series. The upper position covers the same range with the exception of the KVF360 Prairie, KVF650 Prairie, KVF700 Prairie, and KVF650 Brute Force models which are lower only. Precision-engineered to meet or exceed OEM specifications for a direct drop-in fit, this kit restores stable, confident front suspension performance across every application it covers — from the hard-charging KFX450R to the hardworking Mule PRO-FXT and the trail-ready Teryx 4x4 800 S.
