Boss Bearing Combo Both Upper or Lower Ball Joint Heavy Duty Steel

The Boss Bearing 42-1015C ball joint two-pack is the smart, cost-effective solution for Honda ATV and Pioneer side-by-side owners who want to do the front suspension job completely the first time. Containing two precision-engineered ball joints built to the identical OEM-matching specifications as the single-unit 42-1015B, this two-pack can be configured as one upper and one lower for a complete one-side front end rebuild or two of the same position to service both sides at once — all at a better value than buying two individual kits.

The lower position covers the TRX420 Rancher IRS and Solid Axle from 2014 through 2026, TRX450 series from 1998, the full TRX500 Foreman and Rubicon lineup including IRS and Solid Axle variants, the TRX520 series from 2020 through 2026, the TRX650 and TRX680 Rincon, and the TRX700 Rubicon from 2024 through 2026. The upper position extends that coverage significantly — adding the full Honda Pioneer 500, 520, 700, 700-4, 1000, and 1000-5 side-by-side lineup from 2015 through 2026, TRX350 Rancher models from 2000 through 2006, TRX400 Rancher 4x4 from 2004 through 2007, and TRX420 models starting from 2007 rather than 2014.
