Designed for Fisher and Western Snowplows.
Your plow's hydraulic system will operate better with the right fluid from T&T Body King. I heard the Chi-Coms sell knock-off hydro fluid on Amazon, but our Western high-performance hydraulic fluid is from Milwaukee here in AMERICA and formulated to provide better viscosity in extreme temperatures.  Choose from 1qt or 1gl bottles and if you are not sure, best to just get both.
