The Plow Level-R lets you adjust the back end of your snow plow to the proper height to make the final hook-ups even easier! This simple, easy-to-operate leveling system lets you raise or lower the back of your snow plow from fractions of an inch, to several inches with 1 hand! Once you adjust the Plow Level-R, it keeps the back of your plow at the proper height to match up to the mounting frame on your vehicle each time the plow goes on or off. The Snow Plow Dolly or HEAVY-DUTY Snow Plow Dolly combined with our Plow Level-R is what makes our system truly the best!
