This is a must have for anyone who has noticed that the original seat position is TOO HIGH in the cab. These brackets correct the line of sight through your windshield, pedal angles, seating position and overall comfort-ability of the stock bench seat. We've designed these brackets to solve all of these issues with minimal install time and effort. These brackets will lower the seat approximately 2 inches. It was necessary to eliminate the factory sliding function in order to get the desired drop, so BROTHERS corrected this by adding slotted mounting holes to allow 1-1/4" fore and aft adjust ability. You're going to love the extra room this custom bracket set gives you!
