The Tusk Drivetrain Oil Change Kit comes with the basic items needed to change the oil in your ATV or UTV's drivetrain. Each kit comes with enough bottles of oil, gear oil, or transmission fluid to change all of the fluids in your drivetrain components. The kit also includes crush washers when needed. Each kit is vehicle specific to ensure you get the correct fluids with enough volume to complete the job. Many OEMs recommend that you change drivetrain fluids as often as engine oil, but this is often overlooked. This kit takes the guesswork out of ordering the essential items needed for your next transmission oil change.
