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 where necessary. Each kit is vehicle specific to ensure you get the correct fluids with enough volume to complete the job. Many OE manufacturers recommend you change the Drivetrain fluids as often as the motor oil, but this is often overlooked. This kit takes the guess work out of ordering the essential items needed for your next drivetrain oil change.
