The Bumper Lift is designed to fit most slotted or curved bumpers, for quick and easy lifting. Bumper Lift has a 3,000 lb. capacity (1361 kg). When used with the Hi-Lift Jack, which is not itself designed to be used on curved or tubular bumpers, the Bumper Lift makes raising one wheel of most average sized vehicles up to 2" (5 cm) above the ground an easy task. Never attempt to lift more than one wheel at a time.
