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