"Bumper damage will be a thing of the past with these 8’ Lay-Over Auto Hoist Ramp Extensions. Designed to be placed over existing car lift ramps to lessen the angle of approach, these ramp extensions reduce the ramp approach angle so that low-profile vehicles or sports cars such as Corvettes, Vipers, Mustangs and others can be safely driven up for service, maintenance or repairs. Manufactured from lightweight, high-strength aluminum, each ramp extension measures 8' L x 15"" W and can support up to 5,000 lbs. per axle. The knife-cut top and bottom ends ensure precise, smooth transitions as you drive the vehicle up, and the serrated rungs grip tires while loading for maximum traction. These extensions are sold in pairs."
