Product description

The SVI BH-7231-46Y is a 10-inch Extension Kit engineered for Challenger RJ4.5 series rolling jacks. This set of two extensions provides an additional 10 inches of lifting height, which is critical for safely accessing vehicle frame contact points on high-clearance trucks and fleet vehicles. Designed to replace Challenger part RJ4.5, these extensions feature a precision-fit opening that ensures a stable mechanical connection to the jack arms. Manufactured from heavy-duty structural steel, they are designed to handle the high-load stresses of a 4,500 lb. rolling bridge jack without compromising safety. This kit allows technicians to perform axle and suspension work with the necessary clearance and stability.
