The Atlas XHP-9K-SLARM Sliding Arm Adapters provide added flexibility for positioning lift pads on two post vehicle lifts. Designed to slide along the length of the rear arms, they help reach a wider variety of lifting points on different vehicles. Compatible with many Atlas asymmetric arm lifts, including the Atlas 9KOH, they may also fit select other brands. Each adapter is built from high grade materials for durability in professional or DIY environments. Sold as a pair, the adapters measure approximately 10 by 5 by 3 inches and install easily onto existing lift arms.
