Improve the way your Ford F-150 handles added weight with the PacBrake HP10212 ALPHA HD Rear Air Suspension Kit, designed to provide extra rear suspension support. When carrying heavy loads, the factory suspension can compress and change the truckâs ride height, which may affect how the vehicle feels on the road. This air helper spring system adds adjustable support to help maintain proper suspension position and allows drivers to increase or decrease air pressure based on their load requirements. Constructed with durable double convoluted two-ply rubber air springs, reinforced end caps, and heavy-duty components, the ALPHA HD kit is built to help your truck handle additional weight while maintaining a comfortable ride.
