Leaf springs are an integral part of your trailer suspension system. The slipper spring is suspended at one end by a hanger that attaches to the eye. The other end slips into a hanger or, in the case of tandem-axle or triple-axle systems, into an equalizer. To determine the type of hangers or hanger kit you need, you must know the specific type of leaf spring you have, as well as your axle diameter and capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications.

Please Note: To ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.

• Choosing Replacement Trailer Suspension Leaf Springs Based on Trailer Axle Capacity
  
• For what is essentially a 6,000 pound axle, you would use 3,000 pound capacity springs, one on each side, to total the 6,000 pounds. Springs that are rated for a 3,000 pound axle would have a capacity of only 1,500 pounds each. For a slipper spring rated for a 6,000 pound axle, we have # E5226. You will need to measure to determine if this spring will fit. The important measurements are on the product page below the description.
