This Timbren SES suspension upgrade fits underslung-axle trailer suspensions with 2-3/8 in. to 3 in. diameter axles and 2 in. wide leaf springs, offering a 5,000 lb capacity. Laser-cut, powder-coated steel brackets and hollow rubber springs provide a progressive spring rate that resists sag and stabilizes loads. The bolt-on installation uses basic tools, requires no airlines, and improves handling while not changing the trailer’s gross trailer weight rating.
