The Timbren SES suspension upgrade fits the front suspension of Chevrolet
Silverado 1500, 2500, 3500  and GMC Sierra 1500, 2500 & 3500 pickup trucks and
cab chassis. Each laser cut piece of steel is precision bent and powder-coated
to ensure a quality fit. The hollow rubber springs deliver a progressive spring
rate. In other words, the more weight that pushes down on the rubber springs
(weight from a snowplow or heavy aftermarket accessories - such as a steel
bumper) the harder they work to prevent front-end sag.
