Timbren GMRW55 Suspension Enhancement System for 00-08 Gmc W5500hd Forward/Chevrolet W5500hd Tiltmaster, 98-08 Gmc W4500/W3500 Forward, 98-09 Chevrolet W4500/W3500 Tiltmaster, 88-10 Isuzu FSR

This SES Suspension Upgrade can be adapted to fit the rear suspension of most Chevrolet Tiltmaster Series & GMC Forward Series medium & heavy-duty trucks equipped with leaf springs (see below for full list of applications). Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. We€™ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag, and help stabilize the load.

This kit is rated at 15,000 lbs capacity. Even though you€™re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
