Timbren URMDH Suspension Enhancement System for 16-21 Ford F750HD/F750/F650HD/F650, 08-21 Western Star 4700 SF/SB, 99-04 Freightliner FC70, 88-21 Isuzu Reach/Nrr/Nqr/Npr-Xd/Npr-Hd/Npr

This SES Suspension Upgrade can be adapted to fit the rear suspension of most heavy-duty trucks equipped with either leaf or air springs. 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 16,000 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.

• Eliminate Vehicle Squatting & Sagging
• Cushion Road Shocks
• Improve Handling
• Satisfaction Guarantee
• Lifetime Warranty
