The Timbren Suspension Enhancement System for Ford F-650 and F-750 front suspensions is an auxiliary rubber-spring upgrade that prevents front-end sag caused by heavy accessories or plows. Each precision-bent, powder-coated steel component and hollow rubber spring provides a progressive response: the more weight applied, the firmer the support. The kit bolts on, needs no airlines, and helps keep the vehicle level while towing or hauling.
