The Timbren FRTT350F is a Suspension Enhancement System (SES) kit with a set of two Aeon hollow rubber helper springs for the rear of the Ford F-250 and F-350, including the 2005-2016 F-250 and 1999-2016 F-350 Super Duty. As the load increases, the hollow rubber springs push back harder, which cuts sag, sway and body roll when you tow or haul without spoiling the unloaded ride. Rated at 8,000 lb per set, it comes with helper springs, brackets and hardware; total load must still stay within the vehicle's gross weight rating.
