Product Description

The Timbren FRTT350F Severe Service Rear Suspension Enhancement System delivers maximum stability for your 2005-2016 Ford F-250 or F-350 Super Duty when hauling top-heavy loads like slide-in truck campers or salt spreaders. Unlike standard SES kits, this Severe Service version features single-convoluted Aeon hollow rubber springs that resist weight more aggressively, reducing sag, sway, and body roll under demanding loads. The patented Aeon rubber spring technology delivers a progressive spring rate that automatically adjusts to varying loads and road conditions. Heavy-duty powder-coated steel brackets ensure durability and corrosion resistance. Installation is simple and requires no drilling, airlines, or post-installation maintenance. After installation, maintain a 1/2" to 1-1/2" gap between the rubber spring and axle to ensure comfortable unloaded ride quality. Rated at 8,000 lbs capacity and backed by Timbren's Lifetime Limited Warranty and 100-Day Money Back Guarantee.
