Features & Benefits
Heavy towing and hauling can place extreme stress on your truck’s rear suspension, causing rear-end squat, unstable cornering, excessive sway, poor ride quality, and difficult handling. The Timbren SES Suspension Enhancement System is engineered to provide additional rear suspension support exactly when your truck needs it most.
At the heart of the system are Timbren’s patented Aeon hollow rubber springs. Unlike traditional overload springs or air bag systems, Aeon springs use a progressive spring rate that automatically adapts to changing load conditions. As additional weight is applied to the rear suspension, the rubber springs progressively stiffen and push back harder to reduce squat, sway, body roll, and suspension compression.
One of the biggest advantages of the Timbren SES system is its ability to preserve unloaded ride quality. After installation, the Aeon springs maintain approximately a ½-inch to 1½-inch gap from the vehicle frame during normal unloaded driving. This allows your truck to retain factory ride comfort until additional load support is needed.
Unlike air suspension systems that require compressors, airlines, pressure monitoring, and routine maintenance, the Timbren SES kit is completely maintenance-free once installed. There are no leaks to worry about, no pressure adjustments required, and no complicated setup procedures. Once installed, the system automatically engages whenever load support is needed.
The Aeon springs also function as secondary shock absorbers, helping smooth out rough roads and improve overall ride control whether loaded or unloaded. This makes the system ideal for towing RVs, hauling trailers, carrying tools and equipment, or transporting heavy loads on a daily basis.
