- Progressive Aeon Rubber Springs – Advanced hollow rubber springs automatically increase support as load weight increases

- Fast DIY Installation – Simple bolt-on installation can typically be completed in under 30 minutes using basic hand tools
Features & Benefits
The Timbren SES Suspension Enhancement System is engineered to improve your truck’s handling and stability whenever additional weight is added to the rear suspension. Heavy towing and hauling can cause rear-end squat, unstable cornering, excessive body roll, and poor steering response—all of which negatively impact ride quality and driver confidence. The Timbren SES system helps solve these issues by providing additional suspension support exactly when it’s needed most.
At the core of the system are Timbren’s patented Aeon® hollow rubber springs. Unlike traditional helper springs or air bag systems, Aeon® springs deliver a progressive spring rate. This means the springs respond softly during normal unloaded driving, but automatically become firmer as additional load pressure is applied. As cargo or trailer tongue weight increases, the springs push back harder to help level the truck and stabilize the suspension.
This progressive design allows the system to maintain a comfortable unloaded ride while dramatically improving stability under load. After installation, the Aeon® springs are designed to sit approximately ½-inch to 1½-inches away from the vehicle frame during normal unloaded driving. This built-in clearance helps preserve factory ride comfort while allowing the system to engage only when additional suspension support is needed.
Unlike air bag suspension systems that require compressors, airlines, pressure monitoring, and ongoing maintenance, the Timbren SES kit is completely maintenance-free after installation. There are no leaks to worry about, no adjustments required, and no complicated setup procedures. Once installed, the system works automatically every time you tow or haul.
Designed specifically for the 2022–2026 Nissan Frontier, this rear suspension enhancement kit is ideal for towing campers, utility trailers, boats, and work equipment while also improving control during daily hauling and off-road use.
