Designed exclusively for RV trailers with a spring under axle suspension setup. This Timbren SES kit creates a safe, controlled ride so smooth, you might forget you’re towing your RV trailer altogether.

How? Our Aeon® springs deliver a progressive spring rate. As load increases, our springs push back harder, eliminating your RV trailer’s squat, sway, and roll while providing a safe, smooth ride. The natural rubber properties of our Aeon® springs also cushion road shock, reducing hard hits on your trailer from driving over bumps and dips.

This SES suspension upgrade fits your RV trailer suspension with an underslung axle setup and a leaf pack width less than 2.25 inches. Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit.

What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, our kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.
