Towing top-heavy loads, like your RV trailer, can impact your ability to keep the trailer moving on a straight path down the highway. This doesn’t just make for a challenging drive — it’s dangerous.

Designed exclusively for RV trailers, Timbren SES kits for trailers keep your load level at all times. This 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 that has a 2 ⅜-inch to 3-inch diameter axle with 2-inch wide leaf springs. 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.

Your questions, answered

You want all the info before choosing the right towing solution for you. And we want to help.

An underslung axle refers to the way the leaf spring sits below the axle instead of above the axle. This gives it a lower center of gravity, allowing for more stability.

Timbren SES for trailers supports the existing trailer factory suspension system in order to reduce sag, sway, and roll while improving ride quality.

Silent-Ride and Axle-Less trailer suspensions, on the other hand, completely replace the factory suspension.
