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 RV trailer suspensions with a spring over axle suspension setup with a tie-plate width of less than 3.25 inches. A custom kit is required for tie plates over 3-3/4 inches up to 6 inches.

Timbren SES kits require zero post-installation maintenance and can be installed in under 30 minutes, right from your driveway.
