SES kits are designed to keep the vehicle level at all times and prevent roll and sway. The Aeon® rubber springs found in a Timbren SES kit have a progressive spring rate. In other words, you are guaranteed a soft, comfortable ride at all times.
Better Ride Quality
Whether we’re towing with our Nissan Titan or our Toyota Tundra our Timbren SES kit has been a game changer. Reduced all sag in the rear plus helps the tow rigs gain maximum control. Over a year with SES and we would never go back.
