Timbren Trailer SumoSprings utilize the same micro-cellular air springs as SumoSprings. The springs mount above trailer leaf spring assemblies and create a cushion between the axle and trailer frame. Trailer SumoSprings reduce wear and tear on body-frames, windows, doors, closets, mounted TV’s, and other components by minimizing bounce, hop, and sway associated with most tow-able RV’s.
Trailer SumoSprings reduced sway and bounce in the trailer results in increased driver control, ride comfort, reduced maintenance costs, and reduced overall cost of trailer ownership. Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles, proof of the craftsmanship that goes into every piece. They install with standard hardware and provide consistent support without air lines, compressors, or routine adjustments.
