Heavy loads can cause a trailer to sag and sway, making it harder to control. This suspension enhancement system uses hollow rubber springs rated for 15,000 lbs to help keep the trailer level under weight. As the springs compress, they stiffen to add support and stability, reducing body roll and improving tracking behind the tow vehicle. The result is a steadier, safer towing experience even when hauling serious weight.
Bumps and potholes can rattle both the trailer and what’s inside it. The Timbren setup acts like a built-in shock absorber, with hollow rubber springs that collapse progressively to soak up road shock. Light loads ride comfortably thanks to one inch of clearance that lets the original leaf springs move freely. As more weight is added, the springs engage and cushion the impact, helping keep the ride smooth and the trailer steady.
Off-center cargo or sharp cornering doesn’t have to throw the trailer off balance. Each rubber spring works independently to support its side, helping to control body roll when swerving or turning. The system automatically adjusts to uneven loads, so both sides stay planted and stable when the road or cargo isn’t perfectly even.
Over time, constant hauling can strain the trailer’s suspension and hitch. Mounted under a steel frame, this system sits above the axle to raise ride height slightly and share the load with the existing leaf springs. It installs directly onto the frame with included brackets and hardware, extending suspension life and helping everything underneath stay clear of scrapes and strain.
Each spring stands 4-3/4" tall and 5-9/16" in diameter with no load, compressing to about 2-1/4" tall by 7-5/8" wide when loaded. Designed for single-axle setups or tandem applications using two kits, it’s made to install on trailers with under-body steel frames. Once in place, it works automatically—no air lines or adjustments—just lasting support you can count on for every mile.
