When you’re hauling a heavy load or towing a trailer, rear-end sag can throw off your steering and braking. The Timbren Rear Suspension Enhancement System adds up to 6,000 lbs of support with its Aeon hollow rubber springs that sit above the rear axle. As weight increases, the spring’s progressive design stiffens to keep your ride level and controlled. That means steadier handling, better braking response, and a safer, more balanced feel on the road.
Heavy loads can make every bump hit harder, but these rubber springs act like shock absorbers to take the brunt of rough terrain. They absorb most of the road shock so your truck feels smoother and more stable when loaded. The added cushioning also helps extend the life of your suspension by preventing bottoming out when things get bumpy.
Each spring works independently from side to side, which helps when you’re cornering, swerving, or carrying an off-center load. This independent action cuts down on body roll and sway so the vehicle stays planted through turns or when a passing semi kicks up turbulence. You’ll feel the trailer follow in line with less rocking and quicker recovery from sway.
Unlike air springs that need hoses, compressors, or manual PSI adjustments, this system bolts into the factory bump stop location using vehicle-specific brackets and hardware—no drilling required. Once installed, it works automatically with your factory suspension to provide support only when needed. That makes it an easy, maintenance-free solution for everyday hauling or towing without extra equipment to manage.

After a year it was still the best improvement I have made to the trucks. The Timbren Vehicle Suspension is something I should have installed long from the beginning. The ride is a little more stiff when empty, but thats not why the system was purchased for. Saved me from buying a $500 air bag system. I would recommend this product to anyone who hauls heavy loads.

Im still driving my slightly modified Ford F250 HD Powerstroke - your Timbren suspension anti-sway bags have been a life saver on my tires! The truck rides level and smooth without sway, even in high winds with my cargo trailers. Handling under heavy loads is also vastly improved. Now if I could only swap the front suspension stops with more Timbren bags the damned factory bumpers are riveted in place!
