Features to know about
Stop the Rear-End Sag: 6,000-lb Progressive Rubber Support
Heavy loads and trailers can make the rear of your vehicle dip and your headlights point skyward. The Timbren Rear Suspension Enhancement System uses 6,000-lb-capacity Aeon hollow rubber springs that mount above the rear axle to hold things level. As weight increases, the springs get stiffer, keeping the truck from squatting and improving steering, braking, and overall control when hauling or towing.
Smooth Out the Rough Stuff: Hollow Rubber That Absorbs Shock
Rough pavement, potholes, and uneven terrain can make a loaded ride feel harsh. These hollow rubber springs act as built-in shock absorbers that cushion bumps before they reach the cab. The extra elasticity of the rubber provides more travel than microcellular urethane alternatives, so you get a smoother, more stable ride when carrying heavy gear or pulling a trailer.
Stay Balanced and in Control: Independent Spring Action
When your load isn’t perfectly centered or a gust of wind hits, each Timbren spring reacts on its own to keep you steady. The independent left-and-right action evens out off-center loads and cuts down body roll when turning or swerving. That keeps both tires planted so you feel less sway from side to side on highways or curvy roads.
Bolt On and Go: Simple No-Drill Installation
There’s no air lines, compressors, or gauges to mess with here. The vehicle-specific brackets replace your factory bump stops using included hardware—no drilling required. Once bolted in place, the system automatically engages when weight is added and stays out of the way when unloaded, giving you reliable support without any upkeep.
