When you hitch up a trailer or load down the bed, the rear end can sag and throw off your braking and steering. The Timbren Suspension Enhancement System adds 6,000 lbs of load-leveling capacity to keep your vehicle level and stable when hauling or towing. The hollow rubber springs mount above the axle and stiffen progressively as weight increases, helping maintain balance and control without affecting light-load ride comfort.
Uneven pavement or washboard roads don’t have to punish your suspension. Timbren’s Aeon hollow rubber springs act like built-in shock absorbers, taking the brunt of bumps and jolts so the ride stays smoother when loaded. By cushioning road impact, they help extend the life of your factory suspension and prevent bottoming out on rough terrain or steep approaches.
When a curve or crosswind hits, each Timbren spring reacts on its own to support that side of the vehicle. This independent action helps reduce body roll and sway, keeping your ride stable through corners or when a passing semi pushes air pressure against your trailer. With less movement transferred from the trailer back to the tow vehicle, you stay more comfortable and in control.
Installing additional support doesn’t have to mean running hoses or setting air pressure. The Timbren kit includes custom-fit brackets and hardware that bolt directly onto the frame—no drilling required. Once installed, there’s no maintenance or adjustment needed. The springs automatically provide extra support only when it’s required, so you can go from driving empty to fully loaded without changing a thing.

Have you come back from that trip at this point? Where did you go? How did the Timbrens work out?

The Timbrens are working out very well and I swear by them to anyone who asks.

Over a year, and several heavy loads later, these Timbrens are still going strong. Easily the best addition to the truck and at the lowest cost.

Honestly the ride quality can be rough with the Timbren kits when unloaded. Some are ok with it or do not feel it, some like yourself can feel the difference. You can remove the spacer you just want to make sure that there is still a 0.5 to 1.50 gap between the rubber spring and the contact point when empty. If you are towing all the time then I recommend taking a look at an air bag option, however it is more money and a more extensive set up.

Best thing for the money. Would buy them again. The only thing I would try next time is getting a bigger spacer from the factory so there is little to no gap between the frame and the rubber spring. I only had a little over a half an inc but by the time I put my camper on the truck look like it is starting to square.
