When you’re towing or hauling, sag in the rear end can throw off steering and braking. The Timbren Rear Suspension Enhancement System adds up to 6,000 lbs of extra support above the axle to keep your vehicle level and stable under load. Each hollow rubber spring stiffens progressively as weight increases, so the truck stays steady whether you’re hauling gear in the bed or pulling a trailer down the highway.
Bumpy roads and uneven pavement don’t have to beat up your suspension. These Aeon hollow rubber springs act like extra shock absorbers, taking the hit from potholes and rough surfaces before it reaches the frame. They cushion light loads while allowing normal leaf spring movement, keeping the ride comfortable when empty and steady when loaded.
When curves or crosswinds push your setup around, each Timbren spring works independently to support its side of the vehicle. That independent action helps cut down on sway and body roll when turning corners or hauling off-center loads. With better roll stability, your vehicle feels planted and trailers track straighter behind you.
No air lines, compressors, or gauges—just a straightforward install that replaces your factory bump stops. The custom brackets bolt directly to the frame above the axle with no drilling required. Once installed, there’s no air pressure to monitor or parts to adjust—just reliable support that works automatically every time you load up.

Works great. Still looks like new after a year and we use it hard.
Eliminated rear end sag when towing and also stabilized the rear improving drivability. Highly recommend.
smart way to protect your safety and vehicle
Yes, buy it!!!!!
Easy to place on vehicle, haven't put tailer on yet, but clearance is 1/2 to 3/4 inch, should be perfect.
Kit does a great job making up for the underbuilt suspension on my excursion. Installation was straight forward although a bit awkward from under the truck in the driveway. The price is way high for some rubber and bolts, but that's apparently from the manufacturer as opposed to etrailer. Good product, just a shame to pay so much to make up for ford's known shortcoming.
The Timbren rear suspension enhancement system works great. It leveled my 2000 Ford Excursion Limited with my 31ft. 6000lb camper before using the weight distribution hitch. Before my excursion sagged in the rear. The crew at etrailer were Awesome! Great customer service and they upgraded my shipping for me for free. Only took me 30 minutes to install. Thanks etrailer!
Installed on 2000 Ford Excursion to keep rearend from sagging when towing 24' Thompson 240 Fisherman Hardtop Boat. Worked like a charm once I got the stock bumpers off. Had to get the [$] [discount store] 4" Grinder out to remove stock bumpers. Works great, so far - just like described. Bumpers remain hanging in air with no contact until a heavy load is applied inside Excursion or on trailer hitch. Excursion remains essentially level with Thompson Boat/Trailer hitched-up.
Might ba a 5 star after I test it with a loaded trailer. Easy install on my excursion.
To be honest, I decided not to install them. I still have it in a box because of I’d have to let the air out every time I put it on the rack change a tire change the oil do any kind of maintenance and then pump it back up again I didn’t know that with my old set and that’s what fell apart, so I still got them in the box. Haven’t used them at all.
Product installed very easily, spacing seems a bit much from the bottom of the product to the axle, but that could just be me. Nothing against you guys, but the package was delivered VERY damaged, some of the contents were showing outside the box.

There should be a sizeable gap between the Timbren springs and the vehicle axle. The Timbren kit should only engage the axle when the vehicle is bearing a hefty load. This is to prevent un-loaded ride quality from being altered, but provide extra support when a heavy load is in the mix.
This was a great solution for me! I have a bumper-pull RV trailer that is 10k pounds and 1k tongue weight. My old Excursion squatted that weight terribly even with a weight distro hitch. The factory bump stops were totally gone years age. These bump stops almost totally removes the squat I got from the RV trailer. Thinking about doing the front ones as well.
Game changer! 03 4x4 Excursion. When installing, I had to jack up the chasis to get the Timbrens in there. That makes me think my leaf springs have seen better days but idk. After installing, we took our 20’ equipment trailer and two snowmobiles to the Upper Peninsula. These Timbrens made a huge difference in the way the truck handles. I used to slow down for the sweeping turns going through cities on 127 but now the truck tracks confidently and that is no longer necessary while towing. These are always engaged when not towing due to the Excursions soft rear springs. My only regret is not getting them a while back when we towed our 30’ camper with a weight dist. hitch. That would have been a great combo.
This did a great job. It significantly reduced sway when I pull my trailer and improved the ride significantly.

Excursion factory springs seem underrated. Timbren’s recommended spacing still allows to much rear end squat. I added more spacers for No gap. Actually helped with body roll when unloaded. This spacing was discussed with Timbren representative beforehand. Timbren has lifetime warranty
