Reduced axle sag with Timbren suspension enhancement

Just like the rear of your vehicle will sag under the weight of a fully loaded bed, the front of your vehicle will sag when under the burden of heavy equipment such as a snowplow. In this case, the front axle is handling not only the weight of the equipment, but also more of the vehicle's weight. Overall vehicle handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.


Install diagrams of Timbren hollow rubber springs

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your front axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down so that the bottom of each spring touches the axle. Because each spring is making constant contact with the axle, it is always working to cushion and support your factory suspension.


Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when you're carrying off-center loads.

A snowplow mounted to the front of the truck will require extra suspension support for the front axle.

Timbren's Suspension Enhancement System will help raise the front end of your vehicle when you're using heavy equipment like a snowplow. This ensures that your headlight beams will be pointed in the right direction and tire wear will be reduced. If the plow is off-center or has an extension, the springs will automatically compensate for this as well.

An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

When I installed these on my 2015 Nissan frontier sv, the bump stops did not sit square with the top plate, but at an angle I wasn't sure how this would effect travel of the timbrens or the function. Not sure if others have same issue or not. Long story short, this positioning caused excessive stress on the mountingnut location and tore at the bottom right next to the mounting bolt. Timbren was contacted and a replacement was sent free of charge. Excellent customer service- friendly, great attitude to help me out. Performance - handles larger bumps/dips better but smaller ones are felt more. Stiffens up front, notice wind gust influence substantially less. Do feel performance has diminished after a year. Upgrading shocks/coils for lift and better ride. May remove timbrens altogether. Someone with a plow would appreciate these more.

Here is my install on my 2WD Ford Explorer front. Easy job, I don't recommend installing these with lowers suspension as the ride is too harsh, I adjust mine back to stock. Works the way I need them to.



by:

These are great, but would not line up correctly on the front of my nissan frontier to get an even load. I sent pics to etrailer and talked to a "suspension specialist" and was told that it was normal to have the timbren to be mashed down on one corner rather that and even depression. I called/sent the same pics to timbren and they sent me some tapered shims and longer bolts free of charge, so they would line up to get an even load on the timbrens. They also said that they should have been sent with the shims and longer bolts because this alignment problem was not unusual. Great product, but less than impressed with the decision made by etrailer.



by:

Complete game changer in the way my suspension rides with the plow on the front of the truck. The "V" nose plow used to scrape the ground every time there was a pothole or dip in the road. Now that problem no longer exists.



by:

Great product would recommend and buy again. Instalation was a snap did it in about 2 hours front and rear.

Easy install took about 20 minutes on my 2017 Ram 3500 SRW. Had about 1/2 inch clearance as recommended. Loaded up my 5th wheel (2350 hitch weight) and about 200 lbs of gear in the bed. Just got back from a 800 mile camping trip through mountains of TN. You can really feel the difference around those sharp corners and uneven surfaces. The truck felt firm and controlled not hard and jarring as some have mentioned. Going over those overpasses with the wonderfully smooth (Not) joists was greatly improved. The truck would squat and rebound again, with a firm controlled response. Driving without a load felt the same as before without them. I would highly recommend these! Ordering from etrailer continues to be my go to option!



by:

The product came very fast. I already installed it the same day on my 2009 Dodge Ram pickup. It looks like it should do a fantastic job. I'll know better when I hitch up my travel trailer.



by:

Took about 45 minutes to install. But that was 2 trips into the house cause my deep drive sockets were buried. F-350 gasser with 8’ box, Fiberglas cap, 200lb wooden storage drawers and estimated 400lbs in tools. I tow a 14k bumper pull dump that squats the truck. I installed the spacer with the timbrens and it sits on the original axle stop. Ride quality is unknown as I haven’t driven it yet.

I bought the timbren SES 121474110. I am not really satisfied with how these helped my trucks towing stance. The truck tows the same. I carry an in bed tank with 50 gallons of fuel in addition to the 35 gallon fuel tank from factory. The truck rides the timbrens the whole time. Thats okay, my problem is that the truck squats the same amount with these when I hook up my car trailer. The truck still goes straight down to the load leaves (pretty heavily squatted) the same as before. Did I get a light duty version? dont feel these meet the 6,000 Ibs capaticy as advertized. I think I should have gotten air bags. The product was well made. so they still get 2 stars. Just not what I thought it should have been.



by:

I know it will be lovely when loaded or the trailer on. However,it rides like a wagon empty with brand new premium shocks and struts empty. Thud thud thud. You really cannot feel the shocks or suspension. Found exact same item plentiful for 60 bucks on eBay after I bought these for 250. I may cut these in half or put air bag on. I do not like the ride empty. No hard feelings. It is a good product maybe just not for me.



by:

Installation was a breeze, removed old bump stops installed Timbrens in about 30 minutes. Haven’t put a load on them yet so I’ll update later. Installed on a 2008 Silverado 2500HD..



by:

Was able to install these with a 15mm flex head ratchet wrench and lifted the rear of the truck to make it easier. 30 minutes to take off 4 nuts and put em back on. 2 minutes assembling the timbrens with the added spacer. I have a f350 with a salter and plow. Loaded with salt the lights shoot up and in the snow ?? it’s like hitting hyper drive and you’re blinded. These helped big time. Very happy so far.



by:

Out of the box fit !!
Only issue I had
was keeping the wedge from moving during installation



by:

The pro: The longer, heavier bump stops worked great when hauling my mustang home from Chicago. The truck stayed level and handled great.
The con: I had to remove the bump stops for everyday use. They limited my suspension travel causing a stiffer ride.



by:

I am so glad I bought these for my truck. I was able to install them myself using a jack and jackstands. The ride is bit rougher now; but the suspension is totally awesome compared to before. I am able to haul a bit more weight when needed.



by:

very good product ,received just in time and fit perfectly on my GMC savana 2000 .Be sure to clean the two receptacle thats help.
très bon produit , reçu dans les délais et s'ajuste parfaitement . Assurez-vous de nettoyer le receptacle cela facilite l'installation.

After successfully using air shocks with on board compressor on our 2001 F250 for years, I almost automatically put the same setup on our new 2022 F250. We tow an 11k lbs travel trailer. Then I read reviews on Timbren Suspension Solution & thought, worse case I’ll end up with both solutions. After spending 20 minutes installing Timbren and towing the trailer a few miles, it became obvious I didn’t need air shocks, or anything else. The truck & trailer drive as one. Our rig is level and rides great. When the trailer is unhitched, the Timbren’s aren’t engaged - just a normal F250 ride.

The Timbren rear suspension bump stops are the best by far. I installed this unit on a 3rd gen Toyota Tacoma which became an essential item for safety towing purposes.

The main reason for purchasing this product was for aided support for towing. This is essential for those who tow boats, tear drop trailers or medium sized campers.

The stock bump stops are relatively small in size which is standard for other vehicle manufacturers however Timbren's bump stop are made with such high quality material and craftsmanship.

This also helps in preventing in stressing the front suspension from becoming raised which can affect your steering when your towing. The Timbren bump stops also helps in preventing your rear suspension from the "sagging effect" which can cause stress to your tires.

I recommend that when you install the bumps stops, check the lugs every quarter or depending on frequent you tow, to include tightening the lugs with a torque wrench to ensure it's torue specification(s).

This product has given me peace of mind when traveling long distances and when camping off the grid. Timbren also has good customer support service however etrailer has paramount customer service as well.

I’d seen similar products rated in the 4,000 lb ratings but I went with these. I’m not a mechanic but I removed the factory bump stops and installed both these in 30 minutes or less. I used my rolling jack and lifted from the drop hitch and easily removed the old ones and soapy water and 1/4 twist and these were on. Placed a block of wood in the space between these coils and lowered the jacks then pressed it with my tractor to confirm full engagement. I carry a lot of tools on a 2020 Chevy 2500 I do feel a bit of butt bounce on large bumps but other than that I’m very pleased.
