An example of sag on a truck's rear axle under a heavy load. The Timbren Suspension Enhancement System levels the Toyota Tacoma.

When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the Toyota Tacoma sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the Toyota Tacoma's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall Toyota Tacoma handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the Toyota Tacoma's factory suspension to keep the Toyota Tacoma level and improve your driving performance.


Diagram of the Timbren spring installed

The Timbren system has a Toyota Tacoma-specific bracket that will be bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits one inch above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride you are used to.

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 provides increased resistance, stiffening the suspension and keeping the Toyota Tacoma level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the Toyota Tacoma. 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 hauling off-center loads.


An example of a trailers swaying

Because the Toyota Tacoma handles better with the springs, less turbulence will be passed along to the trailer helping to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or passing of a semi) because the movement from the trailer is not transferred to the Toyota Tacoma. This also works to make the sway subside quicker.


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 as the rubber springs work to prevent bottoming out on rough roads.

Compared to the competition:

Timbren's suspension enhancement systems are much easier to install than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

2010 Nissan Frontier with Timbren suspension components. Trailer is a Jayco X17Z with close to 450lbs of tongue weight. Pictures are a before and after view of the rear suspension droop. 52393


Comments

Since the Timbren install we have towed the camper on back roads with stop and go traffic as well as on the highway at 65 mph. The Pro4X does ride level and handles the added weight well. I wish I had a longer wheel base and a tandem axle trailer as on occasion we develop a slight up and down oscillation until the suspension settles down. It is noticeable when driving over long bridges. This is mainly due to the truck setup and not the Timbrens. We had this problem before the install and the Timbrens are making a difference.I have also hauled an estimated 780 lbs of hardwood flooring in the bed at 65mph and the truck handled it with no problem. It remained level and stable.

You might be able to adjust the tongue weight of the trailer and get that oscillation to settle. You want your tongue weight to be about 10-15% of the trailer total weight. Also if the trailer does not ride level, looking into getting a different drop length ball mount that will get the trailer level or even slightly nose down.

I purchased this kit to keep my 2013 Toyota Tacoma Double Cab Short Bed from bottoming out when it has a load in the bed. It really did the trick as well as improved the stability with or without a load. The only down side is that the suspension is much more stiff without a load in the bed. It took some getting used to, but after having them on for a couple months, it doesn't bother me. 106946

The order and shipping process was flawless -- the Timbrens arrived exactly when E-trailer said they would. An hour after they got here, I had them completely installed. As of this date (7/30/13), the posted instructions (and the ones that came with the Timbrens) are not quite correct for a new Tacoma, as I verified with a Timbren tech. (These are Tacoma-specific issues -- they may not apply to other trucks.) Do not jack the truck up. I ran the back tires up onto blocks (to give myself more room underneath) and set the parking brake. I put a jack stand under the differential -- probably not needed. I crawled under and did one side at a time -- loosen the u-bolts, remove the old bump stop, stick in the new Timbren, and tighten. Not technically demanding at all. My crawler dolly was very helpful. Some tips: use a 9/16 socket with an extension to put the nut onto the bolt inside the Timbren rubber spring and then tighten the bolt with an Allen wrench. When loosening the Tacoma's u-bolts, use a 3/4 socket. Depending on the clearance between the leaf springs and the frame, you may need to remove one side of the u-bolt assembly to install the Timbren because the angle of the baseplate is greater than the angle of the OEM bump stop. I was told that the u-bolt nuts on a Tacoma should be re-tightened with a torque wrench to about 70 foot/pounds. I found it a little tiring to lay on my back and torque the nuts, but then again I am verging on elderly. A young person in decent shape should have no trouble. I don't know yet if the Timbrens will help my saggy rear end when I am towing a trailer, but others have said that this will be very helpful. This is my second major purchase from E-trailer -- I am impressed with their selection, service, and pricing. 92404

Fairly easy to install. Haven't had a chance to try it out with a load yet but looking forward to it. Better than adding a leaf and raising it up and nothing to maintain like an air system would have. etrailer customer service is top of the line. 69032

Found these very easy to install on my 2005 Tacoma. The back end was beginning to sag some from overloading so added a helper spring to give the Timbrens some clearance and these fit in as designed. With a loaded 16' equipment trailer, the truck rides level and smooth.64558

Product is excellent. From the time I took the parts out of the box until the time I lowered the truck of the jack it only took me 45 minutes to complete the installation. Easy to install with only a few basic tools. The truck no longer sways around corners. It may ride a little stiffer but barely noticible. Well worth the price.51870

Seems like a good product, haven't pulled trailer yet. But unloaded drives well. Tell people that they need a 5.5 mm allen wrench & impact wrench to make install smoother.79630

  • What Is the Installation Like for Timbren Springs on a Toyota Tacoma
  • The install for the Timbren Rubber Enhancement Springs, part # TTORTUN4L, is fairly easy, just one bolt and nut to install the spring and bracket. It bolts in the same location as the factory bump stop. You will just need to jack under the frame of the truck to relieve the tension on the suspension. Remove the bump stop, 1 bolt and nut, and finally install the Timbren spring again with 1 nut and bolt. Repeat on the other side. I have included a link to the directions. I have added links to a

  • Using a Weight Distribution System to Level a 2006 Toyota Tacoma and Cargo Trailer
  • The best way to reduce sag at the rear of a vehicle when towing a trailer is to use weight distribution. I recommend a system that has built-in dual cam sway control to prevent trailer sway before it starts. For the right sized system, you will need to know the tongue weight and gross trailer weight of the trailer when it is fully loaded and ready to tow. For example, if the tongue weight of the trailer is 400 pounds, you would need a system with a 200 to 600 pound tongue weight capacity. You
