3,000-lb Capacity. These hollow rubber springs sit above the rear axle to help stabilize and level your Toyota Tacoma. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.
Whether you're hauling heavy loads in your bed or cargo area or towing a trailer, you will often see the rear of your Toyota Tacoma sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but also more of the vehicle's weight. Because less weight is on the front axle, the front tires are making less contact with the road. Overall 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.
The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the leaf spring sits, 1" 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 that 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 increases resistance, stiffening the suspension and keeping your Toyota Tacoma level.
Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your 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 you are hauling off-center loads.
Because your vehicle handles better with the springs, less turbulence will be passed along to the trailer and this helps 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 a passing semi) because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.
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'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. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Today we will be reviewing part number TTORTUN4L. This is the Timbrand Rear Suspension Enhancement System. It is designed to improve suspension, handling and safety. These are going to be vehicle specific, so to make sure they are going to fit your particular year, make and model, you can refer to the vehicle list at the bottom of the product's product page. It's going to provide additional support as needed so you always have a nice, smooth, comfortable ride. It's actually going to allow the lead springs plenty of movement while cushioning light loads. It will not affect the empty ride of the vehicle.
It is designed to become more rigid as more weight is added, which is going to increase stability. It's also going to reduce vehicle sag. Overall it's going to provide better performance while hauling heavy loads. They are designed to work independently, side to side, so it's going to help compensate for off-center loads. It's also going to help produce body roll when swerving and turning corners.
They actually act as shock absorbers, taking the force of bumps and rough roads, which is also going to help extend the life of your vehicle's suspension system. It's going to include the 2 hollow rubber springs, the vehicle specific brackets, and all the hardware that's necessary for a simple installation. They are designed to replace the axle bump stops on your frame. For the installation, no drilling is required. They are going to offer a capacity of 3,000 pounds, but you want to be careful not to exceed the vehicles' weight carrying capacity. They are designed to work with a suspension system that's in good working order. So the way that they install is that you will have to loosen the axle U-bolt and remove the existing bump stop. Then you are going to mount this portion to the axle and the U-bolts are going to go over the flat portion here, right at the base of those wings.
That's going to help distribute and also keep the U-bolts in place. Once you have that on there, you are going to tighten the U-bolts back down. Now the hardware on this system is designed to be installed from the bottom, going up. So the head of the bolt has an Allen tool designed to it, so you will need to use an Allen key or an Allen tool to get it tightened down properly. There is going to be a washer located on the inside of the spring here. So you can see that there, peaking in there.
The washer is already installed, so you want to make sure that the washer is lined up with the mounting hole. It's going to set on that portion there. Again, the hardware is going to come up through the slots, making sure that it goes through the washer. Then you are going to install the lock nut through the larger hole here, making sure it goes down all the way on top of that bolt. So you may need to use an extension for your socket wrench to reach all the way down there and get that seated correctly. Now the actual bump stop, or the spring, is going to give us an overall length of about 3-5/8". That's going to do it for our review of part number TTORTUN4L. This is the Timbrand Rear Suspension Enhancement System. .

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

These spring stops seem like a heavy duty quality product. Very easy installation on my 13 Nissan Frontier by jacking up vehicle under shock mounts and removing tire, then clean area with compressed air and remove clamp nuts with air gun (if owned) remove old stops and install new stops and retighten nuts. I have about 1/2" to 3/4" clearance as advertised. Have not been able to haul anything yet but am sure they will help greatly. Also do one tire at a time (Safety) sorry no pictures. etrailer was quick to process and ship order. Great Business. Thanks etrailer Dennis O. 170343

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
I can't speak to ease of installation, I have a buddy with a car shop and it's just as easy to let him do it. As for ride with and without a load, this does what it says it will. Squat on my 2013 Nissan Frontier was greatly reduced when towing. There is a definite 'gallup' when you hit a small pot hole or bump in the road when under load, but it quickly fades away. I recommend these if you need occasional support but don't want to sacrifice unloaded ride. 145946

Everyone told me to use super springs to help handle the extra weight from my truck camper,so I bought them- What a WASTE of my money! A neighbor told me about your product, so I purchased a set - They are great! They work perfectly! My Nissan Frontier handled great. I love these things! Easy to install and they don't affect my ride or handling. 155075

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

Bought this product for a 2012 Nissan Frontier. The installation and product is a little different than for most vehicles but the online information was good enough for me to pick the right product. Delivery was quick and installation was easy. Haven't load tested the product, yet. 261181
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
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
2009 Tacoma, rear supports, easy install, jack it up, take off wheeel, remove 1 u bolt holding leaf spring and loosen the other, remove old bumper and slide in a new one, tighten & you're done. 35471

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
