Specs:
When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the vehicle 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 vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.
The Timbren system has a vehicle-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 vehicle level.
Each hollow rubber spring works independently to support the driver's or passenger's side of the 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 hauling off-center loads.
Because the vehicle 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 vehicle. This also works to make the sway subside quicker.
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.

Today on the 2001 Ford Ranger we are going to install part number TFRR0504A from Timbren. Before we started we actually did a few test runs. We did it fully loaded, halfway loaded, and empty. Now we will go ahead and install the Timbren kit and then we will go ahead and try it again.
The suspension enhancement actually replaces the factory bump stop right here. What is going to happen is we have got to take off this factory bump stop, it comes off there is usually a bolt on top, and there is a part that comes down here that gets clamped onto the axle and replaces the bump stop here on the bottom. Lets go ahead and take this off first.
We will go ahead and start the sub assembly. Whats going to happen is this screw will go on the inside. So just take it and put it into the end of the socket, and there is a little washer inside so you have to work it inside the washer. And it is going to bolt on to the top of this bracket here. And this bracket will actually get bolted onto the bottom of the truck. All right when you tighten these down you want to get these about hand tight. All right we will go ahead and install this part on the bottom of the frame now.
Go ahead and slide our lower bracket into place. Take care, stay away from any brake lines or any other components. Line it up straight. And then what happens is the clamp goes on the bottom and the two bolts will go through and hold it into place. When you tighten down the bolts you want to do them evenly on both sides. With one complete we will go ahead and move to the other side and start on that one.
On the one completed side you can see that we have about one inch of space between the rubber bushing and the bracket below it. When you get loaded up it is going to take up that space. The more load on it the harder it works. Here we go again, after the install we will show you how we can reduce the body roll in it with the heavy, light load, and no load. With a few simple steps and a couple simple hand tools we have our suspension enhancement installed. And there you have it for part number TFRR0504A from Timbren.

Excellent add on my Mazda B4000, 2002. After 9 years, my rear supension needed a lift-up and that was the perfect solution. Easy to install and cheap with significant improvement when taking corner, stop and acceleration. Everything hold on tight. At the beginning the Timbren was very stiff and hard, even too much when driving empty but now it did soft-up and I got use to it. The big difference is when the trunck is loaded... WOW. Very good purchase.7077
