Specs:
Whether you're hauling heavy loads in your bed or cargo area or you're towing a trailer, you will often see the rear of your vehicle 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 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, 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 vehicle level.
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 are hauling off-center loads.
Because the 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.

This thing is robust. Solid and looks indestructible. Replaced my OEM shocks to Bilstein and together they seem to work well. Installation was easy.
My Tundra does not squat now with heavy loads and the ride is firm not hard.
Thanks for selling a great product.
installation was extremely easy (after tangling with that one stubborn u-bolt nut found with any job). Instructions are straight forward and complete. Last time we loaded our ft. 18 camper on my Tacoma (tow capacity 7000 Lbs) I thought I was in the space shuttle at liftoff! Attached camper after installation and had rear end sag,even with bed filled with wood and coolers. Would love to post review after trip to Erie this weekend.
These items are built well but don’t mistake them for a cure to overloaded springs. I installed them prior to installing my camper and the truck was overloaded and riding with these against the frame. Rough ride for sure! So while they are built well, they really don’t help in my situation.
Do exactly as advertised; have no idea why anyone would get air suspension when these do the trick with no hassle and automatically adjust themselves based on the load. Not to mention they are maintenance free.
Easy to install and really stabilizes that soft Tundra leaf pack.
The customer service was outstanding throughout the process.
Installed before going to trade my small travel trailer in on a bigger/ heavier one, didn’t do to well with the smaller/lighter camper, made the drive very bouncy!! But the ride home with the heavier camper was great, kept the truck level and helped it handle better on the road
A friend recommended these, have always run air bags in the past. Price point was rite and install is a breeze, hopefully they work well.
Easy install, so far so good. Pulled camper on with my Tacoma.
Have not got them installed yet, but the shipping was excellent & I expect this product to do what it is supposed to.
Excellent product
Worked great while I had the truck. I now no longer own the Truck.
Look like good quality. East to install.

After a yr of towing with them they have softened a bit. They do cause a little more sway when towing. Normal ride height truck they sit on your bed frame so you will feel evry bump
