An example of sag on a vehicle's rear axle under a heavy load

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.


Diagram of the Timbren spring installed

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.


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 are hauling off-center loads.


An example of a trailers swaying

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.


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 when loaded. 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. And more elasticity allows for a more comfortable ride when loaded or towing because the rubber has more travel.

  • Timbren TFRF53A Install Issue On Ford F53 With Limited Driver Side Clearance
    Hey Don, thanks for reaching out. Yeah, the driver’s side on those F53 chassis can get tight, you’ve usually got brake lines, wiring, or a bracket sitting right where you want that Timbren to live. You’re doing the right thing paying attention to it, because you don’t want that spring contacting anything once it starts working. What matters is that the Timbren can compress straight up and down without hitting or rubbing anything through its full travel. If it’s sitting right next to a...

  • Front and Rear Suspension Enhancement for 2017 Jayco Precept 31UL
    The front set of SumoSprings you'd want for your 2017 Jayco 31UL Precept is the part # SSF-170-40-2 and then for the rear you'd need to go with a Timbren part # TFRF53A or the SumoSprings # SSR-187-54-1.

  • How to Reduce Jolting Feeling in Steering and Rough Ride on a 1998 Fleetwood Pace Arrow Motorhome
    In order to reduce the jolting feeling in your steering you are going to want to add a steering stabilizer like the Roadmaster Reflex Steering Stabilizer part # RM-RSSA. The Reflex Steering Stabilizer contains a tempered steel spring that will work to return the steering wheel back to its normal state while turning therefore reducing the jolting feeling. The only issue that you are going to have is that they do not make a bracket kit specifically for the V10 model, just the V8 model. However,...

  • Choosing Between SumoSprings or Timbren for 2013 Fleetwood Storm 32BH
    Although either the # SSR-187-40-1 Sumo Spring or the Timbren # TFRF53A would be a great choice, the Timbren Aeon spring is actually rated higher at 8600 lbs, versus 2600 lbs for the Sumo Springs alternative. Neither of these options will come into play unless the factory suspension gets compressed. If ride quality is the more important consideration, the Sumo Springs option is what I'd recommend as they' give a more supple ride. If reducing roll in the corners is foremost in your mind,...

  • Front or Rear Timbrens to Start With on 2006 Motorhome With Ford F-53 Chassis
    That's a good question, and for your 2006 motorhome on a Ford F-53 chassis, the best option to start with is using the Timbrens on the rear of your motorhome: - Timbren Rear Suspension Enhancement System # TFRF53A The reason for that is a motorhome has more bounce/movement at the rear due to the axle placement compared to the front. There is a significant portion of the motorhome that is behind the rear axle compared to the front, and that causes the back end to be less stable overall....

  • Comparing Timbren and SumoSprings Suspension Enhancement for 2019 Thor ACE 30.2 Motorhome
    The biggest difference between the two for your 2019 Thor ACE 30.2 motorhome, and the reason why I highly recommend the SumoSprings over the Timbren, is what each product is constructed from. The Timbrens are made from a strong, rigid rubber while the SumoSprings are made from microcellular urethane. This is important because it means the SumoSprings will compress more gently, while the Timbrens are known to give a much stiffer ride. The front axle and rear axle fits for your 2019 Thor...

  • Recommended Suspension Improvement for a Jeep Wrangler When Towing a Trailer
    Both the Timbren # TJRJK and the SumoSprings # CSS-1195R will help with sag and stability while towing. However, they will affect the ride when no towing as well. The Firestone Coil-Rite Air Helper Springs # F4173 are adjustable from 35 psi all the way down to 5 psi. This will give them up to 1,000 pounds of load-leveling capacity when filled, and then feel basically nonexistent when deflated.

I feel their jounce springs are great for commercial applications and extreme weights but with the delicate trims and construction of your cabinetry the SumoSprings Front # SSF-170-40-2 and Rear # SSR-184-40-1 are going to be a much better option.

    I reached out to my contact at Timbren and this is something that is not all that uncommon. If the brake lines on the axle of your 2013 F53 Chassis are underneath the Timbren Rear Suspension Enhancement # TFRF53A you can carefully bend them out of the way so they will not be underneath the spring when it contacts the axle. There is not a replacement clip set that will secure the lines in the new location so if the lines are pretty stiff and out of the way using no clips is fine, or you...

You have a Ford F-53 chassis with a GVWR of 20,500lbs. I find the SumoSprings work better as they are not as stiff as the Timbren Front # TFFF53MH and Rear # TFRF53A suspension.

Both work independently to help compensate for off-center loads and reduce body roll when swerving and turning corners. They also help to add support reducing sag and minimizing sway. Both have progressive load control so they become stiffer the more they are compressed to help with heavier loads. For your 2021 Ace 32.3 Motorhome I would recommend the SumoSprings...

Timbren is a little more well-known but we have received feedback from our customers that the SumoSprings offer better ride quality as they aren't as stiff. If you are comparing the rear Timbren # TFRF53A with the rear SuperSprings # SSA41 for the leaf springs then they are comparable when it comes to performance but they work slightly different.
