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.

  • Availability of Air Lift Air Helper Springs for 2024 Ford Maverick Tremor
    Hi Brian; although there are Air Lift 1000 Air Helper Springs # AL42WQ for the 2024 Ford Maverick they are not a fit for the Tremor models. The only option for suspension enhancement on your Tremor is the Timbren SES # T25MR. These will give you the extra support you're looking for when hauling. They have a load-leveling capacity of 8,600 lbs, satisfaction guarantee, and come with a lifetime warranty.

  • Timbren Bump Stops For A 2025 Ford Maverick LARIAT Hybrid AWD
    Hi Andy! The Timbren bump stops # T85MR and # T25MR will indeed fit your 2025 Ford Maverick LARIAT Hybrid AWD. However, The # T25MR is rated up to 8,600 pounds, so it will likely be way to stiff and be very jarring when you hit them. The 4,800 pound # T85MR would be the better choice out of the two. With that being said, I think the best choice for your vehicle is the Air Lift 1000 Air Helper Springs for Coil Springs - Rear # AL42WQ. They are adjustable to match the load you are carrying...

  • 2022 Ford Maverick Timbren Fitment and Suspension Enhancement Alternative
    To install Timbrens on your FWD 2022 Ford Maverick you'll have to go with the Timbren Active Off-Road Bumpstops # T85MR as the Kit # T25MR you're looking at isn't designed to fit your truck. Timbren markets the Off-Road bumpstops as being more forgiving which isn't a bad thing considering Timbren kits tend to be a bit more harsh when it comes to unloaded performance. For something that gives you a bit more flexibility in performance I recommend using the Air Lift 1000 Air Helper Springs...

  • Selecting The Correct Timbren Jounce Springs For a 2022 Ford Maverick
    We have 2 sets of Timbren Jounce springs for your 2022 Ford Maverick. The 8,600LB Springs # T25MR and the 4,800LB Springs # T85MR. The 4,800lb springs are their off-road bump stops and will provide you more suspension travel than the standard 8,600lb springs. If you want to have the additional suspension travel or plan to off-road with your Maverick you will want the 4,800lb kit. If you only intend to use your Maverick on road and will haul heavy loads the 8,600lb kit will reduce sag better...

  • Will The Timbren Suspension Fit a 2023 Ford Maverick With 2" Suspension Drop Installed?
    The Timbren Suspension Enhancement System # T25MR like other systems we carry for your 2023 Ford Maverick are only designed to work with a factory height suspension. You may be able to use some Air Lift 1000 Air Helper Springs # AL42WQ but I will need to know the height of your new rear springs along with the inside coil diameter and distance between the coils to verify the correct kit.

  • Suspension Enhancement Kit that Fits 2023 Ford Maverick FWD
    At this time it is only listed as a fit for the AWD models. The Air Lift air bag kit part # AL57JQ is a fit for the FWD models though and would work great.
