If you drive a 2025 Ford F-150 Tremor or F-250 Tremor, you already know these trucks are built for serious work—whether that means towing fifth-wheel trailers, hauling heavy gear, pulling boats, or tackling off-road terrain.
But even a capable factory suspension can experience one common issue: truck squat. If you are searching for how to fix truck squat on a 2025 F-150 Tremor or wondering whether air bags will fit your truck, this guide explains the causes, fitment considerations, and installation precautions you should understand before upgrading.
When towing or carrying heavy loads, trailer tongue weight and cargo can compress the rear suspension. Excessive rear sag may affect steering response, headlight alignment, and vehicle stability. Before choosing a suspension upgrade, identify your truck's exact configuration and confirm that the selected kit is compatible with its factory suspension and any off-road modifications.
What Causes Truck Squat on Tremor Trucks?
Truck squat occurs when the rear suspension compresses under the weight of cargo or trailer tongue load. This reduces rear ride height and can change the vehicle's front-to-rear stance. The effects may become more noticeable when towing heavy trailers, carrying equipment, or driving over uneven terrain.
Although some suspension compression is normal under load, excessive rear sag can reduce available suspension travel and affect handling. Proper cargo distribution, appropriate trailer loading, and a compatible supplemental suspension system can help maintain a more suitable ride height. Air bags do not increase the truck's factory payload, GVWR, GAWR, or towing capacity.
The Right Fix: Air Bag Suspension for Tremor Trucks
A properly matched air bag suspension system provides adjustable supplemental support to help reduce rear sag and maintain ride height under changing loads. Air pressure can be adjusted according to the load and the manufacturer's specifications, making air bags useful for trucks that alternate between everyday driving, towing, and hauling.
However, not all kits are interchangeable. Installing a universal or incompatible system can introduce problems such as air spring misalignment, insufficient clearance, premature wear, and inconsistent suspension performance. A kit must match the vehicle's frame, axle, spring configuration, and available suspension travel.
RETRUE offers a range of Ford air suspension kits for different truck generations. Before ordering a kit for a Tremor, verify the exact trim, model year, drivetrain, factory lift, and suspension configuration with RETRUE. Do not assume that a product listed for a standard F-150 or F-250 automatically fits a Tremor model.
Why Tremor Trucks Require Careful Fitment Checks
Compared with standard truck configurations, Tremor models may have different ride heights, off-road suspension tuning, jounce bumper clearances, and underbody components. These differences can affect the available mounting space and the amount of suspension travel a supplemental air spring can accommodate.
A poorly matched kit may interfere with skid plates, exhaust components, or other underbody parts. Incorrect positioning can also cause an air spring to rub, fold, or become pinched during suspension compression. Before installation, confirm that the air springs and brackets have adequate clearance throughout the suspension's intended range of motion.
A suitable supplemental air suspension system should support the rear suspension without restricting its intended operation. If your truck has a factory lift or aftermarket suspension modifications, confirm compatibility before purchasing and installing any kit.

Position the air springs and brackets according to the supplied instructions. Verify correct alignment and check for interference with the frame, axle, exhaust, and other components before tightening the hardware.
Step 4: Route the Airlines and Wiring
Route the airlines away from heat sources, sharp edges, and moving suspension parts. Secure the lines without creating kinks or restricting normal suspension movement. Follow the instructions for any electrical connections if an onboard compressor is installed.
Step 5: Install the Inflation Valves or Controller
Install the supplied inflation valves or compatible controller in the specified location. Make sure the valves are accessible and that the airlines are securely connected.
Step 6: Inflate and Test for Leaks
Inflate the air springs to the pressure specified by the manufacturer for the initial inspection. Do not automatically use 50 PSI as a universal setting. Check all fittings with a soap-and-water solution and correct any leaks before operating the vehicle.
Step 7: Verify Suspension Clearance
Complete the manufacturer's required clearance checks before towing or hauling. Confirm that the air springs remain properly positioned and do not contact nearby components throughout the permitted suspension movement.
Expected Results After Correct Air Bag Installation
A compatible, correctly installed air spring system can help reduce rear sag and maintain a more level ride height when the truck is carrying cargo or towing a trailer. Appropriate suspension support may also help maintain more consistent steering response and vehicle balance under load.
Actual results depend on vehicle configuration, cargo distribution, trailer tongue weight, and pressure settings. Air bags do not independently eliminate trailer sway or correct an overloaded vehicle. Proper hitch setup, balanced cargo, suitable tires, and compliance with factory weight ratings remain essential.
Maintenance Tips for Long-Term Performance
Regular maintenance is important for trucks that frequently tow, haul, or travel on rough terrain. Inspect air springs, brackets, airlines, fittings, and mounting hardware for wear, looseness, abrasion, or damage. Remove accumulated dirt and road debris, particularly around areas where the air springs may contact nearby components.
Check air pressure before towing and adjust it according to the load and the manufacturer's instructions. If pressure drops unexpectedly, identify the cause rather than repeatedly adding air without checking for leaks. Follow the manufacturer's inspection and maintenance schedule, including any specified hardware rechecks after installation.
