There’s a lot more to towing than raw horsepower. Ask anyone who’s hauled a heavy trailer across mountain passes or through a Texas headwind — it’s all about balance, gearing, and control. Lifted truck owners often ask how their suspension, tire size, or gearing affects towing. The truth is simple: a lifted truck can tow exceptionally well if engineered correctly, but the physics behind it must be understood and respected.
At Lifted Trucks, we build trucks that don’t just look the part — they perform. Here’s what every enthusiast should know about how lift kits, tire size, and axle ratios work together when it comes to towing performance.
Understanding the Forces at Play
Towing is essentially a tug-of-war between weight, friction, leverage, and mechanical advantage. When you lift your truck or change its rolling diameter, you alter the balance of those forces. Even small changes — like switching from a 33-inch to a 37-inch tire — can have measurable effects on torque, braking, and stability.
When you lift a truck, you raise its center of gravity. That means more weight transfer under acceleration and braking, and more leverage acting against your suspension and hitch point. None of this is inherently bad — it just means the setup has to be engineered with towing in mind.
Lift Kits and Towing: What Really Changes
A lift kit alters the suspension geometry and, in many cases, the hitch height. That matters because trailers are designed to sit level. If your hitch is too high, the trailer tilts downward toward the rear, reducing tongue weight on the hitch and causing sway or fishtailing.
To tow safely with a lifted truck, the key is hitch alignment and load distribution. Adjustable drop hitches or weight-distributing systems are essential to maintain level towing angles.
Higher lifts also increase leverage on the rear suspension. That’s why air-assist springs, upgraded leaf packs, or progressive-rate coils are so important. These components restore balance under load and prevent rear-end sag that can lead to wandering or unsafe handling.
At Lifted Trucks, every towing-capable build is engineered to maintain optimal ride height and suspension compression, even when loaded.
Tire Size: The Hidden Torque Thief
When you go to larger tires, you’re increasing rolling diameter — which directly affects your effective gear ratio. Think of it like riding a bicycle in a higher gear: it takes more effort to get moving, but you can maintain higher speeds once rolling.
The same principle applies to trucks. Larger tires reduce the torque available at the wheels, making acceleration and towing feel sluggish unless compensated by lower axle ratios (numerically higher).
For example:
-
Stock tire size (33") with 3.73 gears = balanced performance.
-
Larger tire size (37") with 3.73 gears = 10–12% torque loss at the wheels.
-
Re-gearing to 4.56 or 4.88 restores that torque and throttle response.
Proper re-gearing also helps prevent excessive transmission downshifting and heat buildup under load — two leading causes of transmission wear in towing applications.
Axle Ratios: The Backbone of Towing Power
Axle ratios determine how many times the driveshaft turns for each wheel rotation. The higher the ratio (e.g., 4.56), the more mechanical advantage you have — which means better low-end torque and smoother towing performance.
When trucks are lifted and fitted with larger tires, maintaining proper gearing is critical. A truck that’s geared too tall will struggle to maintain speed on inclines, constantly downshift, and burn more fuel. Conversely, a properly geared truck feels stronger, cooler, and more efficient under load.
At Lifted Trucks, we tailor gear ratios to match your lift, tire size, and intended use. Whether you’re hauling a boat, car trailer, or travel camper, we ensure your build has the ideal balance between torque and cruising efficiency.
The Role of Weight Distribution and Trailer Setup
The best tow setup keeps 10–15% of the trailer’s weight on the tongue and distributes load evenly over both axles. Lifted trucks with high rear hitches often suffer reduced tongue weight — which can lead to sway or instability.
A properly matched drop hitch, load-equalizing system, and trailer brake controller restore control and stability. In many of our builds, we recommend upgraded rear sway bars and airbag suspension for towing consistency across all terrains.
Aerodynamics: The Unseen Drag
A lifted truck sits higher and pushes more air, which increases wind resistance. When towing, that aerodynamic drag multiplies — especially with boxy trailers. The key is maintaining balance between lift height and purpose. A 4-inch lift with 35s can still tow beautifully with the right geometry, while an 8-inch lift may need additional stabilization to keep highway manners in check.
We test our towing builds under load to ensure predictable braking, steering, and highway performance.
Braking and Stopping Distance
More weight, larger tires, and altered suspension angles mean more braking force is required. Factory brakes can struggle when towing heavy loads on lifted trucks.
Upgrading to slotted rotors, performance pads, and stainless steel brake lines dramatically improves stopping power.
Transmission Cooling and Monitoring
Towing generates heat — and heat is the enemy of transmission longevity. Larger tires and taller gearing can force your transmission to work harder, especially on long grades.
A high-quality auxiliary transmission cooler is a must-have for lifted trucks that tow frequently. At Lifted Trucks, we often pair this with real-time monitoring solutions so owners can keep an eye on transmission temps during heavy towing seasons.
Putting It All Together: Engineering for Real-World Performance
When done right, a lifted truck can tow with confidence, power, and control that rivals — or even surpasses — stock trucks. The difference lies in tuning and geometry:
-
Correct axle ratio to match tire size
-
Reinforced suspension to handle tongue weight
-
Proper hitch height and distribution setup
-
Upgraded braking and cooling systems
At Lifted Trucks, we don’t just build trucks that look powerful — we build trucks that are powerful, engineered from the ground up for capability and control.
