How much lift does an add-a-leaf add?
What Do Add-a-Leaf Kits Actually Do? Add-a-Leaf kits adds a 2-3†lift to your vehicle. The additional leaf spring provides more tension to the existing leaf springs making it that much more shock absorbent from the bumpy roads, tough terrain and heavy loads.
By adding an additional long, full-size leaf to the existing leaf stack or by adding an extra leaf to each rear leaf spring, you can increase the load capacity and raise the height of the vehicle up to a few inches. If your truck is sagging in the back, you know you need to bolster its carrying capacity.
WHAT is an Add-A-Leaf? An Add-A-Leaf is an extra leaf added to a leaf spring pack. Added leaves are installed to increase vehicle carrying capacity or to reduce sway by creating a firmer ride. They can also be used to increase the ride height of your vehicle.
Does Adding Leaf Springs Increase Load Suspension? The purpose of the installing a new leaf isn't to increase the capacity of the load that a vehicle can handle. Vehicles are designed to only carry a certain amount of weight before things such as tyres, axles and the overall suspension system is compromised.
Lift Your Truck Without Spending A Lot
Do you want to add some lift to your truck or SUV, but don't want to spend a lot of money? Add-A-Leaf kits are answer to your problem. These leaves can be easily added to your OEM leaf spring to give your vehicle a few extra inches of lift.
Increase Rear Ride Height and Towing Capacity for your F150
This pair of leaf springs install directly into your F150's stock leaf pack without any drilling, cutting or trimming, and add up to 950lbs of load support to your truck.
How Much Do New Leaf Springs Cost? The average cost to replace leaf springs ranges from $450 to $790 if you hire a professional. These estimates include the cost of labor in addition to the springs and parts. The cost of the installation alone could range from $95 to $170 depending on where you go.
For leaf springs (a common rear suspension for trucks) you could simply add another leaf, or use 'spring helpers' that bolt on to your existing springs to add tension and strength. Coil springs are more common on the front end and can be reinforced by fairly inexpensive, easily-applied supports.

Add a leaf can increase capacity (up to 800 lb) but will affect the unloaded ride quality. Air ride is always inflated, which can affect the unloaded ride quality.
How much weight can a leaf spring hold?
There is usually two capacities listed on a leaf spring. The spring capacity and the axle capacity. For the 4-Leaf Double-Eye Spring # SP-212275 that you referenced it has a spring capacity of 1,750 lbs meaning that the individual spring can handle 1,750 lbs.

The only way to boost the payload rating is to take weight off the truck: removing the rear seat or bumper, using lighter wheels and/or tires that meet gross axle weight rating requirements, and so on.
Many thin leaves mean that each leaf can have a lower spring rate, which results in a softer ride. A spring pack with many thin leaves is thicker overall than one with a few thick leaves. That is a good thing in a spring-over application since the main leaf is flatter giving a better ride.
Can adding an airbag to your existing suspension allow you to carry increased payloads or tow heavier trailers? The simple answer is, no! It's important to remember that the addition of any airbag system does not allow higher payloads or towing capacity to your current vehicle.
Keep a lightweight jackstand with you in the truck. Then you can use your bottle jack to jack the truck up slightly from the leaf spring, place the jackstand under the axle, then move the bottle jack under the axle and keep jacking it up.
Will Helper Springs Lift My Truck? No, helper springs are not designed to lift your truck, but they are designed to level out the back of your truck.
A leaf spring can either be attached directly to the frame at both ends or attached directly at one end, usually the front, with the other end attached through a shackle, a short swinging arm. The shackle takes up the tendency of the leaf spring to elongate when compressed and thus makes for softer springiness.

You cannot increase the towing capacity of the F150, technically. What you can do is add hitches, air springs, and bump stops to improve the towing performance of your truck. Towing mirrors also help improve your drive.
Can you add leaf springs to F250?
Add-a-leafs for the Ford F150, F250, Ranger and other models are the economical solution to adding lift to your Ford truck. The add-a-leafs will simply insert into your existing Ford leaf spring and once installed, they will give you added height and weight capacity.
Over time, leaf springs can corrode or become fatigued. The cause of fatigue is often a combination of exposure to elements and normal wear-and-tear from hauling heavy loads.
With an increase or decrease in the amount of air pressure in each bag, you can adjust the suspension for rides with lights loads, heavy loads or no load at all. People often ask — do helper springs really work? The answer is yes, absolutely.
Stabilizer links are replaceable as a single part and generally do not require being replaced in pairs. Leaf springs may need to be replaced in pairs if: a match to the undamaged leaf spring cannot be identified or obtained. the undamaged leaf spring appears to be aged or worn."
But for vehicles that are used in heavy-duty applications, standard leaf springs will reach the end of their lifespan faster. If this is the case, it's worth upgrading your leaf springs to heavy-duty ones, too. With heavy-duty leaf springs, your vehicle can carry more weight with less wear.
The smoothest riding shocks you can get would be ones identical or nearly identical to factory tuning, typically something like the Bilstein B4 series, KYB Excel-G Series, or Monroe OE Spectrum. All of these have the most forgiving valving for road handling and comfort.
In an older, heavily driven automobile, the leaf springs may not last as long. In contrast, a well-maintained vehicle's leaf springs can last well over 100,000 miles. On average, a set of leaf springs might last about 200,000 miles.
A helper spring is a suspension enhancement product engineered to enhance, support, and help various types of original equipment suspension. There are two basic types of helper springs: steel springs and pneumatic springs, more commonly known as air springs.
How Should Leaf Springs Look? Leaf springs can be found on the front or rear end attached to either the bottom or top of the axle of cars, trucks, vans and SUVs. It looks like different sizes of bowed, narrow strips of steel stacked together. This part is created to absorb the gravity of an excessive amount of weight.
A 2500HD has five leaf springs, four mains and one overload positioned under the mains with no bump stops.

Investing in the right helper springs enhances or replaces factory components, increases payload and towing capacities, decreases or eliminates sway, improves ride quality, and limits wear and tear on the vehicle.
In simple terms, a constant load spring is one that will hold a constant load at a specified height. So when we say 'constant 300kg' we're saying the vehicle will be 40mm above standard height, when 300kg is in the rear of the vehicle.
Since the axle will have two leaf springs, one on each side, the weight rating of the leaf springs will be 1/2 of the weight capacity of the axle. For example, a 3,500-lb axle will use two leaf springs rated at 1,750 lbs each.
More robust leaf springs will last longer than a standard solution when seeing regular use as a tow truck and will provide a safer, smoother ride hauling or pulling to capacity. One drawback of heavy-duty leaf springs occurs if you are routinely riding with an empty load.

What happens if you exceed the payload limit? The extra weight puts more strain on the engine, transmission, suspension, brakes and tires, and can lead to repair problems. Overloading a vehicle, for example, will increase braking distances and increase wear on brake pads and rotors.
- Honda Ridgeline: 1,500 – 5,000 lbs.
- Nissan Frontier: 6,250 – 6,720 lbs.
- Toyota Tacoma: 3,500 lbs – 6,800 lbs.
- Chevrolet Colorado: 3,500 lbs – 7,000 lbs.
- GMC Canyon: 3,500 – 7,000 lbs.
- Ford Ranger: 3,500 – 7,500 lbs.
- Jeep Gladiator: 4,000 – 7,650 lbs.
Payload capacity is the maximum amount of weight your vehicle can safely carry and cannot be increased with a weight distribution hitch.
Yup. The springs will become harder over time due to the constant flexing.
Why does my truck ride so stiff?
Rough, bumpy rides can be due to bad tire alignment, incorrect air pressure – too low, too high, different pressures in each tire – or even the tires not being mounted properly. Worst case scenario could be the rims themselves have become damaged or warped.
...
Other tell-tale signs of worn-out leaf springs include:
- Uneven tire wear.
- Frequent bottoming out.
- A bumpier, less comfortable ride.
- Leaning to one side.
Truck air bags give you excellent support, better handling, and a whole lot of confidence, but they do not increase the gross vehicle weight rating (GVWR) of your truck. You still need to pay close attention to that rating while loading up to ensure you do not surpass its max abilities.
Or “do airbags lift your truck?” and the answer to that question is no. Airbag suspension systems are not the same as a lift kit, and both serve different purposes. An airbag suspension system is easy to install and attaches to holes that already exist in your truck frame.
Air bag suspensions are used to achieve smooth ride quality by replacing the conventional steel-spring suspension in heavier vehicle applications like trucks, tractor-trailers, passenger buses, and even passenger trains.
How Much Do New Leaf Springs Cost? The average cost to replace leaf springs ranges from $450 to $790 if you hire a professional. These estimates include the cost of labor in addition to the springs and parts. The cost of the installation alone could range from $95 to $170 depending on where you go.
Safety:Helper springs will give you more control over your loaded vehicle, increasing safety and driver confidence. What helper springs cannot do: Lift the vehicle: Helper springs are not designed to be used as a vehicle lift. In fact, they do not affect the unloaded ride height.
Over time, leaf springs can corrode or become fatigued. The cause of fatigue is often a combination of exposure to elements and normal wear-and-tear from hauling heavy loads.

Do helper springs actually work?
With an increase or decrease in the amount of air pressure in each bag, you can adjust the suspension for rides with lights loads, heavy loads or no load at all. People often ask — do helper springs really work? The answer is yes, absolutely.
As for helper/overload springs, they don't change a truck's GVWR or max cargo carrying capacity—they just help level the load and take the sag out of the tail.
As Load Hog® helper springs are fully adjustable, many 4×4 owners fit them to raise the ride height of their vehicles for more ground clearance. The increased ride height is adjustable up to around 40mm. Pickup owners can also lift their vehicles to fit larger tires.
