Overload Automatic Self-adjusting Springs for Pickup Trucks, Stop your truck from Sagging with a Load or Trailer
The airless bag to prevent your sag and improve your ride! For trucks with campers, trailers, commercial bodies and all other loads.
SumoSprings (the world’s first and only “airless airbag” suspension system for trucks and vans) are manufactured from an advanced high grade, closed cell polyurethane foam; ideal for the tough truck underbody environment. The product underwent testing in extreme conditions ranging from blistering US desert summer days to the frigid Canadian winter nights. Combining heavy loads with extreme terrain and temperature conditions over eighteen months of testing ensures their performance in any similar conditions our customers might encounter.
Does your headlights see the stars? Stop the sagging and improve handling. As truck manufactures cut costs, I’m seeing more of them cut the rear stabilizers that used to be standard or part of a tow/camper package. Empty trucks needs anti-sway rear stabilizers for cornering and better control. SuperSprings can do that for you as well as level out your loaded truck. Truck manufactures are also making their rear leaf springs longer, which gives you more sag and lean on curves as well as more twisting of the leaf springs. “Roadmaster are the best torsion stabilizer overload truck springs I’ve tried,” better than helper springs and air bags.
RoadActive Suspension are easy to install, just jack up your truck by the frame and drop on.
Thirty minute install, with just hand tools. Below is install on 2006 Ford F250 with factory overloads.
RoadActive Suspension Truck Helper Springs Review and Comparison
If you’ve read my truck accessory articles before, you know I like extreme tests. I’m trying out Roadmaster overload and stabilizing leaf springs, using a friends 10′ camper and his 1/2 ton truck. Of course we should be using a 1 ton dually but that wouldn’t be an extreme test would it. And then to make the test even more dramatic, we only attached the slide in overhead camper 2/3’rds in the truck bed. Now we have some leverage to put aftermarket springs to the test.
Of course the truck dipped and bucked going down the road. Our test truck was a 1990 GMC 1500 (1/2 ton) with 221,719 miles, so the factory springs are well broke in. GM was the first to stretch out the rear leaf springs for a better ride. Ford did it to the Super Duties in the 99 model and Dodge added 3 inches to their HD 2500/3500 rear leaf springs in 2003. I remember back in the early eighties when the compact trucks, (Ranger, S10, LUV, Toyota) stretched their springs for a dramatic improvement in the ride.
These longer springs do improve the ride, but that extra spring travel from longer factory leaf springs allows the trucks to move more. This makes a big difference with a loaded truck as to how much farther the truck will lean on curves, and bounce out of ruts and washboards. I used a slide-in camper with the test truck because that’s the easiest place to notice the lean. Campers attract side wind like a magnet. The older trucks with a camper didn’t lean much, but now Elvis would be proud with all the hip action from a newer loaded truck! And you know if the rear is moving around the front is trying to overcorrect, so if you don’t get sea sick you do get tired of over steering. Do you think all that motion commotion is hard on bearings, springs and tire sidewalls?
Anti-Sway/Load Boosters for Pickups, Vans, and SUV’s,
Roadmaster also works as a axle stabilizer (anti-sway bar) to eliminate wheel hop.
In use for over 10 years and easy to install with no drilling or welding or sweating. End your trucks nasty habit of wheel hop. |
I have been recommending air bags to slow the spring travel reaction down. But aftermarket air bags as well as the rubber bumper pads for overload springs are drilled and bolted to the side of the C-channel truck frames. The truck manufactures are adding more boxed hydro formed frames to their truck lineup which aren’t to be welded or drilled on. So adding air bags is proving more difficult. Compact trucks as well as 1/2 tons and above are going to the boxed frame. All this is making it harder to modify the rear suspension. But I’m always looking for a better solution. Some aftermarket overload springs can help, some of them will make your truck ride rougher when empty, though and we have come to expect the better car like rides from modern trucks. Other overload systems don’t give you the anti-sway benefits of Roadmaster.
A common correction for leveling a trailer, is weight distributing hitch. Which is good for leveling a rig and transferring weight to all the axles. But taking weight off the rear axle of your truck can cause traction problems when you need traction to get you truck back in line during an evasive maneuver. RoadActive Suspension with a good WDH with built in sway control is the best combination for towing.
“These springs are so easy to install it’s unreal. 20 minutes. Didn’t take the tires/wheels off. All I have to say is that if you’re pulling a LQ gooseneck, you need these springs!!! The truck handles much better, even though it’s a new F350, and it doesn’t squat under the load at all. Amazing. Thanks for a great product.” Deb M.”JUST A QUICK NOTE TO THANK YOU FOR THE SUPER SPRINGS. INSTALLED AND ARE GREAT! WHAT A DIFFERENCE. EVERYBODY SHOULD HAVE THEM.” RON B. MURRAY KY |
Everything clamped into place and ready for action! With the factory spring on top of the axle, there is a bracket shown here that clamps to the factory spring to provide the proper torque. If the factory spring is below the axle, no bracket is required. After the camper test, we removed the camper and tested the empty truck. Dirt roads tend to have washboards and potholes this time of year that shake the dust out of your headliner. The Roadmaster took the wheel bounce out of the washboards and the potholes. I didn’t know they would do that. So they do work as a torsion anti-sway stabilizer too. In the spring when the frost comes out of the ground, road damage can sneak up on you where it wasn’t there when you drove to town earlier. I know I get surprised often and I don’t see the potholes as well as I use to even with my tri-focals. Roadmaster, overload and stabilizing leaf springs, another tool to be safe sharing the road.
Update. Roadmaster does increase the rear spring capacity, but not the GVWR, GAWR, bearing or frame capacity. Most modern vehicles at their maximum factory capacity do tend to sag and be unlevel without Roadmaster because of the softer ride (more wheel travel) engineered into the factory suspension. This causes trailer-towing problems too such as to be unlevel with unequal trailer axle weight, and could cause the rear trailer axle brakes to lock up from not enough weight. Both trailer axles with electric brakes, put out the same braking force amps and if one of the axles has less weight, that same pressure can cause it to lock up and drag a bald spot on the trailer tire. |
RoadActive Suspension Truck Helper Springs Review and Comparison
A vehicle that has rear sag also has less visibility and we know where the headlights are pointing. A rear sagging vehicle can have an effect on steering weight, which can cause oversteer. Sport cars have a tight suspension for better control. The same rule applies to loaded pickup trucks, less suspension movement equals stability. Then when the truck is unloaded, Roadmaster allows the factory leaf springs to return to the smooth ride you came to expect in modern heavy duty pickup trucks.
In comparing Roadmaster, which adjust to load automatically, and air bags, my experience is they ride better than air bags loaded and empty. I’ve had folks replace other types of overload springs with Roadmaster and I haven’t had a customer yet that returned the springs because they didn’t do the job. On dirt roads, Roadmaster will take the wheel hop out of washboards. They work as a stabilizer as well as an overload spring, which surprised me. Air bags put all their pressure in the middle of the trucks leaf springs, all in one spot above the axle and on the side of the truck frame. Roadmaster spread the weight to each side of the trucks leaf springs.
Each model year brings about another truck and SUV brand that is going to a boxed frame. Some boxed frames are hydro-formed, some not. Either boxed frame is thinner than the old standard C-channel frame. The air bag systems have to change the way they attach to the truck frame with large U-bolts. You can install Roadmaster in less than 30 minutes without taking the wheel off. The bottom line is Roadmaster will automatically level out your loaded and empty truck with no need to add an air tank or manually adjust the air pressure.
- Maintains smooth ride when vehicle is unloaded – unlike rigid helper springs and add-a-leaf systems.
- Never needs adjusting like “air systems”.
- Anti-sway feature increases handling stability, driver control and confidence.
- Increases the life of brakes, tires and existing suspension.
“Roadmaster will give you the best support for a load and still have the nice soft factory ride when your truck is empty. Roadmaster is automatic, not leaking air lines or need for a tank. One of the benefits, is the fact that Roadmaster will work as a torsion stabilizer like what a anti-sway bar does. No air bag does that. The longer leaf springs on newer trucks, make the ride softer but also increase the wheel travel and thus sag when loaded and more lean on curves. Roadmaster will control that extra factory spring movement. I like Firestone Ride Rite air bags but they won’t do both, support and improve handling. Which is why I just sell Roadmaster and not, SuperSprings, Ride Rite or Timbren or Hellwing or… Thanks”. loads.
