When towing a trailer or hauling gear, rear-end sag can throw off steering and braking. The RoadActive Suspension custom leaf spring enhancement kit adds up to 3,000 lbs of load support by converting factory leaf springs into a mechanically active system. The variable-rated coil tension springs automatically adjust to the load, keeping the ride level and stable whether towing, hauling, or driving empty. With axle wrap, wheel hop, and bottoming out eliminated, your truck stays composed and predictable under pressure.
Most suspension helpers are either too soft or too stiff depending on the weight. This setup reacts instantly to the load—coils engage when weight is added and disengage when unloaded, so the ride stays smooth without extra stiffness. The variable-rate design boosts traction during acceleration and braking while keeping handling steady over rough roads. It’s a simple mechanical system with no air lines or maintenance needed once installed.
Heavy trailers or bed loads can cause sway and body roll that make driving stressful. This system strengthens the leaf springs to control side-to-side movement before it starts. The result is less sway on curves, better stability in wind, and fewer rocking motions when passing semis or navigating uneven terrain. The truck feels planted through every turn, even with a camper or heavy trailer behind you.
Each unit is made from high-grade alloy steel with an epoxy e-coat for corrosion resistance. The end brackets have a salt spray rating of more than 800 hours to stand up to water and road grime. Once bolted in place under the leaf springs using existing U-bolts, no drilling or welding is required. It’s a durable, maintenance-free setup designed to handle years of real hauling without fussing with leaks or adjustments.
During installation, the coil tension can be set between 25% and 40% using included spacers to match your hauling needs. Each side can also be adjusted independently to correct uneven loads like campers or toolboxes. This flexibility gives you a balanced stance and confident handling no matter how your cargo shifts or what you’re carrying.

Hi everybody. Andy here with etrailer.com. Let's take a look together at this road active suspension custom leaf spring heavy duty enhancement kit. Now this kit is designed to fit your 2015 to 2018 Ford F150 two wheel drive and on custom fit parts such as this kit, I do recommend taking advantage of our vehicle fit guide. Just insert the year, make and model of your vehicle and our our fit guide will confirm if this kit will work for you or if we have something comparable that will work for you. Now, as you probably know when towing or hauling a heavy load, you may encounter a number of problems that can make the driving experience difficult or even dangerous, such as sway, body roll, or bottoming out.
When your vehicle is weighted down, your factory leaf springs can't counteract these problems to the extent that they are supposed to. The weight will overpower those leaf springs and cause them to flatten out. When that happens, they're not gonna be able to support or stabilize your truck effectively. Additionally, because your factory leaf springs are passive, you won't, they won't begin to tackle problems such as sway until those problems have already started. Now this kit is going to convert your trucks factory leaf springs into a mechanically active suspension system.
It's going to actively suspension your leaf springs for improved ride quality with or without a load. And this all in one suspension system is going to improve stability, handling, and control. It's going to eliminate axle wrap, wheel hop, and bottoming out and it will reduce dangerous sway and body roll when you're cornering. It will even keep your ride level when you're towing or hauling a heavy load, improving your traction while braking and accelerating. It does use the variable rated coil tension springs, which will automatically adjust to your truck's load.
They activate immediately to support the extra weight and they will disengage when unloaded allowing your leaf springs to perform as they are intended to do. Now these can be adjusted during installation to accommodate your towing or hauling needs, and they are independently adjustable for side to side leveling of any off-center loads. These will extend the life of your factory leaf springs, your shock absorbers, shackles, and even your tires on your truck. These are made here in the USA and they are constructed of a durable epoxy, e-coated steel, and the corrosion resistant brackets and the ends of each unit have a salt spray rating of more than 800 hours. Now this is going to be a relatively easy bolt-on insulation, so that's what's nice about this system is there's no drilling, cutting, or welding required.
And as you see there on the photo that I put on your screen, the unit is the eye hook bracket will wrap around the top of the factory leaf spring eye and then the unit will secure under your leaf spring and around the factory U bolts. Now this is going to arrive just as you see it here on my table before me. They're going to arrive fully assembled. The hardware is included, instructions are included to guide you through that installation process. These are gonna be maintenance free and adjustments and monitoring aren't going to need be needed once they are installed. Now I think I failed to mention that the weight capacity is 3000 pounds. However, an important note to make is that these will not actually increase your truck's vehicle weight carrying capacity, so you wanna make sure that you don't exceed your manufacturer's recommended weight carrying capacity on your F-150. Well, I think that's gonna wrap up our look today. I do hope that our time together was helpful for you. Again, my name is Andy. Thank you for joining me.

I still think these springs are one of the best aftermarket purchases Ive made for this truck. Obviously, different trucks will give different results, but for me not having to hassle with a WDH I just use a sway bar makes all the difference. Before the springs, I would towwith a WDH and sway bar and constantly felt the trailer behind me or felt I was floating in the front end. These springs have *almost* completely eliminated that. Amazing difference.

1-year comments - As mentioned, traded the F-150 for a Tundra. RAS did make a noticeable difference in handling of the travel trailer and body roll of the truck even when not towing. I can only guess but would recommend going with standard model over HD as ride was stiff with light load in the truck and not towing. Upgrading the suspension on the travel trailer made the most difference in overall stability. New slightly higher rated leaf springs, Morryde equalizer, and wet bolts, combined to greatly lessen the body roll of the trailer which led to a much more stable drive especially with side wind loads. RAS is nice and worked to give the F150 more strength for when towing or when more heavily loaded. So still give it 4 stars.

Really glad to hear that, James! The RAS is really good at its job for sure! Thanks for sharing the photo of your set up - the Airstream and truck are looking mighty fine! When's the next camping trip?

The RAS is a great addition to the stock leaf springs on my F250. I have in the past year towed my 36’ Jayco travel trailer from Ontario to Nova Scotia and from Ontario to South Georgia. About 1700 miles total. From the 400 series highway the Trans Canada highway and the inter state highways the RAS along with the Fast Way E2 weight distribution and sway control system, my bumper tow is locked in and stable. The RAS reduces body roll on the tow vehicle eliminating the magnifying effect body roll has on the sway of the trailer. No white knuckling in cross winds or passing transport trucks on the interstate highways. Highly recommend to compliment the rear truck springs for towing heavy loads.

Glad we had the part to get rid of the sag Allen! What kind of system do you have in the bed?

Been a year now and I’ve pulled my 9200lb arctic fox trailer from Illinois to Halifax NS and back. The tongue weight was 870lb and the payload weight of the truck was maxed out from the Ford towing program and the CAT scale. The weight distribution hitch and this allowed for a very smooth ride even in the rain. The only issue was when the crosswinds were more than 10mph. The winds coming home out of Canada were 30mph and that was anxiety inducing especially coming across the mountains. Without the RAS I wouldn’t have even tried it. This was necessary to level the truck and have it track. I bought the trailer TPMS also because a blowout at that weight leaves no margin for error. Get the RAS for your light duty truck but don’t ignor your max weights. The rear axle weight was the limiting factor without the RAS and the WDH. The only drawback is the Ford headlight leveling sensor on the rear drivers side axle sits awfully close to the clearance of the shock and careful positioning is called for.

Its been a year since I installed my Roadmasters. Would I do it again? Absolutely! They have made my travel trailer pulling such a better experience. In addition, my daily commute has been a pleasure as well.

After a year of use , these RoadMaster 3611-HD active suspensions are still the best addition to my trucks performance. The streets of Houston are brutal and these active suspension breeze through them. I have 354000 on this truck and if I ever get another, this Active Suspension will be the first addition. Hands down!

Wow, that is awesome to hear a product really deliver on what its made to do! Youre a competetive shooter? Thats so cool. I could never do that - Im such a bad shot I wouldnt hit water even if I fell out of a boat. Do you travel across the country or do you stay more local?

Its been really wonderful. 10k 5er on my 07 2500hd classic ccsb and I can definitely notice an improvement in handling, including less porpoising. Towed it a couple times since, including a 7 hour drive. Very happy. I recently replaced the old wornout front bumpstops with sumo springs monsters and saw additional improvement. Neither hurts the unloaded ride, just better all around!

It has been a year now since I installed the Roadmaster Active Suspension system on my 2018 F150. We pull a 30 ft travel trailer from Wisconsin to Alabama.Last year the roads became very slippery when we encountered a rain snow mix. The truck and trailer tracked perfectly. I just hooked up the rig yesterday to take the same trip, leaving tomorrow. The truck definitely handles better with the RAS. Im glad I installed it and am sure it will last for years.

Great, these springs gave my truck stability and the ideal ride height I needed to pull my trailer with minimum sway. I would definitely purchase these again.
