This is the best $ spent on any truck you’re using for towing or hauling. I’ve spent countless hours messing with airbags, helper springs. This beats them all, never makes a sound, improves daily driving, lifts the rear about 1” and levels the truck with towing. This is my third purchase of these!3319073

Great product, super easy install. got an xtra almost 2" in rear stance but im ok with that. Ive had timbrens for a while now and with the near 10k lb boat i pull(short distances) i need something to stop the bottoming out feeling of timbrens when im hooked up.904862

Great product. Easy to install and adjust. I installed on my 2018 F150. I continually run with a heavy load. Cap, decked drawers and bed slide plus tools and fishing gear. Adding Active Suspension raised my rear up 2” and the front 3/4”. Rides better and looks better. I used 40mm spacing due to the load.1040029

I frequently towa26’ travel trailer. The tongue weight is quite heavy and my F-150 struggled to stay at a proper level even with a WD hitch. The RAS addition has taken care of my issue. The truck and trailer are now at the proper levels according to my hitch recommendations . The trailer has much less whip while in tow3380316

Working with etrailer was superb! The RAS system is exactly what my rig needed, it reduced sag and gave me more control when driving with my 2020 F150 4wd crew and 28’ Jayco 7500 # travel trailer! I would highly recommend the RAS system. Easy to install, love it!3557943

Wait what?!
Should’ve put these on first thing when I got the truck. Raised the rear a little over an inch, unloaded ride improves, and now tows level! No messing with air hoses, or pumping them up, just install and Tighten! Reminds me of accumulators on hydraulic setups, brilliant idea

Ride is good but didn’t quite give me as much lift as I was hoping to get. After about 8 months I lifted axle off ground and readjusted again to installation specs with shim and it seemed to help load carrying capability.3439337

This was a huge improvement on my 2020 F150! Towing is a breeze now with these. I recommend them to everyone I know.3571421

Installed this evening on my 2019 F150 FX4 Crew Cab 5.5 ft bed. On level-ish ground before install the fender well was 39.5 inches from the ground (unloaded). Installed these and set the tension for a 2mm gap with the black spacer in the kit for a 40% increase..... This kit removed a little squat and the fender is now 40.25 inches from the ground (unloaded). Truck rides good unloaded, have not yet pulled the travel trailer with them installed. I will update the next time I tow something heavy that I've towed with this truck before installing these. To set the tension use a 9/16 wrench or socket. The bolt is actuall made for an allen wrench but roadmaster uses silicon to glue what apears to be part of an allen wrench into the bolt. I understand this makes it easier for us to install, but they should use something stronger than silicon as one of mine fell out as soon as I started turning it. See pictures. 850610

I tow a 31 foot trailer with my 1/2 ton. Before adding this product the sway was still noticeable, especially with 30 to 40 km wind gust, even with a Curt 4 point sway control hitch. After adding this product I noticed significantly lower sway and better towing.1064286

I don’t normally post about items I have purchased, but in this case, I had to make an exception. I did a lot of research on helper springs and ways to insure my truck gave me my maximum rating. We purchased this kit and it actually arrived a day early and best of all, the day before we were going to get our new 5th-wheel trailer. My son-in-law helped me install them in under an hour. Unfortunately, I did not measure my height before the install, but it did look like it raised the truck a small amount but that was fine with me. I didn’t notice any difference in the ride. The next day we picked up our new Reflection 150 - 278BH trailer. When we first connected the trailer, the maintenance manager commented “Wow, I really expected to see the back end of the truck drop more”. I told him I had installed this kit and he was very impressed. We had a cold front pushing through and had a 20-25 mph crosswind hitting our new rig as we drove home. Since I had not pulled this rig before, I was a little concerned about how the truck would handle. All-in-all, it handled great and the truck felt secure on the road. You could still feel the wind at times, but I did not feel like the truck swayed as much as I remembered our old truck and trailer. Overall, I am quite happy with this kit. My wife said she didn’t really notice any difference in the ride but she did say she thought our truck now looked a little jacked up without the trailer, but as I said, that’s fine with me.935250

Much improvement with stability on the F150 pulling a 8000lb travel trailer. I would recommend these to everyone pulling a travel trailer with a 1/2 ton3508695

Great product. Installed on my 2018 F150. Really a simple and quick install. Followed the etrailer video. Thanks for providing the video. The instruction sheet provided by RAS is not as thorough as the video.
The install took less than an hour.
Highly recommend this product.3491438

etrailer asked if I would review the roadmaster active suspension kit after a year. Ok, I get a lot of junk email but this impressed me. This shows that they are a stand up company.
I purchased this product to help with the sag I was getting at the hitch.
I read a lot of articles and literature about the sagging issues and almost went with an air system as they are described as the end all be all fix. WRONG!
I installed this RAS on my 2018 F150 and the sag was gone. It has never returned. The trailer rides true behind my truck and my truck rides great when I’m not hooked up.
I have max towing capability with my truck from the factory but I pull a 10,000 lb trailer. Lot of concrete grinding equipment, big vacs, generator and I haven’t had any issues at all.
The Roadmaster active suspension works just as advertised. I’m very happy with the purchase and I’ll do it again on my next truck.959742

Roadmaster active suspension seems to be built very well. I look forward to towing my travel trailer very soon to see if it improves the towing experience.946692

I am a competitive shooter and take my camper to all my shoots. I have a cap on my truck and the decked drawer system. I also carry 400 lbs of ammo at any given time. When pulling my camper on the highway or over bumps and railroad tracks it was kinda scary. This system stopped the squat and removed the sag at acceleration. I installed sumo springs as well (without spacer) for added sway control when loaded down with trailer. The RAS was great right from the start. It reminded me of the 80’s then we would put traction bars on old hot rods to stop rear squat on acceleration. Same kind of feel with my truck. Some much nicer. With the trailer it removed 1.5 inches of squat on the rear and got my front and back within 1” of variance and before install it was around 2.5 to 3. Took only fifteen minutes per side to install once the tires were off. Great product….3161680

The Road Active Suspension is The solution .
2015 F150 EB Max Tow pulling a Lance 1685..
Truck pulls TT with no effort..but was looking for better handling options.
Have many miles without RAS vs Quite a few now with RAS.
The driving and handling is a very welcome improvement… from high mountain passes and roadways to Interstates.. wind… rain … etc
Was contemplating a 3/4 ton… not now.
Easy install.. you won’t be disappointed3222741

Easy Install and everything was in the box. These raised the rear of my truck 1 1/4” and give a stable ride.3207210
by: Dean06/15/2026
Install went smooth, did this myself. Gave my F150 the extra support to be able to tow my half ton rated fifth wheel with the truck sitting level. The unloaded ride is still just like it was prior to install. I used the thin white spacer to set the spring tension.3565433

Installed this today on my 2023 Ford F150 Lariat 4x4 with the tow package. The kit arrived within 2 days of ordering. The box was slightly open but the springs appeared undamaged. I elected to do the install myself and opted to get a 4 ton floor jack to replace my very old 3 ton. I’m very glad I did. After blocking the front tires and setting the parking brake, I loosened the wheels and raised the rear at the differential using a small 2x4 block to span the contact points. I took the wheels off and originally set my jack stands in front of the leaf spring on the frame. Lowering the truck onto the stands was not effective. There wasn’t enough travel to provide relief to the springs. I ended up setting my jack stands on some 1x16 scrap pieces and put them under the spring attachment point. This gave me just enough room on my floor jack to unburden the springs. Once I got over this small hurdle the install went smoothly. This took about an hour to very carefully construct as I didn’t want to drop my brand new truck on the ground. Brand new 5 ton jack stands would have eased my mind considerably. My install includes a spacer for the bump stop to offset it towards the centerline of the vehicle. The instructions weren’t intuitive and it took a few minutes to figure out the bolts. You need to insert the provided bolt into the spacer and attach the spacer to the frame with the original bump stop bolt. It’s the only one you can get a socket on in the depression. The bump stop then attaches to the provided bolt you inserted into the spacer using the provided nut. You will need a deep well 15mm socket for this attachment. Fortunately I had one. I set the spring using the 25% white spacer, reinstalled the wheels and set the truck back on the deck. The truck now sits 3/4” higher in the rear. I drove around and noticed that I was sitting a little higher as the site picture changed a bit. The truck didn’t seem to ride differently empty. If anything it seemed a little more cushioned though no less responsive. I towed my 9000lb travel trailer previously with a Ram 2500 6.7l diesel that had Sumo springs and a WD hitch. I got tired of the cost and maintenance and selected this Ford because it could haul the trailer. I chose the RAS over the Sumo springs because of how much squat I observed when I hooked up the trailer initially. I will update after I tow the trailer. My only concern at the moment is that the bump stop spacer isn’t going to provide enough clearance from the bracket.1708587

This is my second F150 with an RAS installed. With RAS, my 2023 F150 2.7 Supercrew (with HD payload package, rated to tow 10,100#) tows my 6000# Airstream completely level with no squat and no issue when paired with a WD hitch. And yes, I've done the same tow without RAS and would prefer not to do it again. Absolutely an improvement over stock with minimal impact to daily driving. It does raise the rear about 1-2" but nothing the average person notices and I forget about it all the time. I'd like a leveling kit to help raise the front/reduce the rake a bit but then it wouldn't tow level anymore so that's the compromise. The RAS does exactly what it claims to do, at a fair price, and maintenance free (no airing up or down etc.) The only improvement that would be better would be trading up to a 2500 or 3500 but that's not the daily driver experience I want for the 80% of the time I'm not towing. I did buy again when I traded in my 2017 and would buy yet again if I got another half-ton.3321120

Purchased for a 2018 F150 to assist with towing a 6000lb RV travel trailer. The heavy duty model is too heavy duty. With the pre-loading as light as possible, the unloaded ride is stiff. Would recommend the standard model. With the travel trailer (using an Equalizer brand weight distribution hitch), the ride and stability was much improved over just the factory leaf springs. The rear of the truck was raised over an inch. Installation was straight forward. A little bit of guessing as to the pre-tensioning and if they are matched left and right. Would love it if the design could be changed such that it was easy to "snap on" when needed and "snap off" when unloaded. Maybe some sort of lever system would make this possible. Overall, they did what they are designed to do - assist the truck in being more stable when under load and less squat. I ended up trading the Ford for a Toyota which has coil springs so I passed on the RAS to the new owner of the Ford.3311945

I bought these after a 1000+ mile trip towing my trailer (~8000# loaded) with my 2013 F-150 (HD Payload & Max Towing Package). Installation was super easy. I did not need to take the tires off. There was plenty of room to get behind the tires and place and adjust the springs. Once installed they definitely give the truck a rake. I didn't measure pre-installation because I didn't expect the lift to be so great. I used the black disc to adjust the springs.
It's not too extreme but you can definitely see a difference compared to stock.
As you can see in the pictures, with the springs the drop with a trailer attached is greatly reduced and the truck sits level. Towing was great. I used a WDH before and being able to with springs only and a sway bar is pretty nice. Drop with trailer attached is only about 2.5 inches (see pics)3185686

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.
