Original (RAS®) RoadActive Suspension 3611-YHD | Fits Ford F150 4WD 2009-2025

2019 Whippled F150 5.0L. Bilstein 5100 shocks all 4 wheels. Truck sat level pre Roadmaster. I purchased the HD version. Installation was a breeze. Took about 2 hours taking my time. Wow! My truck rides so much nicer and gained 1.5 inches of lift in the rear set with black disc. I like the little rake it brought back to the truck. With this system I can barely tell my 26 foot, 5000lb travel trailer is on the back. No sway, bumps are one and done, no bouncing. It made the ride and handling about 50% better all the way around. Best of all no hop and zero axle wrap when I launch it. The truck hooks right up! Imo these work better than traction bars without sacrificing ground clearance. For 550 bucks this took care of all my issues I wanted to solve. Only con was my hands got dirty. Get long jack stands if you don't have them. Oh USA made and 3 year warranty too! Just get them and you'll be very happy.

WOW! Believe every word of the hype. My 2016 F150 felt a little bouncy with a full bed, wasn’t really over the top but I carry a decent amount of tools and boxes back there so it was always a little unsettled. My tools are just heavy enough that it took the rake out of the truck and made it ride really rough over uneven surfaces or bumps.The RAS sorted it out perfectly. I used the black disc assuming it would be best because I always have weight in the bed. It takes a second to get used to, but that’s honestly because of how strangely smooth it rides. It’s very obviously still a truck, don’t get me wrong, but it fixed the ride height and really settled the rear end down.Took about 2 hours but that’s with me basing it off videos I’d watched weeks ago and setting one of the brackets to the wrong hole initially. Use the 3rd one from the end, otherwise the spring will rub against the rebound clip. Otherwise it was a breeze.For my 2016, the bump stop spacer/relocation puck didn’t have roll pins in it, but it sat flush and tightened down nicely, I see no problem with it because you’d really be doing something silly if you ended up on the bump stops with this kit installed anyway….Worth every cent! Don’t buy the fakes. These springs are under a LOT of tension, do not chance it. Those Chinese fakes will break, violently.

This was a piece of cake to install with a little patience and a couple of hours. We hauled a 25FB Airstream with a 2024 F150 Lariat and didn't have any issues on a 6 hour drive. No dog wag or weird sway at any point. It felt very secure and solid and it kept the truck looking level.I would definitely recommend!

This does exactly what it is intended to do. It’s built very well and is super easy to install. The biggest thing I like about this is the stop of wheel hop/ bed shake. With the smaller disk it brought my rear end up 3/4” and when I load the bed down it’s hardly squatting. With the same load without this the nose of my truck would be sticking up. I don’t know if this is my fault from install or my fault for flexing my truck too much for this kit but I noticed after my first camping trip with this the part that bolts around the leaf blocks was bent and after further looking I found out that when I flex the truck enough that it makes contact with the sides of my bump stops. Both sides are bent and I followed the instructions and YouTube videos during install so I’m not sure how I could have messed up there. The road to my camp spot is pretty rough and has a lot of pot holes and articulation to get to it. And while I’m there I like to have fun with the truck so I’m wondering if I bottomed the rear out sometime and it bent the mount or what but it still works fine and went on another camping trip after that with no issues.

These work well and are built of quality materials for sure. I just feel like they're a little overpriced for what you get.

Installed on a 2016 F-150 SuperCrew 4x4. I was concerned these springs would be too hard and create a jarring ride. I was wrong, way wrong. Stability is improved and the truck feels more planted. Not harsh or jarring at all. I tow a 7000 lb. travel trailer, with an Andersen WDH. The ride quality is very nice and the truck and trailer are level.I was considering Sumo Springs, Tembrens, AirLift and Firestone air bags when I came across the RAS spring kit. I am SO glad that I chose RAS. I have the RAS springs set with the white 1 mm disc. My truck has a 200 lb. cab-high shell and a 100 lb. generator when travelling. The RAS kit raised the height at the hitch 7/8" (22 mm).I like the RAS over the others because it's active all the time with no adjustments or maintenance. I figured the bump-stop replacements when engaged would feel like riding on (wait for it) bump stops. I've had air bags on other vehicles and though they ride nice and serve their purpose, they do wear out and require my attention to monitor pressure.I'm very happy with the RAS Active Suspension kit.

Install my 2023, 150 lariat. Increased Hitch hight the back of the truck, two inches. On minimal setting., loose. For towing my boat. And help with normal everyday bumps. Streets are terrible in Denver. Seems to handle the bumps and potholes better. And curb jumps. Ride feels smoother. Hoping it takes away the highway expansion joint jumps, and the warnout concrete vibration. I tried the Rancho nine stage shocks. Took them off and threw him in the trash. Put the old shocks back on. This seems to be the best effect so far for normal driving. Handles well. Highway rough cement and expansion joints. Hardly noticeable.

This is an awesome upgrade for the rear suspension. I was able to easily tow a 7500 lb trailer without a weight distribution hitch and the truck did not sag at all. Installation was relatively easy, though I do have experience. Took about an hour for 1 person plus a helper (which is very useful). My F150 is 2018 4x4 and has a solid cap on top and a decked drawer system holding tools etc. The truck was barely raked beforehand and now rides like it is empty. No rough riding whatsoever when not towing.
