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.

Have seen numerous references to the mysterious "RAS" on several F150 forums- I tow a 6000# travel trailer, the truck does an excellent job pulling it, but I kept experiencing "porpoising" of the trailer following subtle highway undulations. Spent about 45 minutes installing, and other than raising the rear bumper about an inch and a half, the RAS did not change the empy ride of the truck. Just completed a 750 mile road trip pulling the trailer and I have to say the truck has never felt so planted. Easily self-installed (I'm over 70 yrs old) in under an hour, and in my books, worth every dime. If you own one of the modern "half ton" trucks and tow a trailer occasionally, you need this addition.

I installed RAS on my Ford F 150 it was easy to install and took less than an hour! I haul a 33’ half ton fifth wheel camper. Everything handled very well as I drove from NY to Florida. The truck also rides very smooth without the camper! I would recommend this product to anyone who is hauling a trailer!!

Installed the RAS on my 23 f150 tremor, absolutely improved the ride on the rough country roads that I travel daily. No more rear end hop,much more stable. No more excessive squat with my 8000lb trailer hooked to the truck. Could not be happier with the added capability, and improved ride this system gave my truck. I'm 67 and it took me about a hour and a half to install.,no problem. I highly recommend this system if you tow any thing, or travel rough roads frequently in a f150 Ford!

Installed these after a long roadtrip from Texas the Grand Canyon. The added weight from my overlanding gear had my truck squatting pretty bad enough to ruin my front tires. Installed the RAS and got it back to level. Rides great as always and handles the additional weight from my gear perfectly.

They do seem to help with Bunnyhop, on washboard Roads. They do help a little with side to side sway with my 2000 pound camper. If you have airbags, you may have to do some modification of The mounts which hold the airbags. That can be a lot of fun. Overall seems like a good product, and it’s made fairly beefy, easy to adjust.

My 2021 King Ranch PowerBoost has a max payload of 1316 lbs (very low for a new truck) and I needed more assurance towing our 2022 Rockwood Minilite 2509S.Rockwood Minites are notorious for heavy tongue weight (850lbs RAW for a 6360 lbs trailer). I am running an E2 WDH 10,000lb and even though the hitch height is perfectly set (before adjusting the bars and washer), there is quite a bit of read sag, almost to the bottom.Simply put, I needed more assurance for the rear axle weight and support than the 2 leaf springs FORD has decided to move to with their ‘Max Trailer Tow Package’ and #7350 GVWR package.I swapped out the FX4 front and rear shocks for FOX 2.0 Ford Tuned from TC Customs, upgraded the tires (275 60R20) to an E Load tire (295 60R20). Now with my tire PSI set at 60 cold (max is 80), I needed more safety. Enter the RAS.I talked to RAS support and with the YHD they said max space can be set to 2.5mm, or a nickel and a dime thickness, which I did.Install was very easy, the added bump stop relocaters are helpful as well since the 2021 has the auto level headlight sensors on the rear drivers side axle that the RAS would have had issues with for the bump stop.Now loading up my trailer, tongue weight and WDH fully set, my front and rear wheel wells are at 40 1/2 (even) and the front axle has gained 40lbs over unloaded weight. The rear is still holding 600-700lbs but with the RAS I am towing with confidence and control.I am also added Timbren SES in place of the Stock Bump Stop for added towing comfort and control.If you are driving a 2021 F150, I highly recommend you install the RAS even if your towing is light.Loaded and unloaded the driving, comfort and control is vastly improved.Highly recommend 10/10.

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.
