🚛 Roadmaster Active Suspension #3611-Y: Perfect Fit for 2011-2012 Ford F-150 #MK3-XXY Review

I'm towing a 38ft trailer and it stopped bouncing after the overpasses. Made the ride more manageable. Since installing them, I feel a lot more relaxed behind the wheel.

My 4X4 3.0L F-150 double cab rear w/ towing kit hopped a bit (porpoise) with a 6000lb trailer. The trailer is now completely stable with no bouncing or swaying, and the truck is level with the 1000-pound drawbar and WD hitch. With no load, the truck feels great and is very comfortable to drive. Outstanding product. You will not regret it.

My TT toy tractor's nose weight is near max and I'm squatting half a ton. I have a lot of engine power but no payload. I decided to try them via the airbag system. So far I'm very pleased after a 5 hour drive through windy west Texas to New Mexico. My butt has grown from 3.5 inches squat to 1 inch. The front stroke has been increased from 2 inches to 3/4 inches. My TT pulls much better after installation. My ride without my TT is better too. I highly recommend trying these out. The installation

2021 Ford F-150, 4x4, 3.5 Twin Turbo, Ecoboost. 10,000 lb semi-trailer, tongue weight 1500 lb. I've tried airbags which worked fairly well but still resulted in a bumpy ride with and without a load. I tried the jounce style overdrive rubber blocks and they rode very hard when the truck was loaded. The RAS springs were installed in about 20 minutes per side. I made a 1.5mm gap and they work great. I am currently towing my 5th wheel on a 12,000 mile car trip. These progressive springs offer a…

It's not often that I come across a product that advertises easy installation and actually delivers on it. It took me longer to remove the wheels and jack up the rear leaf springs than it did installing them. The instructions that came with it were great! I installed them on a 2013 Ford F150 and they fit perfectly even though they only say 2012. The adjustment was easy and you have two spacers available, although you can use a dime for 10% and a quarter for 40%. Just a note for future buyers…

Very easy to install. Thanks to the accurate design and testing of the product, everything worked as advertised. I set mine to 40% (2mm black washer) on a 2017 F-150 RWD and raised the rear end about an inch. Ride quality is excellent and there is no noise from the unit itself. However, at the 2mm setting, there is a significant increase in stiffness and you will hear noise propagating through the frame/platform when hitting sharp bumps in the road meet street. This was my experience with a…

Used at a great price. Installed on F150 2017. The main reason I wanted these airbags is to match the springs without changing the fender liners on my beefy rear wheels. Was a bit frustrated because the truck lifted 3/4" at the 25% setting. I notice smoother shifts just when driving the truck. No squeaks or background noise. Bed full this 4th of July weekend Carry firewood about 200 miles. Will update handling and ride when I do. Hope this helps. If you are a casual carrier, choose this setting
