Roadmaster Active Suspension 3611-YHD | Fits Ford F150 4WD

Easy install.Delivers as quoted.

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!

If you are here wondering if you should get it for your truck…do it! Absolute game changer. I didn’t take measurements before, but my F150 Supercrew was squatting significantly with my new 7550lb trailer. Afterwards, the squat was significantly reduced… which means handling way better by keeping front tires more on the ground, reduced sway, and able to drive faster (65mph). It raised the rear of my truck almost 2 inches but after the trailer is attached, my truck is perfectly level (3 inch squat overall). Driving without the trailer, the back is a little more stiff, but that comes down to drivers preference if you like it or not. I can tell it reduces the body roll, which I like. Install wasn’t too bad. Make sure you reference videos and paper manual because video fell short sometimes. But I would buy again. Now go ahead and add it your cart and buy.

J’ai installé le RSA sur mon F-150 2020 et le produit offre stabilité et confort. L’installation est exactement conforme au spécification publiée. Ce donne une note de 100%.

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.
