    • Easy install,
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! ... show more

    • Game changer
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. ... show more

    • Easy to install
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!! ... show more

    • Installation
Review Image by MS MS
Super easy installation on my ‘23 F150. After finding the tools I needed and installing the drivers side (about 30 minutes), I literally had the passenger side installed in a little more than 5 minutes. I set the coil to 25% and the truck drives fine after installation with little to no ride change. Anxious to hook up to the RV and test for real seat of the pants towing improvements. ... show more

    • RDS suspension
Installation was a breeze. Hauling 10k with an F150 can be sketchy, RDS sucks up the weigh and the truck hauls the weight and stays level without losing gas mileage

    • Amazing upgrade. Improved handling.

Installation took me a little while longer as I’m a little slow and new to working on vehicles. After my swollen lug nuts were finally removed, I then removed my tires (had new lug nut ready). The fit was perfect, used the second hole. Truck seems a little quieter too. The handling seems better and I’m testing if there is a difference in speed too. I set the spring to the suggested max load. Truly a great quality and value for my money. One issue. When tightening the spring on the last side of the install, the male allen head came unglued from the allen female part. I was able to tap it back in to finish the install. But I’ll keep the allen head so it won’t fall out on the road. ... show more

    • Works great!
My 2022 f150 tremor had major sag with my trailer. This completely eliminated it! Is used the black space and might actually need to back it off a bit. It does make it a better ride and decreases the float over bumps. It does lift the rear over an inch and a half but fine by me. Also caused some squeek that I am still trying to pin point but again, completely changed the ride for the better! ... show more
