**Q: How much does RAS increase payload capacity?**

**Q: How is RAS different from other suspension helpers such as air bags?**
A: RAS offers a  more complete solution,  where enhancing stability, reducing rear squat, dampening excessive rebound, improving performance, and providing same-as or better-than-stock ride is just as important as reducing rear squat.

## Customer Reviews

### ⭐⭐⭐⭐⭐ A major difference on F150.
*by N***E on May 16, 2022*

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.

### ⭐⭐⭐⭐⭐ Worth its weight in gold!
*by W***9 on August 3, 2025*

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.

### ⭐⭐⭐⭐⭐ Works better than I thought it would.
*by K***D on March 24, 2025*

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!
