## Description

Heavy Duty(HD) rear leaf spring upgrade by RoadActive Suspension designed to enable improved towing capability, comfort and everyday performance without hassle. Suspension kit comes as set of variable rated tension coil spring designed to strengthen existing leaf springs by an additional 40-50% over stock factory leaf springs. The mechanically active suspension works to maintain the arch in the existing leaf springs and engage proportionate to force or weight that is applied, absorbing and dissipating load force energy. The unique design helper spring provides greatly improved stability, increased & improved load carrying capabilities, reduction in rear squat, reduced bounce, improved traction and driver control. RoadActive Suspension guarantees 100% ride comfort and maximum performance, with or without load. Once installed with proper tension setting, no adjustments necessary. Heavy Duty kit ideal for most towing and hauling applications or with +2'' of squat while loaded.

Review: I didn't get a chance to try hauling my camper (28' Jayco) without these installed, so I can't truly compare them in that regard. But I can say that it did improve handling (less body roll in curves and corners, less wheel hop on wash boards) from the factory ride. Installed on 2023 Ford F-150 Tremor. I read multiple posts of people stating that a 28' camper is unmanageable with a half ton tow rig. I have not towed a huge amount, but I have towed with strong cross winds and poor pavement conditions (dips and varying grades) since installing this. My half ton handled everything well so far, and I believe the HD RAK system have made a huge difference to that. I have not experienced "porpoising" (front end of the truck bobbing up and down after going over a hump in the road) as many people with similar trucks have reported. NOTE. I do have a Husky Centerline sway and leveling tow hitch on my truck and trailer as well, and believe these 2 systems coupled together make all the difference in towing large campers with a half ton. I'm nowhere near my gross trailer weight rating (11,000 lbs) but I am near or at my payload capacity of 1640 lbs when trailer and family are loaded up.
Review: 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.

A: Beware of imitation kits sold online. Only genuine RoadActive Suspension products have been engineered, tested, and warrantied in North Carolina since 1998. Listings with RAS in the title are genuine RoadActive Suspension products.

**Q: How much does RAS increase payload capacity?**
A: While RAS  can strengthen the rear suspension by up to 50% in a progressive manner and can improve the way your truck handles loads; it and no other suspension upgrade can increase the manufacturer weight ratings.

**Q: Will RAS fit my lifted truck?**
A: From a fitment standpoint, RAS often fits lifted trucks without an issue.  Before ordering for your lifted truck, be sure to check your suspension for possible obstructions. If there appears to be an issue please contact RAS directly for assistance.

**Q: Will RAS help reduce my rear squat?**
A: Yes! While RAS is geared towards improving overall load handling, stability, and performance without hassle; RAS will also help reduce rear squat by up to 2-3 inches.

**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.

*by W***9 on 3 August 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.
