2,000-lb Capacity. Convert your vehicle's leaf springs into a mechanically active suspension system. RAS adjusts to your load to level your ride. The system also increases stability, handling, and control by improving traction and reducing sway.I installed the Road Active suspension standard duty kit on my 2017 Tundra. I was hoping for a smoother ride with and without a load and I was not disappointed. I don’t do heavy hauling, just a center console boat that weighs about 3000 pounds with trailer. My truck definitely has a smoother ride. It is especially noticeable on rough spots like bridge crossings, etc. I set the springs somewhere in between the light and heavy settings. I used a quarter as a spacer. It raised the rear of my truck one inch. I definitely recommend the Road Active suspension and etrailer is the best place to buy it.
Just installed,took about 3 hours. My 2015 tundra would drop 5" when I lowered the trailer, now it only drops 3" and sits level. Did a 15 minute test drive, I felt like the ride over bumps and dips was improved. The only complaint is the installation instructions were very poor.
Very easy to install and make a big difference towing a trailer!
I really like the installation process and the results where good but I do wish I went with the heavier model
Pretty easy install on my 2012 Toyota Tundra. I pull a 25’ airstream front BR travel trailer. It’s got at least a 1,000 # tongue weight. I was sagging in the rear, and getting a lot of porpoising when on concrete sectioned roads. The RAS eliminated the sag, and greatly reduced any porpoising. The truck seems way more planted with the airstream in tow. I’ve even moved it around a bit without the weight distribution bars in place. Truck is level now when towing. I know this doesn’t actually change the payload rating for the Tundra, but it sure changes how it pulls my trailer and hauls heavy loads. I also went to E rated tires.
I really like the suspension add on. It keeps my truck level when towing our 9000 lb camper bumper pull. I get great stability on the road and it helps with handling the tongue weight on my 2013 Toyota Tundra 1/2 ton. It doesn't change the stiffen the suspension of my truck until I add weight. So, you don't notice it with normal driving. Installation went smoothly. The components were high quality and heavy duty. I recommend it.
Mounted on 2015 Tundra ,pull heavy car trailer and toy box these work great and are adjustable. Unlike airbags they won't leak and much easier install. They helped level truck when I'm loaded and resolved some front braking issues with the sensors on these new vehicled.
Overall, I'm super pleased with both the product and services from etrailer and the suspension enhancement seems to work well for my application. Small camping trailer, helped take away most of the sag.
When I began the installation I set up the Tundra on my slopping driveway with chocks and attempted to jack it up with my small floor jack. Once I saw that I had to remove the spring eye plate I decided it was not very safe. I ended up going to my son-in-laws where he had a floor lift. After lifting the truck it was a very easy installation. I did watch U-tube about 6 or 8 times to make sure of the adjustments and as I said it went very well. Here are a couple of photos.
We added these to my 2017 Tundra which we use to pull a gooseneck horse trailer. We camp on USFS lands and roads can be bumpy, rutted, etc. this stiffens up the suspension and we’ve never had any issues with bottoming out.
I bought this kit for my 2019 trd pro it’s an absolute must for the saggy leaf springs in the tundra especially the fox shocks but these give it a way better stance on the back with a 3” lift kit. you can tell this difference as soon as you drive the truck ABSOLUTELY FANTASTIC!!!!
Shipped fast and the box had easy instructions. Definitely a DIY-capable project, and worth the purchase! -2018 Tundra 4x4
So easy to purchase w - Jessica/ Parts came across US just in time.
2nd X buying these, so will see HOW they fit in a couple of weeks.
THX & God bless..PRAYING for safety of all concerned with virus.
I am a competitive shooter and take my camper to all my shoots. I have a cap on my truck and the decked drawer system. I also carry 400 lbs of ammo at any given time. When pulling my camper on the highway or over bumps and railroad tracks it was kinda scary. This system stopped the squat and removed the sag at acceleration. I installed sumo springs as well (without spacer) for added sway control when loaded down with trailer. The RAS was great right from the start. It reminded me of the 80’s then we would put traction bars on old hot rods to stop rear squat on acceleration. Same kind of feel with my truck. Some much nicer. With the trailer it removed 1.5 inches of squat on the rear and got my front and back within 1” of variance and before install it was around 2.5 to 3. Took only fifteen minutes per side to install once the tires were off. Great product….
Received these ahead of schedule and all intact. I watched the video on etrailer.com and youtube, very helpful.
The installation is not difficult if you are handy with tools. Aside from it deciding to rain on me during install it was not bad. Suggest you lay out all your tools and include a couple of adjustable wrenches. First off, unscrew that gold screw alot, when you think there is enough, go more, the first side I was short. I wiped down the truck springs to remove any dirt there and set up then tightened by hand, you can't go far that way but gets you started. On the rod with the 2 nuts that will lock together when done, I gave myself about 3" of thread and locked them together to hold the threaded rod while adjusting, no way to hold the end nut, this worked out well. The one thing I would have done different is the adjusting nut is 14mm, I only have a 6" ratcheting 14mm, doable but at the end it tough, I wish I had a 10" or so, there was space in my install. I set mine to high since I pull a 5th wheel so adjusting was the hard part.
I will not know until spring if this helps with the towing as the camper is now stored but very hopeful from others input. If anything changes I will update.
I bought these after a 1000+ mile trip towing my trailer (~8000# loaded) with my 2013 F-150 (HD Payload & Max Towing Package). Installation was super easy. I did not need to take the tires off. There was plenty of room to get behind the tires and place and adjust the springs. Once installed they definitely give the truck a rake. I didn't measure pre-installation because I didn't expect the lift to be so great. I used the black disc to adjust the springs.
It's not too extreme but you can definitely see a difference compared to stock.
As you can see in the pictures, with the springs the drop with a trailer attached is greatly reduced and the truck sits level. Towing was great. I used a WDH before and being able to with springs only and a sway bar is pretty nice. Drop with trailer attached is only about 2.5 inches (see pics)
Straight-forward installation on a 2007 Pleasure way Excel RV (I did it myself in a few hours) although I did have to modify the air bag mounting bracket with a slot to allow RAS hardware to fit. Great installation instructions. Vehicle height is now correct and could be made level by tension adjustment during install. Handing is improved, I was able to remove aftermarket sway bar which improved ride. I have been considering installation of stiffer rear shocks to soften rebound now that the rear spring rate is increased.
I received this kit in a very timely manner always do from etrailer have some issues with the instructions that come from roadmaster not a trailer the bump stop spacer didn’t say that you need to use the original bolt from the bump stop so it slowed me down greatly on the install however I took it out on a quick run without a load I do feel that this has made the unloaded ride smoother tomorrow I’ll be taking the trailer out for a bit and we’ll see how it works there and I’ll update this rating.
Admitedly, I haven't even rolled my '07 Silverado 2500HD classic out of the garage yet, but I'm already very pleased. I had to go to a neighbor for a 10mm hex key socket and was slowed down by my 7yo kid 'helping', but it was still only 90 minutes my jack stands were in use. Easiest thing to do!
My only small downsides so far:
* needed to find a 10mm hex key that I apparently don't own, not sure why they picked that fastener
* wish I put some loc-tite on; just to make me feel better
* distance to drop the axle so the suspension fully hangs was way further than I expected; barely had my jack stands tall enough to get the job done.
These aren't really bad on the product, just notes for future customers. We're towing the 5er about an hour an a half this coming week, hopefully it steadies up a lot!
Sure beats air bags or blocks! My Gmc canyon diesel is a great puller, needed help with suspension hauling load limit. Easy to install and works great. On high setting it raised the truck rear an inch or two even empty but the way gmc set up the suspension I consider it a good thing.With my tandem axle 16' trailer loaded it's a saving grace.

I still wish I went with the heavier modal. But overall it’s a very good product. I just needed a heavier duty version.
