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.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.
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.
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
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.
Shipped fast and the box had easy instructions. Definitely a DIY-capable project, and worth the purchase! -2018 Tundra 4x4
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!!!!
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.
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.
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.

Really like this product. Was super easy to install and instructions were easy to read. Amy was very helpful in recommending the correct part and even took the order for me. Its winter here in the Rockies so I haven't had a chance to test out the load of my 5th wheel, but the ride still feels smooth. I have ordered from etrailer before and always have a good experience. Choose them with peace of mind.

Total transformation! I never knew how bad my ride was until I installed these RoadMaster 3611-HD active suspension. It took longer to safely jack my truck up and remove tires than it was to install them! Absolutely a game changer. I carry about 1000 lbs of tools and supplies daily and like riding a Rollercoaster when hitting bumps. Now, i hit bumps on purpose just to feel these RoadMasters work their magic! Love them!

A year later and they still work great! It’s impressive how improved the handling in our 2013 Ford F-150 FX4 even without our 30ft camper on the back. No more spinning shale going up our driveway or sway on highway, these give it a much more planted stance in all applications. Hauling our camper without a major squat or hitting the bump pads is achievable with these units! You will not regret this purchase! I installed them on my own, in my garage along with new Bilstine shocks I purchased online in less than an hour! Great instructional YouTube videos showing proper install. Not a mechanic at all, I work in Sales for ADT Security and drive over 4,000 miles a month.

If you're buying kit 2611 for a Magnaride Denali or other vehicle using that setup, you should know this version doesn't include a bracket to go around the U bolts. You MUST drop the axle, remove the spacer block between the leafs and the axle, remove the U bolt locator plate, and sandwich the forward bracket of the RAS between the locator plate and the top leaf. You have to drop the axle because there is no way to remove the locator plate retention bolt from above (if you just turn the nut, that bolt, which serves as the centering pin, just spins in place). If I knew this before I ordered, I might not have ordered this kit. It took me a lot longer than expected to install as it was my first time dropping my rear axle away from my leaf springs. It's not a hard job, just not for the faint of heart if it's your first time. So here's the procedure for a Denali Magnaride. 1. Jack up rear of truck and put jack stands under the forward leaf spring mount points. 2. Working on one side only, place a jack under the axle on that side and remove the lower shock mounting bolt. 3. Remove the Magnaride actuator from the upper Magnaride sensor lever. 4. Remove the U bolts. 5. Lower the jack to guide the axle away from the leafs. 6. Pull out the spacer block and the Magnaride lower actuator plate. 7. Put clamps on the leaf in front of and behind the U bolt locator plate. 8. Grab the bottom of the pin/bolt with a vise grips or channel locks. It's not a bolt you can put a wrench on. 9. Remove the locator plate nut. 10. Put the lower RAS bracket over the pin/bolt and place the locator plate on top of it. 11. Reassemble and torque everything to spec. BE SURE TO DO ONE SIDE AT A TIME to ensure you don't screw up your pinion angle or anything like that.
As for how it works, seems great after first drive. Will be towing with it in a couple days (boat with about 350 lb tongue weight) but I like how it tidied up the back end, which felt a bit floaty without this kit.

I have a 2020 Silverado 1500 6 cyl Duramax with the Diesel Off Road package (3.73 diff). Travel trailer loaded is probably about 6,000 lb. I took several measurements during and after the spring kit installation. All measurements increased about an inch including the stock suspension with trailer and equalizer bars and with the spring kit installed at 1 mm spacing. A one inch improvement overall. I took the truck on a short drive and didn't notice any difference in ride (wasn't stiffer) which is what I wanted. Good to know that I can adjust the springs to the 2 mm spacing if I want to increase the suspension assist. Going camping next week and looking forward to see how it improves handling and porpoising.

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!

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.
Review from a similar RAS in Vehicle Suspension
Overall, very happy with the product. GMC didn't have any way to improve the truck from squatting when I hooked up my trailer. This kit didn't stop the squatting but significantly reduced the bounce on bad dips in roads, bridge/road transitions and bad railroad crossings.
Review from a similar RAS in Vehicle Suspension
Good service. Fast shipping an very easy installation. Can tell alittle difference already. Haven't hooked up to anything yet but always have a good bit in the bed 85 gallons of diesel an 2 full toolboxes
Review from a similar RAS in Vehicle Suspension
Not to happy with the RoadActive suspension leaf spring kit. I loaded them on a 2017 f-150 with a 6” lift to pull a 6000lbs bumper pull trailer. Still squats pretty good even with the RAS torque to the highest/Safest tension and also quite a bit of bounce in it. I do have a weight safe brand adjustable ball hitch to try to counter the Small height from the lift. I do like the look of it on but don’t feel to safe towing the trailer
Jenny N - 10/27/2022Review from a similar RAS in Vehicle Suspension
Roadmaster active suspension seems to be built very well. I look forward to towing my travel trailer very soon to see if it improves the towing experience.
