Heavy trailers or fully loaded beds can flatten your stock springs and make the back end sag. The RoadActive Suspension Custom Leaf Spring Enhancement Kit adds up to 2,000 lbs of support by turning your passive leaf springs into a mechanically active system. The variable-rated coil tension springs instantly absorb and support the extra weight, keeping your ride level and steady for better traction, braking, and control when towing or hauling.
When curves, crosswinds, or passing trucks try to push you around, this kit keeps the rear end planted. The built-in coil tension springs stabilize your load to reduce sway and body roll before they even start. That means smoother cornering, less rocking through windy stretches, and more confident handling with a trailer or camper behind you.
Under heavy load, leaf springs can twist or flatten, causing axle wrap and wheel hop that throw off traction. The RAS system absorbs those twisting forces to keep the springs in position. That eliminates wheel hop and bottoming out so your tires stay connected to the road. It also cuts down on wear to shocks, shackles, and tires by keeping the suspension working as it should.
No air lines, no compressors, no constant adjustments. This custom kit comes fully assembled and bolts directly under the leaf spring using factory U-bolts—no drilling, cutting, or welding required. Once installed, it automatically adjusts to your load without the need for monitoring or maintenance. Durable epoxy e-coated steel construction and corrosion-resistant brackets with an 800-hour salt spray rating mean it’s built to handle real-world work for years to come.

Jeff: Hello, everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit. This is a custom-fit part. It is designed to fit the 1999 Chevrolet Tahoe and GMC Yukon vehicles, and on a custom-fit part like this, I always like to recommend for you to go to the website, use our fit guide, put in your year and model vehicle, and it'll show you if this'll work for your application.Now, this custom kit will convert your vehicle's factory leaf springs into a mechanically active suspension system. It will actively strengthen the leaf springs for improved ride quality with or without a load.
And it is a nice all-in-one suspension system, improves stability, handling and control. It will help eliminate axle wrap, wheel hop and bottoming out. Reduces dangerous sway and body roll when you're cornering, and it will also help keep your ride level when you're towing or hauling a heavy load. Improves the traction while you're breaking and accelerating.Does use the variable rated coil tension springs, which automatically adjust to your vehicle's load. They do activate immediately to support the extra weight, but they'll disengage when it's unloaded, allowing your leaf springs to perform as intended.
They are customizable coil springs that can be adjusted during the installation to accommodate your towing or hauling needs. And they are independently adjustable for side-to-side leveling of any off-center loads.This kit will help extend the life of your leaf springs, your shock absorber, shackles, and even your tires. They are a nice durable epoxy e-coated steel construction. The corrosion-resistant brackets on the ends of each unit have a salt spray rating of more than 800 hours. And it is an easy bolt-on installation.
There's no drilling, cutting or welding required. Basically the unit secures under the leaf spring and around the factory U bolts.It is a fully assembled kit. When you order it, it'll come just like this, all put together. All the hardware is also included. It is maintenance-free.
The adjustments and the monitoring are needed once it's installed, and then after that, it . not needed anymore. These parts are made in the USA.A few specs on this. The weight capacity is 2,000 pounds. Now just a note, the Roadmaster active suspension will not increase your vehicle's weight carrying capacity. But that should do it for the review on the Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit.

Well It has not failed me yet. Being basically a spring under load all the time I am assuming the spring will stretch some over time and I will have to adjust tension accordingly. The pickup sits nicely on the thinner washer setting so I am leaving it there and hopefully that will help the system last longer.

Looks great, Les :) I hear lots of good this about this option for suspension enhancement and how you said, even without towing it can improve the ride quality. Glad to know that you are happy with them, too! do you have any upcoming camping trips planned?

What can I say. After a year of constantly driving through Texas roads and highways. I have moved twice and loaded the bed of my truck plus U-Haul 6x12 trailer and thy truck has not felt the load of it. The Active Road Suspension Leaf Spring is constantly sort of speak sensing if theres load so it can actively push it upwards. I have even driven up to the crazy roads of Pennsylvania and my pick drives smoother than when I got it from the dealer. Im telling you these things work. As any cautious driver upkeeping his own vehicle, I have periodically checked the bolts and location of the resistance in between the spring and it has not deflected or moved from its original installation. I believe every pick up must have these. It beats constantly putting air on the air bags especially in inclement weather like up here in Pennsylvania with the snow. I couldnt be more satisfied with this purchase. Thank you etrailer for offering this superb product.

After a year I am still pleased with this product. I had been adjusting the spring tension higher when towing and then back down after a trailering trip, but now just leave it adjusted to the trailer towing tension as the unloaded ride doesnt seem to suffer when the springs are tighter.

OMG!! I have done extensive traveling with my trailer over the last year and the RAS system has made a huge difference in sway, road buffeting and squat. I can’t imagine not having this on any vehicle that tows!
