When towing a trailer or hauling gear causes your rear end to sag, the RoadActive Suspension kit adds up to 2,000 lbs of support to your factory leaf springs. The variable-rated coil tension springs automatically adjust to your load, keeping your ride level and steady. That means no more squatting when you hook up a camper or load the bed, and your steering, braking, and headlight aim stay right where they should.
Heavy loads can twist leaf springs enough to cause axle wrap or wheel hop. The RAS system turns the passive leaf springs into a mechanically active suspension that absorbs and stabilizes those forces before they cause trouble. The result is a smoother launch and braking feel, better traction, and less wear on shocks, shackles, and tires.
When cornering or driving in crosswinds, weight shifting at the back can make your rig feel loose. The RAS system reinforces the factory leaf springs to control sway and body roll before it starts. Whether you’re towing a long trailer or carrying bed cargo, it keeps the rear planted so you stay in command through turns and highway gusts.
This kit comes fully assembled for an easy bolt-on install with no drilling, cutting, or welding required. Once tensioned during setup, the system needs no further adjustments or maintenance. The epoxy e-coated steel construction and corrosion-resistant brackets—with a salt spray rating of more than 800 hours—keep it performing reliably through seasons of towing and hauling.
During installation, you can adjust each coil spring between 25 percent and 40 percent tension using the included spacers. That lets you dial in the right support for your typical load or fine-tune side-to-side leveling if weight sits unevenly. Once set, the springs automatically engage under load and disengage when empty for a comfortable ride either way.

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?

That's a long trek, so I'm glad these helped you along the way! Do you take that trip often, Elden?

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.

Still working great. Towed a Flaggstaff microlite 23LB Travel trailer prob between 5 and 5500 LB’s to Niagra Falls with no problems, truck sat level with trailer and 2 adults,2kids. Getting ready to make a 2,000 mile round trip to disney in florida in a few weeks.
