When you hitch up a trailer or load the bed, the rear suspension can sag and throw off your handling. The RoadActive Suspension Custom Leaf Spring Enhancement Kit adds up to 2,000 lbs of support by turning your factory leaf springs into a mechanically active system. It automatically adjusts tension to the load, keeping your ride level whether you’re towing, hauling gear, or carrying tools in back. You get steadier steering, better braking traction, and correct headlight aim no matter the weight behind you.

Heavy loads can make your truck lean or bounce through turns and cause wheel hop when accelerating. The variable-rated coil tension springs in this kit engage instantly to stabilize the leaf springs before problems start. They strengthen your suspension to cut down sway and body roll on corners while preventing axle wrap and bottoming out under weight. The result is a smoother, more controlled ride with improved traction during braking and acceleration.


Unlike systems that need constant pressure checks or air adjustments, this setup is ready to go after installation. Each unit bolts under the factory leaf spring and around the U-bolts—no drilling, cutting, or welding required. Once tensioned during setup, the springs activate automatically when loaded and disengage when empty. There’s no need for regular monitoring or maintenance, just reliable performance every time you tow or haul.


Long days on the road mean exposure to rain, salt, and grit that can wear out lesser parts. Each RAS unit is made from high-grade alloy steel with an epoxy e-coat for corrosion resistance. The end brackets have a salt spray rating of more than 800 hours, giving them lasting protection against rust and harsh weather. You get a suspension upgrade that holds up to years of heavy use with confidence backed by a 5-year warranty and 30-day money-back guarantee.

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.

When I installed it I set it up for 25 load and I pull a 9000 lb dry weight 5th wheel. The suspension kit is still doing its job.

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?
