Keep Your Ride Level Under Load: Mega-Duty Rear Suspension Support

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 strengthens your factory leaf springs by up to 50% by turning your factory leaf springs into a mechanically active system. It automatically adjusts tension to the load, keeping your ride level whether youre 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.

Stop Sway, Sag, and Wheel Hop Before They Start: Variable-Rated Coil Tension Springs

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.

Set It Once and Forget It: Maintenance-Free Active Design

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-boltsno drilling, cutting, or welding required. Once tensioned during setup, the springs activate automatically when loaded and disengage when empty. Theres no need for regular monitoring or maintenance, just reliable performance every time you tow or haul.

Built to Handle Real-World Work: Epoxy E-Coated Steel Construction

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.
