Comment ça marche

Self-Adjusting Support That Adapts in Real Time

Combo Kits use SuperSprings® helper springs and matched front support upgrades to automatically respond to weight changes. As your vehicle takes on load, the system progressively engages—leveling your stance and stabilizing your ride. When unloaded, it returns to neutral for a factory-like feel with no manual input required.

This means whether you’re towing a trailer, carrying tools, or overlanding with gear, your suspension adapts instantly for comfort and confidence.

Conçu pour résister aux environnements les plus difficiles

Engineered for Demanding Duty

Durability That Outlasts the Road Aheadvironments
Combo Kits are made from high-grade, shot-peened steel and high-density materials designed for years of punishing use. Whether you’re facing harsh job sites, off-road trails, or long highway hauls, they thrive without requiring maintenance.

With no moving parts, air lines, or compressors, Combo Kits are a true “install and forget” solution—quiet, dependable, and built to last.

Smarter Suspension Support, Without the Tradeoffs

Why Combo Kits Beat Add-A-Leaf and Airbag Systems

Add-a-leaf kits and airbag systems often come with compromises—stiffer rides, complicated installs, and ongoing maintenance. They can reduce flexibility, require adjustments, or even risk OEM warranty coverage.

Combo Kits solve these problems by staying passive until needed, then progressively engaging for support. With no air lines to leak and no disassembly required, you get a smooth ride when empty and the extra support you need when loaded—all in one package.
