Complete Front + Rear Suspension Upgrade Packages
What Makes Combo Kits Stand Out
How It Works
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.
Built to Withstand the Toughest Environments
Engineered for Demanding Duty
Durability That Outlasts the Road Aheadvironments
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
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.
Why the Industry Trusts SuperSprings
Backed by Experts, Proven in the Field
