INEOS Torture Testing in Moab

Springs – Designed with Eibach

We partnered with our friends at Eibach Suspension (the OEM spring supplier for the Grenadier) to develop custom 4" lift springs. The goal? A spring that excels off-road while maintaining impressive on-road comfort and handling. Mission accomplished—we love the final result.

Shocks – Tuned by a Legend

Our shocks are custom-tuned for Owl by Dan Fresh, winner of the Baja 1000 and King of the Hammers. You can drive confidently knowing one of the world’s top off-road racers helped dial in this system.

We took Dan, our tech team, and our rigs to the holy land of off-roading: Moab, Utah. There, we created a test loop combining pavement, washboard, and technical rock crawling to fine-tune the shocks across every terrain. After days of testing and dialing in, we came away with performance that outclasses anything we’ve tested before.

Key Features

10" of Down-Travel

Down travel refers to how far a wheel can drop below the chassis when the suspension extends. While lift kits often focus on raising a vehicle, it’s increased down travel that truly unlocks off-road performance.

Improved Ride Quality

Extended down travel gives the suspension more range to absorb dips and drop-offs, reducing the harsh jolts you’d normally feel. This results in a smoother, more composed ride—even on rough trails.

More Suspension Articulation

Added down travel increases overall articulation (how much each wheel can move independently). This helps keep your van stable and balanced, even when crossing obstacles or off-camber terrain.

Reduces Bottoming Out

By increasing travel in both directions (up and down), your suspension system has more room to work, reducing the chance of bottoming out or hitting bump stops too early.

Greater Control at Higher Speeds

With more down travel, your tires can track the terrain more effectively, especially at speed. That means less bouncing, better control, and more confidence when driving fast over variable surfaces like washboard or whoops.
