Dobinsons 1.75″ IMS Suspension Kit for 2023+ INEOS Grenadier

The INEOS Grenadier was engineered from the ground up for proper off-road abuse, but the factory suspension can sag quickly once you start bolting on a heavy winch, recovery gear, and a roof tent. The Dobinsons 1.75" IMS Lift Kit solves this by properly matching your spring rates to your payload while replacing the stock twin-tubes with massive 2.6-inch monotube shocks. This system gives you the clearance needed for larger tires, restores critical bump travel, and is tuned to dissipate heat across endless miles of washboard on Forest Service Roads.

Key Features

• 2.6" Monotube Shock Bodies: Large 66mm shock bodies drastically increase oil capacity and resist cavitation, ensuring consistent, fade-free damping over sustained rough terrain.
• Precision Load Tuning: With multiple spring rate options, you can dial in the suspension geometry based on your exact build weight. Keeping the chassis balanced and predictable whether unloaded or carrying a full camp setup.
• High-Pressure Nitrogen Gas: Delivers rapid valving response, forcing the tires down to maintain traction through deep ruts and cross-ditches.
• Trail-Tested Internals: Built with NOK long-life seals and custom-blended FUCHS oil to handle extreme thermal loads and heavy compression forces without blowing a seal deep in the backcountry.

Pro Tip: Coming from years of building solid-axle rigs like the 80-Series Land Cruiser, we know how critical it is to get your spring rates right. Don't buy springs for the weight you might add in two years. Buy for the steel and gear bolted to the truck right now. Over-springing a light rig ruins the ride quality.
