IM2.5 Premium Monotube Suspension System

Premium Ride Quality. Responsive Control. Built for Real-World Performance.

Upgrade your truck with the IRONMAN 4X4 IM2.5 Suspension System, a premium 2.5-inch monotube suspension engineered for drivers who want a refined ride on the street without giving up capability when the pavement ends.

Designed with a large 2.5-inch monotube shock body, high-pressure nitrogen, and vehicle-specific tuning, IM2.5 delivers responsive damping, improved stability, and confident control across highways, rough roads, and demanding off-road terrain.

Unlike suspension systems designed solely around lift height, IM2.5 is engineered around the overall driving experience — giving you a more controlled, composed, and responsive truck both on and off the road.
