- Performance enthusiasts
- Light and heavily loaded trucks and SUVs
- Daily driven trucks and SUVs
Features:
2.5” Monotube Aircraft-Grade Aluminum Construction: The 2.5” extruded monotube body is made from 6061-T6 aircraft-grade lightweight aluminum, offering up to 4x better heat dissipation and 30% weight saving than steel for enhanced durability and cooling efficiency.
Large 57mm Billet Aluminum Piston: The CNC-machined billet aluminum piston offers 60% more surface area than traditional designs, enabling precise valve tuning for exceptional ride comfort and control.
Premium Build Materials: High-pressure (200PSI) nitrogen gas, NOK seals, and Fuchs hydraulic oil contribute to long-lasting durability and high performance under extreme conditions.
Velocity-Sensitive Design: The monotube damper adjusts seamlessly to changing terrain, providing a plush, smooth ride on highways and responsiveness on rugged trails.
Type 2 Anodized Corrosion Resistant Finish: Military grade anodized corrosion-resistant finish withstands harsh weather, mud, and road grime for extended durability and reliability.
Double-Bonded Natural Rubber Bushings: Built with double-bonded natural rubber bushings for superior durability and resistance to weather and environmental elements, offering hassle-free performance and reliability.
Adjustable Coilover System: Equipped with an Acme-threaded body, the IM2.5 allows for infinite tuning of the ride height to suit different loads and driving scenarios.
Covered for the Unexpected: Backed by IRONMAN 4X4’s 4-year unlimited-mileage warranty, —unlikely to be needed thanks to the IM2.5’s legendary durability, but there just in case the unexpected finds you.
Unmatched Durability and Longevity: The IM2.5 Monotube Suspension is engineered for unmatched durability and longevity, eliminating the need for regular servicing required by comparable shocks, thanks to its advanced design and premium materials—though fully rebuildable, it's built to perform flawlessly without maintenance.
