Foam Cell Pro

Suspension Built To Last

Our Foam Cell Pro shock absorbers feature a tough, military spec, big bore 3" twin-tube shock, the largest, strongest shock on the market; they are nearly indestructible, carry no internal parts which can jam, require little to no service, and are rebuildable.

Foam Cell Technology

Foam cell technology replaces traditional nitrogen charging with a closed-cell foam structure that physically separates oil from nitrogen, preventing aeration and maintaining consistent damping performance.

Twin-Tube Design

A twin-tube shock design with Foam Cell Pro technology offers superior heat dissipation and durability, making it ideal for heavy-duty off-road and overland applications. The foam cell insert reduces aeration and shock fade, ensuring consistent performance and control in extreme conditions.

Premium Grade FUCHS Oil

Featuring the highest grade German oil that resists viscosity breakdown under high temperatures.

Adjustable Coilover System

Equipped with a threaded body, Foam Cell Pro allows for infinite tuning of the ride height to suit different loads and driving scenarios.

Completely Rebuildable

Foam cell shocks are designed to be rebuildable, allowing for easy maintenance and extended lifespan. This ensures you can restore peak performance for a better long-term investment for off-road adventures.

Oversized Natural Rubber Bushings

Built with oversized natural rubber bushings for superior durability and performance under extreme conditions and high-frequency vibrations.

Robust Dirt Shield

The shock absorber features a replaceable dirt and stone shield guarding the hardened piston rod and seals against debris and damage.

Covered for the Unexpected

Backed by IRONMAN 4X4’s 4-year unlimited-mileage warranty, —unlikely to be needed thanks to the Foam Cell Pro’s legendary durability, but there just in case the unexpected finds you.
