Ironman Foam Cell provides the ultimate in 4×4 shock absorber design and features with 50% more oil for cooler running. Exceptional performance for both standard and raised height 4×4’s & superior ride control and comfort both on and off road is what you can expect from these shock absorbers.

The shocks, designed by Ironman 4×4 suspension engineers, have been individually made component by component to produce the world’s finest offroad shock absorber.

41mm Bore & Piston
Extra large oil capacity and massive piston surface area allow more oil than ever before and the abilty for Ironman to fine tune the valve performance with greater accuracy.
Perfectly matched to larger size vehicles where space permits.

18mm Piston Rod
Volumetrically matched to the 41mm bore and piston.
Maximum strength and rigidity for long stroke and high load applications.
Double chrome hardened for protection against damage.

Larger Oil Capacity
50% more oil than the Nitro Gas Shock Absorber.
More oil means more heat absorption resulting in longer lasting efficiancy.
High quality german Fuchs shock absorber fluid.

Foam Cell Technology
A gas impregnated sheet of Closed Cell Foam is positioned inside the shock absorber to replace the floating gas.
This separates the oil and gas, allowing full oil contact with the outer casing to radiate heat away from the shock absorber more effectively.

  • Exceptional performance for both standard and
    raised height 4×4’s
  • Superior ride control and comfort both on and
    off road
  • Improve stability when towing or carrying a load

Ironman Shock Absorbers
Each and every Ironman shock absorber is force
velocity tested before packaging to ensure all parts
received are uniform and within operating
specification. High quality materials such as German
Fuchs High temp shock absorber fluid, Japanese NOK
multilip seals are used. Strength and durability
requirements are sorted by the use of re-enforced
single piece eye rings and stems. Rubber shock
absorber bushes are used by Ironman, this is to
promote maximum flexibility and reduction in
unwanted side load and NVH (Noise Vibration
Harshness) transmission which often causes seal
failures in other brand shock absorbers using
