The Ironman 4×4 Foam Cell Pro ‘A’ Lift Kit is the ultimate Outback solution.  This kit is matched with ‘A’ (light) springs. This military-grade, oversized, steel, twin-wall shock absorber is practically bulletproof.  Featuring foam cell technology and providing improved control for heavy loads, the Foam Cell Pro range is simply Bigger, Bolder, and Better!

Aluminium is lighter than steel; in fact, the IM2.5 offers a 30% weight reduction over a twin-tube steel shock absorber.

Additionally, the use of aircraft-grade 6061-T6 Aluminium in the IM2.5 offers improved cooling, which in turn means a shock absorber which can run harder, for longer, without diminishing its performance. Aluminium is known for its improved heat management, and has 4 times the thermal conductivity of steel.

The IM2.5 Monotube suspension series features a CNC ported billet aluminium piston with an O-Ring sealed PTFE-Teflon band. The precision channeling allows for ultimate tuning to soften the smallest of bumps in the road.

The billet aluminium Internal Floating Piston (IFP) features class-leading NOK seals and separates the high-pressure 200PSI nitrogen gas from the Fuchs hydraulic oil.

With a wall thickness ranging 3-4mm across the range, the IM2.5 monotube shock absorber tube is finished with ultra thick and durable Type 2 anodizing, for ultimate protection. The monotube tech has also allowed us to mount the shock absorbers ‘upside down’ keeping the monotube body mounted high away from rocks and debris, and the 20mm hardened steel piston rod is downward yet protected by a robust dirt shield.
