The aluminium advantage
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 that can run harder, for longer, without diminishing its performance. Aluminium is known for its improved heat management and has four times the thermal conductivity of steel.
Ultimate tuning
The IM2.5 Monotube suspension series features a CNC ported billet aluminium piston with an O-ring sealed PTFE Teflon band. The precision channelling 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 200 PSI nitrogen gas from the Fuchs hydraulic oil.
Built to last
With a wall thickness ranging from 3–4 mm across the range, the IM2.5 monotube shock absorber tube is finished with ultra-thick and durable Type 2 anodising for ultimate protection. The monotube technology has also allowed us to mount the shock absorbers upside down, keeping the monotube body mounted high and away from rocks and debris. The 20 mm hardened steel piston rod is positioned downward, yet protected by a robust dirt shield.
