Ironman 4x4 IM2.5 Shock - Toyota Hilux Revo 2016+ (73-057-081)

Short Product Summary

This Ironman 4x4 IM2.5 shock absorber (part 73-057-081) is specified for the Toyota Hilux Revo 2016+. Its 2.5-inch aluminium monotube body, internal floating piston and vehicle-specific tuning are aimed at all-day comfort.

Why This Product

Heat is a big problem for shock absorbers on long, rough tracks, and aluminium manages it better than steel. The IM2.5 uses an extruded aluminium monotube body and a large 57mm piston that allows fine valving, aimed at a smooth, plush ride from suburban roads to rocky high-country tracks. On a Toyota Hilux Revo, the part number matters, because each shock is tuned for its own vehicle.

Key Features

• Aluminium monotube body – extruded aluminium handles heat better than steel, which helps the shock keep its composure
• Type 2 hard anodised finish – a tough exterior finish to handle an off-road beating
• 57mm CNC billet piston – low-speed bleed ports give a smooth, plush ride from town streets to rocky tracks
• 20mm hardened steel rod – protected by a robust dirt shield and NOK seals
• Internal floating piston – an inline design with 200PSI nitrogen gas instead of a remote reservoir
• Upside-down mounting – the 3-4mm thick body sits out of harm's way from stones and knocks
• Vehicle-specific tuning – each shock is tuned for the vehicle it is made for

Ideal For

• Toyota Hilux Revo owners who want a replacement that is matched to their vehicle.
• Off-road tourers wanting all-day comfort on long trips.
• Drivers wanting a tough finish who want a shock protected against stone knocks.
