Ironman 4x4 72-057-744 Shock Absorber

The IM2.5, a 2-1/2 inch extruded aluminum monotube shock absorber, has been tuned for ultimate ride comfort while leveraging class-leading materials and design elements to offer a robust and versatile on and off-road suspension solution. Featuring a 57 Millimeter CNC billet aluminum piston, the shock absorber takes advantage of the maximized internal capacity for optimal fine-tuning. The large-diameter piston features low-speed bleed ports which ensure a smooth and plush ride both on urban and metro roads through to rock crawling high-country tracks. The IM2.5 is tuned perfectly for those who truly value all-day comfort in their 4x4 suspension solution. Designing an aluminum monotube shock absorber is beyond having a shock that delivers on the cool factor. Internal heat is a shock absorber’s kryptonite. Aluminum is proven to be up to 4x more efficient in managing heat than steel, which makes it the optimal material for heat dissipation in a shock absorber. Additionally, the monotube design optimized the cooling efficiency further by offering a greater surface area and respectively greater direct cooling to the internal hydraulic fluids. The IM2.5 is no city slicker. The monotube aluminum body is Type 2 hard anodized to ensure a robust finish to handle an off-road beating. Further the 3-4 Millimeter thick walls are cleverly mounted upside down to keep them further out of harm’s way, with a robust dirt shield is utilized on all rear shock absorbers to further help protect the 20 Millimeter hardened steel rod and renowned NOK seals of the IM2.5 monotube shock absorber. The IM2.5 was designed with comfort and robustness in mind and while the temptation was there for a remote reservoir, the inline design of a billet aluminum internal floating piston matched with high-pressure (200 PSI) nitrogen gas offers an unmatched simplicity and robustness for off-road tourers.
