During the development of Old Man Emu’s Nitrocharger Sport shock absorbers, Ride Control Engineers tailor shock absorber valving to work with the different springs in the range, often resulting in multiple shock absorber options for each vehicle. Old Man Emu Nitrocharger Sport is a twin-tube design with the outer reserve tube protecting the internal components off-road. Utilizing the latest advances in shock absorber technology, Nitrocharger Sport is the most finely tuned 4×4 shock absorber on the market.
