Old Man Emu takes its name from the bird that glides over rough ground at full speed without breaking stride, which is exactly what this suspension has done for 4x4s since 1976. Owned by Australian off-road giant ARB since 1988, OME engineers do something few suspension makers bother with: they tune every Nitrocharger, Nitrocharger Plus, and BP-51 bypass shock to a matched spring selection for each specific vehicle, load, and accessory setup, tested on shock dynos and in the brutal Australian outback. The result is the suspension that overlanders trust under loaded Tacomas, 4Runners, Land Cruisers, Jeeps, and Defenders around the world, delivering ride quality and load control that make rough country feel like a well-worn track.
