No, they’re asking about Old Man Emu, commonly abbreviated as OME. Confusing because of the similarity to OEM.I assume you mean OEM. OEM and typical aftermarket replacement dampers are incredibly crude and non-adjustable, so your best bet is to choose a damper that best matches what you need. I use my Xterra for a lot of towing and carrying motorcycles on a hitch carrier, so I choose HD dampers with extra rebound control, and they work well for my application. Rebound valving will be very different for damper intended for offroad use. Bilsteins seem to be a favorite of offroad enthusiasts. If you are mostly concerned about street driving, you could probably match the performance of the OEM dampers with KYB units, which would cost a lot less than what you would pay for Nissan parts.
