Hard to say just by looking at the pics, but they look like they are covered with oily muck from something that is leaking from the front of the truck that is blowing back onto them. Rear link and axle looks to have same stuff on it (oil w/road grime).Can I ask a question of you all since you know these components - my mechanic is telling me that both of my rear OME Nitrocharger Plus 63020 shocks are leaking / failed, after 5 months of on road use (purchased new in December).
Does that make any sense? I don’t know suspension at all, and am trying to figure out if the shop that installed them might have fouled them up, because both failing after on-road only use in five months doesn’t sound right.
I’m not looking for a diagnosis, just advice (go to manufacturer for defect, clean them and keep driving to see if they’re really leaking, etc.)
Thank you so much in advance

Highly unlikely. OME are very robust shocks. They are used all over world on trucks daily driven which never see tarmac, millions in use. If they were not built defective, there is very little that will blow them from tarmac use, excluding trauma from a crash. Hard to tell from photo if they are leaking or if dirt/oil is from some other source in the driveline. If your mechanic is >90% certain they have failed/blown have hime remove them and bench test them by manually compressing them and watch the rebound. If blown, compression will be easy and rebound will be very slow. If they are not blow then the reverse. Also, if blown, they should be covered by warranty if manufacturing failure. Good luckCan I ask a question of you all since you know these components - my mechanic is telling me that both of my rear OME Nitrocharger Plus 63020 shocks are leaking / failed, after 5 months of on road use (purchased new in December).

Very welcome. As ThatCableGuy also notes, just because there is grime/oil on the rear shocks that doesnt mean the oil is coming from within them. May I gusset you clean the outside surface of rear shocks with citrisolve or brake-Klean drive the truck and check for leaks in a few dozen miles? Also, have you done the rear end bounce check? Jump up and down on the rear bumper and fee/see how the shock compress and rebound.Thank you sincerely so much, this is so incredibly helpful.
Thank you! No, the vehicle was coated by the prior owner in a European version of Ziebart (asphalt-based undercoating, tar-like). The shocks are newer than that. I cleaned with brake cleaner yesterday to get a look this coming week at any changes.

Does the engine, trans, tcase have any leaks?
100%. I run King 2.5" remotes on one of my FZJ80s, Dobinson IMF on another and OME on yet another. The King, after you dial them in for your use, provide a significantly improved over the OME or Dobinson, but their price reflects it. BTW, I ran Aussie DMS for years on my rally cars, they are brilliant beasts!I'm probably a bit late to this discussion, but custom valved kings are in a different league to OME BP51s, which are better than the majority of other 'off the shelf' shocks.
IMHO
1) King
2) Fox/Icon etc
3) High end suspension manufacturers shocks; BP51, Dobinsons MRA etc.
