@Farrell48 are both front shocks the same number?
48510-60591: is listed for these destinations LHD EU: (ARL,GCC,GEN,RUS,SA)
48510-60560: is listed for these regions, A, R, U (I would assume U is for United States?)
There are 5 different part numbers including two for a special package, looks to be NATO/Military/Industrial use type support requirements possibly?
I can definitely see shock valving being different based upon region being shipped to and quality of roads not to mention different engine configurations and therefore weight over the front end, wonder if Toyota ran out of stock and started substituting? The rears are all the same no matter destination unless configured for Egypt/Special package.
Based on this if it were me and the difference is that profound I'd ask Toyota to swap in the correct configuration parts or prove the valving is the same, taking it all the way to corporate/brand engagement if need be. May be a good idea to file a safety concern with NHTSA as well due the weight differences in engine configurations and possible valving differences will have an impact on handling and braking.
