Isuzu Trooper and Bighorn chassis numbers

Isuzu identifies its four-wheel drives by a model code on the plate and the frame — UBS for the Trooper and Bighorn, KB and TF for the Faster and Rodeo, TFR and TFS for the four-wheel-drive pick-ups, RT50 and RG for the D-Max generations, UC and UE for the MU and Wizard — with the seventeen-digit VIN under JAA, JAB and JAC (Isuzu Japan), MPA and MP1 (Isuzu Thailand) and the badge-holder’s WMI on rebadged vehicles (6G1 and JA for Holden, JH4 for Acura).

The numbers are as the sources cited above record them — the parts trade's frame-number charts, the clubs' transcriptions of the makers' bulletins and the enthusiast decoders; a blank cell means no number is recorded. Registry research, not a factory record — check the vehicle's plate and the maker's build record before relying on a range. Corrections through the suggestion form.
