About 4-5 months ago I fitted a chinese air locker from JamesW on this site to my 88 bighorn - this club truck has a 4" lift and runs 33s. Have since done about 12 tracks, time enough to give this locker option a good workout over some tough terrain and to run it continually for periods of time.
I am pleased to say the air locker has performed extremely well and has never missed a beat in this time. Has been 100% reliable - switch it on, switch it off and it works perfectly, delivering major traction increase. Have previously run aussie lokkas and I like them - but the low price and good performance of the chinese air locker gives now another sound selectable locking option for club trucks.
James, so far as I know, is offering these lockers at near cost - about $1100 in New Zealand where they normally retail at about $1599. He has also offered to fit the units free into diffheads, a service which usually costs about $350NZ. Price includes wiring, switches and compressor plus locker. James can update this information as needed.
Have waited to give this air locker a good workout before commenting, but after using it on a dozen trips/tracks am happy to recommend them as a good reliable unit to isuzu club members. It has had no issues at all and could not ask for better than that. To have a selectable option at this low price is a big plus.
I think its rear only at this point. Wonder what it would cost to send them to Oz?
