What is Height of Power Mountain Tallboy Off Road Bottle Jack When Retracted and Extended

Updated 12/31/2025 | Published 12/25/2025

Question:

I know the Power Mountain Tallboy can lift, with attachments, 6 ton to 37inch and 12 ton to 27. How high does the just ram/piston NO attachments lift on the 6Ton and 12ton jack?

Hey Andersen, without any type of attachment installed on the Power Mountain TallBoy Off Road Bottle Jack part # PM34FR the height is 9 inches when fully retracted and then 15 when extended. The lift range is right around 6-1/2 inches. Would that work for you?

Is that the same for the 12 ton?

The Tall Boy Jack is packed in a carrying case like it is fragile, I guess so it doesn't rattle around or damage items stored along side it in your vehicle. I unpacked it, checked its operation, and measured its height. See pics if available, I don't see a way to add my pics. The piston reached a height of 17" without any of the extensions or the "U" axle saddle on top. I purchased this jack to use as an emergency jack for my new travel trailer as my former trailer was much lower. I like that it is a combined jack and jack stand. Should be safer to use on the roadside or off the road. I hope I never have to use it!

@BJ Thanks for passing that along! When our installer had one out he measured that when at it's highest without an attachment it was 15 inches but maybe he had an earlier design or something. I'll take your experience as the correct number and will update my answer!

not only is the maximum extension important but the minimum as well especially if there’s a needs to a jack slip under an axle or suspension assembly. Using just the bottle jack extension sleeve with one of the cap attachments the minimum use height is about 11”.
