I am looking for a lug wrench that will provide up-to 405# torque.
It is for my C-5500 and the 19.5 wheel lug nuts.
In the past I saw a lug wrench that you swing and a heavy cross arm bangs on the lug nut and brakes it lose. It is like a impact hand operated
lug wrench.
Any help with the proper name or a place I could buy such a wrench?
Thanks in advance Lou Danes. Sorry if this is a confusing request.

Can't help you with the wrench you describe, but what about a 3/4" breaker bar (or 1", but those are a bit hard to come by) and a good chunk of pipe.

I assume since you are asking about lug wrenches this would be an emergency-type tool you need, but if you have access to a compressor to power it, an 1" impact can't be beat for torque. I've used Dad's on many occasions and haven't yet found something it wouldn't bring (or break, but I figure if it breaks it needed to be replaced anyway).

What you're looking for is made by Ken-Tool.(or at least that's who I get them from)...Part number 34441 (standard set) or 34442 (bud wheel set)
What this is called is a Shock Wrench... :)

On edit:
They say a picture is worth 1000 words, but this picture is kinda lousy, so it might only be worth 500 ):h

I like "Swing/Bang Lug Wrench". It sounds better than "Shock Wrench".:D
