Are you referring to a "torque multiplier"? If so, search Google for plenty
of sources. Here's one, but I have a feeling the link won't work:

It worked for me (with careful cut and paste work), but this
does not look like what the original poster is looking for.

This is a geared torque converter.

What he is looking for is an extension which offsets the socket
by a precise distance. When set in line with the bar of the torque
wrench, and extending past the head. The effect is to add length to the
wrench, so the torque reading is actually lower than the actual torque
applied at the end of the effectively longer lever.

As others have pointed out, while this extends the range of the
wrench, it reduces the accuracy. And if the extension is not in proper
line with the main shank of the torque wrench.

The way this works is that you need to apply a given force on
the torque wrench handle (at a precise distance from the socket). The
wrench is actually measuring the force. By extending the socket to
beyond the head, you are applying that force on a longer lever, you are
producing proportionally more torque at the actual socket.

What you found is probably a better choice in reality -- but is
certainly more expensive. If the original poster is looking for this to
keep costs down, and does not care about the loss of accuracy, what he
is looking for is probably the best choice -- btu I'' bet that he could
find a torque wrench to cover the range that he needs by a quick eBay
search, and keep the costs way down that way.

I'm set, up to 600 ft-lbs, thanks to a surplus sale many years
ago.

Enjoy,
