I am a big rig mechanic and after having to torque u-bolts on the rear axle of a narrow spaced frame truck ie im lying on my back while holding up the torque wrench and not having anything to push off with my legs; That it would be a good idea to find a 3/4″ torque wrench that is either 4ft+ in length or 3ft with a pin hole for an expansion handle.
Unless someone knows that there is a higher torque the highest I would need to go is like 1780ft lbs. With a torque multiplier divide that by 4 so a 600ft lb is the highest i will need. I am looking for any brand recommendations or advice on it.
Also wouldn’t mind if people had a trick for a way to hold the end of the torque wrench up against the U-bolts. I see all kinds of makes and models so it would obv need to be adjustable to hold against the torque wrench head. edit: I feel really stupid bungie cord or belt for this problem.

I’m watching for recommendations too mdk. I don’t need one quite that heavy, but the range you indicate is probably what I will end up with. My initial need is for torqueing Powerstroke head studs. IIRC, they take about 350.
Maybe someone will show up soon with some usable feedback.
I like Precision Instruments spit-beam torque wrenches, they make a 3/4″ model up to 600 ft-lbs. Think the key for you is a custom reaction plate to work with the multiplier. Our AMSA shop guys fabricate their own for military vehicles from designs they find.
