I am looking at buying a new torque wrench what is the maximum torque specs we need for our trucks.

well for the wheels it is one that will go to at least 140pounds. but for the engine we dont need that much. i have a 3/8 torque wrench i use the most. it will need to go to 10 pounds to about 100 for the engine work.

I bought a snap on 3/8 that i use for most of my engine work... I would also like to get a snap on 1/2 as i find myself in need for one often and have to borrow one from a friend. If you do a lot of engine/transmission work i would get a 3/8 and 1/2 wrench. If its just for tightning lugs i would go with just a 1/2 and probably wouldn't go with a snap on unless you wan't to spend more money that doesn't neccisarily have to be spent.if your just tightning the lugs the wrench doesn't need to be as acurate as if you where building a engine

....stay accurate, set it to zero when it's not in use, and do not use it to break anything loose. Tighten only.

The highest is 240 ft/lbs for our trucks and that is for retorquing the crankshaft balancer bolt and re-using the same bolt. If you use a new crankbalancer bolt it is a 2 pass sequence of 37 then 140 ft/lbs.
If you don't do this, you will have problems with thte crank spinning on the snout.
The are now 2 problems,
1) is alot of the specs are in inch/pounds so you have to divide by 12 to get the ft/lbs so you don't strips out things. My advice is to do the math in the manual and write the ft/lbs in red if you are not also going to get a inch/lbs wrench.
and
2)some of the ratings are like 89 inch/lbs (intake manifold bolts) and that ends up like 7.42 ft/lbs and off the scale for alot of wrenchs. alot of torque wrenches that go to 240 start at 10, 15 or even 25 ft/lbs at a min

That's why I have more than one. Small torque wrench for light duty (in.lbs) and another for heavy duty (ft.lbs)

Yep, 2 are needed in my opinion. Other thing is that wrenches with high torque ratings are not as accurate on thier lower settings.

Yea, that crank bolt torque number is crazy. I have 3 torque wrenches (SnapOn 1/4, 3/8, and 1/2"), and still end up doing math to convert inch pounds to n/m to ft/lb, etc. The 1/2" one doesn't start until 30 ft/lb, and doesn't go up that high (can't remember exactly how high). I can tell you this, don't spend a mint on a SnapOn torque wrench, but don't skimp and get something made in Taiwan either. I'm sure that something from the Craftsman catalog would be more than adequate

Definately need atleast two! It's actually nice to have three +
I like having 1 inch pounder, a 20-100ftlb & a 50-250ftlb and you almost need a torque angle meter now-a-days with all of GM's "ftlb spec + 60 degrees + 45 degree" type torque specs... Sure you can "adlib" but they came up with those specs for a reason, and not cause they want you to go buy a torque angle meter..

Good advise!!

You might want to consider two.....1/2 and 3/8.............Boy the Matco guys loves me..

Good idea on the degree wheel flipper, most overlook that and guess.
