    Can someone point to a good thread on turning up torsion bars on a 2010 2500HD 4800 lb front axle plow and tow prep package?

    I am looking for a discussion of benefits and disadvantages as well as a how to.

    Is it possible to turn them up too far? Is there a way to gauge the proper amount and can they be turned up too far?

    Are there any things you need to know to look for, such as problems that may arise after you have done so?

    GM has a spec called the "z height" for these trucks- it's a range for the maximum height recommended by GM- if you stay within the confines of the "z height range" you shouldn't run into problems. Will cranking up your t-bars wear out front end components faster?- somewhat yes, but with my t-bars having been cranked on both my pickups for over 75K on one and 60K on the other with no front end issues, I'd say you won't run into problems unless you're really abusing the truck. Best bet IMO if you're trying to keep the truck from "bottoming out" with a plow on the front- crank up the bars a few turns- GET AN ALIGNMENT, add timbrens to the front, and run a few hundred pounds of ballast against the tailgate- been doing it this way for several years now always worked well for me!

    Not to steal your thread but is there any pros vs cons in installing either3/4 ton or one ton t bars on a half ton pick up with a plow.

    Besides a stiffer ride? No. All pros, one con.

    Hey 06sierra do you think 3/4 ton bars and keys be plenty enough then?

    Is it even possible to put 3/4 one ton bars on a half ton?

    You do not need bars and keys. Keys are a waste of money

    What are you trying to do?

    As long as its not a 4 door Tahoe, yes, its completely possible. i believe its possible on a 4 door tahoe too if you move the t-bar crossmember back because for some unknown reason GM decided to put shorter bars on the 4 door. While the 2 door had truck bars. As did the Suburban.

    A 4800 lb. front end rating on a three quarter ton truck is just fricking ridiculous in the first place.

    Ford and Dodge still offer those ratings. As does Chevy. My 04 GMC 2500 does fine with the 4800. Never bottomed out with an 8' HD. Completely stock, hell I think the bars might have been turned down a little.

    Don't know about Ford, but Ram (Dodge) does NOT offer a 4800 lb front end in a three quarter ton truck. At least not from '13 until now. The lightest front end rating they have is 5,200 with a hemi, and 5,500 with the 6.7.

    I had a fisher mm1 on before i had to sell it and it just made the front squat pretty good. Since i learned so much about them i would just rather get another one of those

    I have my torsion bars cranked in my 3/4 ton to level. I had my last truck, a 1500 series blazer,lifted with the tbars. If you're just looking to get the weight of the plow up a little then it's no big deal, however if you're looking to lift the truck that way and you overcrank you may start blowing through cv axles. If you really crank them you could get about 2-2.5 more inches but your CV angles will deteriorate swiftly. Whatever you choose to do with them make sure you get an alignment asap after touching them.

    Jesus might as well call it a heavy half. Then again...2 of my rigs have 3600 FGAWRs, and one with 3925. And one with 4800.
