    I have a 07 chevy 4x4 2500 with a 8.5 fisher plow on it. Sometimes front wheels hit wheel wells. I cranked up the torsion bar bolts 8 turns but I would like to crank them even more. How much can I safely crank up the torsion bars. I don't want to do any damage to the torsion bars. Also can you get hurt over tightening those bolts

    If i were you i would get a leveling kit and turn the bars down a couple turn, and that should do the trick for you. are you just looking to carry the weight better or looking for a nice stance when the plow is dismounted? either way i would think that they are to high but then again my buddy cranked his all the way up on a 3500hd srw for the stance!

    You can crank them alot before anything will happen. I had mine maxed out then replaced the keys with the 1/2 ton keys because they are keyed slightly more to start with and got even more out of them. 40k with not a single problem.

    After cranking up the torsions, remember you'll need a front end alignment. Hitting the wheel wells? Seems extreme. Are you running any ballast? You should be running minimum 500-600 lbs behind the rear axle.

    Forgot to tell you, I also put a1200 lb concrete block for ballast in the bed of the truck. And should I jack the truck up when I adjust the torsion bars.

    What size tires? Where is the weight in the bed?

    Move the weight back, as far as it will go. Build a frame or brace to keep it from sliding forward in an accident.

    Timbrens on the front will help greatly.
