    Have a 05 gmc 2500 hd with 7.5 western poly pro. Dealer put timbrens on but truck still seemed to sag. This morning I went under truck and cranked t-bars 20 1/4 turns or 5 full turns doing the math. According to measurements and what I've read I raised up front end 1". Truck holds plow better but not quite level with plow on. Am afraid to adjust any further to mess up suspension parts Bolts due have more travel and dealer said not to crank in all the way at all. Adjusting easy just raise tires off ground and use wd40 to lube good.. Any advice? Awaiting big lake effect in Cleveland tonight!

    5 turns to many to mess or just right. I have been reading thart most people seem to go 4 to 6 full turns. I aslo carry around with me a Toro 2 stage for the old people who do not want a truck on their drive.

    I turned mine about 5-6 turns about 2 years ago little rougher ride just a tad bit but soon as I put the plow on it drops it back down. That is on a 1500 chevy with a sno way 26 series steel blade.

    I've turned mine up about 4 full turns on my Chevy 2500 (not an HD). So far its made very little difference. I need a leveling kit

    I turn mine up 8 turns for the winter months to carry by Boss V-XT. The dealer did it when it was installed and I just drop it back down in the summer. I also carry about 600 pounds behind the rear axle for ballast. Truck is in my signature.

    You may want to get a allinement after cranking up your tbars. Also the stock shocks are too short when you crank the tbars causing them(shocks) to fail sooner. GM and most good suspention shops have shock extenders you can add to correct the problem. This is for the NBS 07.5-08. Not sure about the 07 classic or older.

    Take your truck in for an alignment now that you have it where you want it,,, you just changed the camber by cranking the bars to get lift.

    I have a 2005 chevy 2500hd with a western 8.5 pro plus and i cranked my t-bars 8.5 turns. if you have ever seen those leving keys, their just like cranking your bars up past what factory alows. you can crank them all the way in but your gonna throw off your alignment. what i found that works best is the leving torriosn keys and upper control arm kit( to correct alginment) about 700 for everything call hoose 4x4 in ham lake, MN

    Turned the bars 95% before end, around 9-10 turns. Have the timbrens... my 3500 sits lower than 2500s without the plow on it, makes me sad how much the plow affects the front end.

    I wouldnt worry about ruining anything been running this setup on 5 or 6 trucks.
