stock 01 duramax. kinda have that 2WD look, also looking to fit bigger tires. can i jack up the torsion key or what is the best possible way? im looking for maybe 2 inches of lift, but refuse to do a body lift.

please and thank you.

 

is it 2wd or 4wd? a leveling kit is always a nice cheaper solution. you can crank your torsion bars but it puts more stress on everything and will wear joints out a little faster

 

Most GM leveling kits are just clocked keys for the torsion bars anyways aren't they?

You could just turn up your stock torsion adjusters and see what that does for you. Only benefit to a leveling kit is that you can crank the torsion bars up even more (because of the different clocking of the key.) Either way, you get some height, but your ride takes a bit of a hit...

I know you can fit 285/75R16s or 285/70R17s on a Durasmack by just cranking the stock adjusters up a bit. All that costs you is the price of a good alignment. Any taller tire than that and you're pretty much stuck with buying a real lift kit.

 

yes, although nicer ones come with shock extender tabs.

 

That is one way, or for $1000 you can have the Cognito levelling kit installed. It'll raise the front 2-3" safely and drops the differential down a bit too so everything stays aligned properly. That is what I'd recommend if you plan on keeping the truck.

 

one thing i might add about the green keys or leveling keys, dont even buy them, it just re indexes the torsion bars so when you do crank them up it will force of the bars will just puch even harder down against the front suspension and wear it out faster, You can only go so much with the stock control arms before you get problems and stock keys have enough to do that.

First problem you see with keys or maxing out four t bars is some people rip the front shocks in half, but that can be fixed easily by adding the shock extender or buying a longer shock.

Second problem, with the green keys when you go sled pulling ideally you would want the font end to be as low as possible (to some extent) but with green keys when you pull the adjusting bolt out the front end is still raised and you will do nothing but pull really bad or break something.

Third problem is getting them installed, this is something you dont want to do on a budget, the tortion bars are under alot of stress and without the proper tool you can cause erious injury or worse.

My two cents is just raise up one side of the truck by the frame and put some antisieze on the bolt and crank it up 3 turns, if the height stays below two inches of what it initially was you really don't need an alignment. Then go to the other side and repeat.

oh by the way, my truck fits 315/70/17's lowerd
