Adjusting torsion keys WITH a leveling kit?

[MattLTZ]

:edit: 2009 Silverado 1500 LTZ

I have searched and searched and keep coming up with nothing on this subject...

 

Can you- adjust torsion keys .5-1inch with a 2” block leveling kit already installed?? Or is this going to cause too much stress on my front end suspension?

 

my issue is, I put 275/70r18 BFG’s and I’m running pretty bad. Already cut inner liner but still rubbing edge of fender. 

 

I do do not want to NorCal mod the fender. 

 

I am am also wondering on top of bumping my torsion keys adding half an inch in front I want to add 3” leaf spring block out back to raise the rear because my truck saggs when towing the boat- do you think this will work with out adding too much stess on parts? 

 

Thank you for any input.

Well crap.... No wonder I couldn’t find any info while searching for this. My year truck does not have torsion bars. I feel like an idiot lol.

 

guess I’ll be trying to order a .5” spacer for

top of spring to add with my 2” front lift and find a larger block for the rear to get the rake back. I would rather go with the air ride in the back to help level load but it’s just not in the budget right now.
