Is it necessary to jack up the front end to release tension when cranking up the torsion bars? I'm looking to raise the front 3/4 to 1" to get rid of the "jacked up" rear end look. I dont have access to a floor jack right now (mines shot) and i was just wondering if its really necessary to take some of the tension off before cranking.
Thanks in advance for any help.

 

I think it is easier on everything from the truck to your tools......

 

Might be a good workout if you don't lift the truck...

 

Is there a way to do a t-bar crank without buying those $100 torsion bar keys. They look like a socket thats it. Just wondering. if there is a way could you help me out.

 

Thanks for the quick replys guys.
I decided to try it without the jack... Cranked up easy as pie. I was really suprised.

 

I'm new to blazers. I have no idea what a torsion bar key is. I just used a 18mm socket to crank the bolts in to raise it. Crank them out to lower.

 

Ok torsion cranking does not need a key... it is really really easy and shouldnt take you more than 15 minuets... Look along your frame near the front door and follow that long black pole as far as it goes back... when it stops you will see a bolt that is not tightened all the way... clockwise tightens it to raise the front end... be sure to crank the bolts on each side equally... all you need is an 18 mm socket

 

is it bad on your suspension to crank the t-bars? ive never looked into it, but if it will give me some clearence, why not right?

 

I wouldnt reccomend it for a DD simply because it stiffens the ride and is hard on stock ball joints and related gear..

 

I cranked mine in the front to match the rear which i axle swapped. Front end has lasted pretty decent
