Quick torsion bar question

[Bear Lake Cruiser]

I need to raise the driver front about 5/8 inch to level the front of vehicle left to right. I am satisfied with the current rake. Is it best to adjust the torsion bar bolt with the front tire static in the operational position weighted on the ground or hanging free unweighted with the frame on jack stands? Also, any idea how many turns the big bolt goes to yield 5/8 inch lift?

Hanging in the air. I read 1 turn is ~1/4".

Just completed some turning myself, go to the FAQ and pull the word doc or PDF - they are your friend.
As how much for turn, depends on your vehicle and the current load on the bar - mileage, age, weight and how many jumps you have taken... just kidding, but I don't believe there is a formula. my measurements have changed each time I drive it a short distance, it is trial and error deal for me. I would turn one full turn and then re-measure. Dont forget the alignment - my Camber went visually positive with 2-3 turns.

You'll also need to drive it down the street and back before you re-measure to let the suspension settle out from being jacked up.
No need for jack stands. Just jack it up by the frame and reach under from the side with your breaker bar and socket. Don't need to get under the truck.

fwiw, 2 turns in my experience = about 1/2-5/8"
adjust with front tires hanging in air

Tape measure works very well.

Thanks guys, I think I got it covered. I will need to buy a socket, looks like 30MM according to this document. Have an appointment for an alignment on Thursday morning so I thought I'd give drivers side a couple of turns to see what shakes out. can anyone confirm that is a 30mm bolt so I can amazon one here by Monday afternoon? And I would suspect a 6 point versus a 12 point socket?

30mm is the ticket. 6 point is better if you have a choice.

30 mm 6 point here monday. Thanks
