Hey guys I was wonder how much inches can you get with a stock torsion key when cranking on it?

Yeah I figured out the hard way lol I was thinking of putting the stock keys back but i would like to know if it’s possible to crank on the stock keys I’ve heard of guys cranking on the stockkeys to get some height but how many cranks to get to a safe height without putting stress on front end components?

I need a little more height clearance for my tires even though the ride is harsher my tires they were rubbing So I needed a little more clearance I don’t really do heavy off-roading mostly just in the sand.
In all of my thousands and thousands of off-roading miles, a lot of that in extreme off road rigs in Moab type conditions, my experience tells me the worst kind of off-roading on my equipment is sand. The only serious breakage that left me to be towed out was in sand. If you are trying to turn larger than stock size tires through sand, you are doing heavy off-roading.

I had too much traction and too much power. I had just rebuilt my front driveline and put a new set of Goodyear MTR's on my Jeep. Really soft sand and lots of traction don't make a very good combination. I should have put my wide bald sand tires on for that trip but neglected to. Good traction and pushing too hard and I blew the new front driveline. A little bit of lift from the torsion bars will add some additional stress to parts, but won't put excessive stress on your axles. The problem comes when you crank them to the point there is no suspension travel left. I have raised mine enough for an inch or two, gotten it realigned, and had no additional problems coming from the ride height. My '97 1500 Suburban had a 3" block on the rear and the torsion bars lifted just enough to help the 33" tires clear. I drove it like that for a long time and never had to change a ball joint or axle.

Wow really I would never thought sand would do that much damage than going over rock hills muds etc but Yeah I cranked my torsion a little to high and notice there wasn’t that much suspension travel so I had to crank it back down? But what would be the difference wouldn’t cranking down my aftermarket torsion keys be the same as cranking on my stock keys? My cv axles are at an angle and have driven them for some time and haven’t noticed any tears in the boot not to mention these are the stock cv axles.

IMHO, torsion key kits are nothing more than money grab some greedy person designed to dupe millions of dollars from truck owners. All they do is change the clock position of the torsion bar, which is the exact same thing you do by adjusting the original keys with the adjuster bolt. Who really cares where the key sits on the adjuster bolt? The stock set up can turn enough to bottom out suspension travel just as easily as a leveling key set does. Huge racket. Huge waste of money, time, and patience.

Hmm you do have a point. So what would your opinion be should I keep on the aftermarket keys or put back the stock ones and just crank it up? I’ve heard the cranking in the stock keys puts out more stress than having aftermarket ones? How many inches can I get by just cranking on the stock torsion keys without putting stress on the steering components?
