    I crank my bars up for the winter to plow. If you need it year round I would also recommend the leveling kit. I have to go turn mine back a few turns no that the snow is done here.

    Hey bud I orginally told you I was running 285/75/16 on stock with not leveling kit which worked. Went and got the leveling kit for my truck, and with minor trimming I have 305/75/17 on 17x9 MT rims... they do rub in reverse and if i hit a bump at full lock.. so would recommend goin a size smaller than that. Just a little more help buddy

    I was talking to some local guys here who have the same year truck as I do. 97 Sierra 4x4. They were saying that the kits was a waste of $$ for the OBS style trucks and just crank the tbars 2". I'm kinda confused about the whole cranking vs kit for my style of truck

    I cranked my bars for awhile but lowered them back down once I bought this new camper(wanted everything to sit level). Basically what your doing by just cranking you bars is extending your shocks all the way out,not good. You can by longer shocks though. Also your tires wear out faster because they're angled now. Do it right and go w/ the full leveling kit,little more money but cheaper than ruining your vehicle.

    Just to clear this up. Torsion key leveling kits work the same way as "cranking" your bars. The difference is that the indexing or "clocking" of the new key allows the torsion bar to be adjusted more than the stock key allows. Typically on 1/2 ton trucks you can only get 1 inch of lift from the stock key whereas some aftermarket keys give 3 inches. This does increase shaft angles which obviously generates more wear. This is just my opinion but I think 3 inches is the limit before the wear becomes adverse, and I also wouldn't recommend any serious off-roading with a torsion key lift, that really requires a full suspension lift.

    Ok then. So according to all you guys with way more knowledge than on this, the new torsion keys in my 97 will be better for my front end components and ride quality than just cranking the bars and is worth the money. Thats the route I will go.

    New keys won't be "better" for your front end components, but you will get more lift than adjusting the stock keys. I adjusted my stock keys before I put on the Pro- Comp keys and I found the ride to be kind of soft and spongy, after the new keys the ride was much firmer and more "truck like", and I gained 3" of lift. The manufacturers make claims that "ride quality will not be affected" and " no wear on front end parts" but that is just impossible, new keys are not "magic" keys. The ONLY thing they do is allow you to adjust the ride height more than the stock keys allow, period!
