get a 1" ada leaf, AJM likes the zero rate leafs that give you about an inch of lift.
but you can probably go to anytire shop and pic a set up for 50 bucks or so and theyll also give you about 1" and increase your load careing capcity too, and may make your truck ride just a nough rougher to notice,
sometime this week Im throwing a set of 3/4 ton leafs with overloads on mine, I should gain a lot of load capcity and 1" of lift since 3/4 ton leafs have one more leaf than my 6lug 3/4.
Does your truck sit nose low right now? Our trucks came from the factory that way, so if it sits level now, I'd think someone has already cranked the torsions a little. You might want to check on that.
Still, if your truck is a little bit high on the front, I like the http://www.OffRoadDesign.com 1" zero rate add a leaves that I have. You can read a write up and install at http://www.coloradok5.com/ordaddaleafreview.shtml about them. Good stuff. 1" of height gain with none of the side affects of an old fashioned add a leaf. Doesn't up your load rating any, but your ride and flex stay the same.
Tightening your torsion effects your allignment. If your not worried about screwing with the camber then go for it. You will cause premature wear on the outside edges of your tires and your steering wont act the same. Many guys talk about doing this but it doesn't make sense.
the tires will tilt in at the top wearing the inside edge,
1/2" of lift wont affect things a hole lot but any more and you can see the dif in camber, at least I can
And no cranking the t-bars wont wear the outside edge of the tire it will wear the inside edge. lowering the bars to much would wear the outside edge, I guess thats kinda trivial thought either way it will wear prematruley.
no, the the tires are in like this: /\ when you crank the torsion bars, and like this: \/ when you lower them. if you were to go do this right now to your truck, that is what it would look like. not trying to show you up or anything, its just that i am always lowering and raising the front end because of my stupid 2"-3" rough country lift.
