    I'm sure this has been asked before, what tire size looks best with a 3" body lift on a 3/4 ton? 285/75r16s or 315/75r16s? My dad has a 3" body lift laying around, so I am looking to use that than spending thousands of dollars on a suspension lift.

    Getting close to the time where I am going to be lifting my 1999 Tahoe... Closer now with the black Friday sales. I have an early build 99 Tahoe so I think the kits that fit the 98 and sites say won't fit the 99' should work correct?

    My original plan was to go with Superlift 4-6" in the front and use the 4" Skyjacker leaf springs in the rear because I don't want to stuff a large block in there. After doing research and seeing everyone saying that the Skyjacker leaf's are garbage I want to avoid them... Could anyone tell me what the best leaf spring lift for Ride quality towing and a bit of off-roading? I was also going to attempt to fit a Hellwig Helper spring in there also.

    Thanks' in advance

    Looking to do a small suspension lift on my 1998 k1500. does changing out the upper control arm actually lift the vehicle or would I still have to crank on the torsion bars? im looking for 2-3 inches of lift but want to keep my ride quality.

    heres an example of what im talking about https://www.summitracing.com/parts/sja-c2567k
    will probably use a block in the rear instead of the add a leafs.

    When using lift springs instead of blocks do you have to source a wedge to correct the pinion angle? Because the lift blocks are tapered to correct the angle or am I missing something about using lift leaf springs.

    I had a shop install a 6 inch lift on my 92 k1500, and it has some rake still. Will cranking the torsion bars in the front seriously affect ride quality even with a lift? its a rcx kit.

    It will affect ride quality. How much, I'm not sure.

    New to the platform.

    My question is:

    Is there seriously no way to lift a solid 3" on the k2500 4x4 trucks?

    I know I can crank in the front up to a couple inches but not sure I want to go straight to a 6" lift.

    Want to do something like the 3 attached but they all look to have more than just a crank but less than a full drop 6" kit.

    Other question is:

    I have seen people mention just going with the rcx 6" kit and just not cranking the keys up and leaving out the rear aal and that will net roughly 4".

    Is the torsion bar crank related to or functionally act like a spring rate? Or do they return the same functional spring rate regardless of the degree of crank?

    And if that is true, would you have to get an aftermarket set of torsion bars to affect the "spring rate"?

    I was about to reply to your first post but you pretty much answered your own questions here. You've got it figured out.

    EDIT - Alternatively you could do a 3" body lift. I'd prefer a suspension lift if it were my truck but I know there are several people here running body lifts that like them.

    Also I never clarified but yes cranking the bars will increase spring rate and ride quality will suffer.

    Thanks for the info.

    I am just having a hard time imagining how the geometries for these IFS trucks are so much different than other IFS vehicles that you cant run more than 1.5-2" suspension lift up front without wrecking your front wear items and ride quality.

    I have run 3" of suspension lift on many other trucks/SUVs without too much adverse effects to the driveline or steering/suspension components over many thousands of miles. (I.e. no new upper control arms etc, just plop in new springs and struts for 3" lift).

    For instance, why is it not more common to just see simple diff drop and key lifts between 3-4" on these trucks?

    I understand most of the conflict comes from the front bump stops but those can be trimmed/reworked simply enough I'm sure. Why is it that the only option is a full front drop?
