    i run tuff country 6" springs in back of mine, they ride well for a highly arched spring, they have sagged a little since new, 3.5 years, but my truck's not exactly lite, and best of all they don't cost an arm and a leg.

    I've been pondering this and my setup will soon be stock 3/4 ton springs and a rear shackle flip. The front I think I will extend the shackle and shim the front mount. Not sure if anyone has done this in the front, I will make it beefy.

    How much lift can you get out of 3/4 ton springs?

    Why don't you try a shackle flip instead. It'll keep the same ride as stock springs but will give you 4". You can do it homemade style (Corey Perez did it as well as quite a few others) OR you could get new shackle hangers from Offroad Design. http://www.offroaddesign.com.

    If you were set on new springs, I would suggest the Tuff Country. They seem to be the best from all I've heard. There is a spring rate table under the technical section off the main page. It will give you some info on the softest or strongest.

    No lift with the springs, they are stock. The shackle flip can be made any length you want it. There is a good link..let me find it....http://www.offroaddesign.com/catalog/catalog.html

    Stupid question then but what's the diff between the factory springs and 3/4 ton springs? I'd have assumed some slight height gain due to the increase in load? Otherwise wouldn't you get more articulation with the softer stock springs?

    Its one more leaf for the 3/4 ton, yes they will be stiffer(higher load cap.). I always carry about a million lbs. of crap and people/dogs in my truck so my rear sags alot, they are $10 more than 1/2 ton so I will try them instead of helpers. Then I will make the front to level properly. Try asking Depdog about this, hes done just about everything to his truck.

    I am running SuperLift 51/2" Softride spring packs.
    Keep in mind most spring packs are made to Pick-Up specs and the rear of a pick up is much lighter than a K5.
    I have 4" in front and my rig sits level!
    I lovem and even could aregue that they ride better than the stock springs!!

    Rock ON!

    If you guys want really good springs, contact National Spring in El Cajon, California. Or Deaver Springs, also in CA. I'll have to track down the contact info. They will make springs to your specs and style of driving that are many times better than stock!

    Where did you locate the 3/4 ton springs? I want to do the shackle flip, and my 79 springs are, well, 20 years old. Any recommendations on rebuilding them or upgrading, as you did?

    Thanks.........

    What ever brand you go with make damn sure you buy 5.5" or 6 inch rear springs!!! Found out the hard way..replaced my rear 4" blocks with 4" Superlifts...you have to run 5.5's or 6's to get her to dit level...i currently have some 1" blocks in the mix as i had them laying around but will be ordering 2" blocks here real soon to get her to sit level. The extra weight of a Blazer Half-Top, fuel tank(31x8=248 pnds of fuel)..plus the tailgate make 4" inch springs sag down to the same height of 4" blocks!!! Just ask Steve over at ORD...he will second the motion!
