    We are looking to lift a 83 K20 longbed and want a 4 inch all spring lift for stance. He will be hauling a heavy duty landscape trailer as well as mulch, stone, etc. in the converted dump body so we want to put in heavy springs (not concerned about ride quality or flex JUST strength and resistance to sag) especially in the rear. Any help is appreciated. I want to get this out of the way so I can go back to working on my own stuff. Which lift spring manufacturer offers the stiffest/strongest 4" all spring lift?
    Thanks Chris.

    I would have springs made for your application. I dont know if you will find production lift springs that will suit your needs.

    My friend had 4 in. springs made for his 1 ton so he could still haul his heavy tool box a big diesel tank w/ pump and pull a goose neck trailer w/ a tractor on it, or a big horse trailer.

    As fas as production springs....That would prob be Superlift Swamprunners, if the even still make those.

    I get all the exercise I need pushing my luck! [​IMG]

    I have never seen nor heard of any aftermarket lift company making HD rear springs. [​IMG]

    The only HD springs I know of are the front springs.

    Superlift has the only rear springs that I know of that are HD and they are the 8" rears.

    Rancho Makes the stiffest brick riding POS springs out there for the front. You want to buy mine so I can put on the EZ's?

    I don't need no damn shop manual, I got a pornographic memory.

    You can do a couple of things...... First of all custom made rear springs......

    But I would go with a soft ride spring and add airbags with a onboard compresser to keep the sag out when hauling the extra weight.... that way you can adjust for the weight and still keep the ride nice when it's empty along with flex....

    There is a chart that has all the springs and their rates somewhere around here. There was a post a few weeks ago about it, take a look around.

    Displacement, cubes, and did you say you drive a riceburner???

    4 inch. Plenty of pictures in the link in my sig. They were $400 or something new. I'd take $225 and shipping.

    Well they sure don't sag do they? LOL I guess that 520 inlb rating solved any sag complaints and life time warranty claims! I can JUMP on my front bumper and the tires will give but not the springs and my truck is a pig with lots of extra steel on it. I figure is I could find a 700lb winch that would be about enough to improve the ride.

    Rough Country springs have a pretty stiff spring rate.

    I know Superlift has HD springs in 4" springs. They are right there with the Ranchos, regular Skyjackers, and Rough countrys. I would probably buy Grims springs for cheap and add some rancho add-a-leafs to the rears. If that doesn't do it you will need to look into getting either a custom spring or start looking for some tow truck springs.

    Ranchos are by far the stiffest I've ever ridden on - Why not go for the best of both worlds - a set of soft-ride springs, and a set of airbags?
