    Hey guys, getting ready to put a 4" lift on my 86 Burby. It's currently a 1/2ton, but swapping in 3/4tons at the time of the lift. I would like a 4" lift with 35" tires. Soon after the lift, I plan on installing a Winch/bumper combo...which wieghs around 200lbs.
    What is a good set of front 4" springs that wont become 2" springs with the wieght of the winch/bumper?

    Any help would be great.

    Aren't those stiff as heck? Or is that what I'll be stuck with if I want a winch/bumper combo?

    I have heard good things about procomp springs... but dont know how heavy duty they are. Summit sells them for like 96.00 each. And their shipping surcharge on them is only like 6.00. it is a good deal since they are heavy to ship.

    "What is a good set of front 4" springs that wont become 2" springs with the wieght of the winch/bumper?"

    A set of 6" springs?

    Not sagging under weight is the exact same thing as high spring rate. High spring rate=stiff ride.

    You can always get an inch back by adding a 1" zero rate or some longer shackles. Those things would be easy to take back out if you were removing the extra weight. As an example, I am putting in shackles soon with two upper holes. Then with the hardtop off, I can get an extra 3/4" in the front to level the truck and give more room for the rubber. This will change the pinion angle by less then 2 degrees, too.

    I put a 400lb bumper on my front end with the 4" Rancho front springs (non-HD) and it didn't sag at all. What it did do was make the front end ride better.

    BDS suspension. The springs are pre-sprung so to speak, meaning that they have settled as much as they are ever going to. Plus they have an unlimited life time warranty. It doesn't matter how you break it or how many times you break it, it's replaced free. As soon as I can, I am putting a new 6" system on my blazer. I wish I would have gotten them in the first place.
