    Okay guy I want to know if you guys would be interested in a new Product. They are called spring relieves. They are made by BC broncos and here is some picutres of them http://www.bcbroncos.com/suspension1.html. What I need from you guys is how thick is your rear springs are. I will let Chuck from BC Broncos know and he plans on making some sets up for Blazers if you guys want. These do lift the rear up 2" I believe. So let me know or Chuck and he can help you out. These things will help with your rear flex and you will not get as much frame flex either.

    Do you need to know how thick the whole spring pack is or just the individual leaves?

    I want the thickness of the hole pack. He will try to get a good average of the springs out there and make the kits to fit everybody.

    If you use good you bolts you will not have any problems. I have seen them in action and they work awesome and I have not heard of any failure. If you guys trash you bushing out this will fix it. Why do you think you strip u-bolts out because of the pressure you have on the u-bolts, you are trying to twist the spring pack in the spring perch. You get read of this action with the pivots.

    What about extra body roll on the street? Would they allow extra movment from side to side on the street?

    are they angled for the natural driveline angle, or would they come with the needed shims to return the driveline angle to stock?
    I have an overload spring that brings my spring pack to 3 inches, without that spring my pack is right at 2 inches.

    I am also concerned about Steves point, body roll on the street.

    No you should not have extra movement side to side but yes you will have more body roll because you are taking out the swaybar effect of the leaf springs. He said that he doesn't notice more body roll but some customer have said they see more body roll than before. I guess if you like how they work but don't like the body roll on the street put a sway bar on it with disconnects. I will let you all know how the work when I get a set.

    Hey hows it going.Hows that adapter going?When you get them tell me what you think.The two inchs of lift would let me use some stock springs.I don't think the short stick out on the bottom u-bolts would be an issue.Mine are cut about 1/4 past the nut anyways.Will thay be the same cost.

    Hey Dan, Yes I think that the price will be the same but I will talk to Chuck to be sure. I started machining on it but have not got the splines cut yet. I hope next week that will happen.

    I wasn't asking about side to side movement, I was wondering about the driveline angles would they be built to keep the driveline angle right, or would they require shims and if so does the cost include shims?

    No he makes them straight so you will have to get your own shims aleast maybe for the first couple sets. Then he will have a idea what people need for a shim and maybe he could supply it I don't know. When I get the first set I will figure out what I need and we can go from there.

    Yes I told him to make them for 3.25 tubes. The large housing fords are already 3.25 so that should not be a problem.

    Well they are kinda but I think that they work better than a revolver shackle. That is just my opinion on that. I think it makes your suspension more fluid and not so stiff. Chuck thinks they work so well that he is Patenting them which is not cheap to do.
