    First, damn it feels good to finally be able to afford the 25 bucks to join the site...lol. so i'll begin asking a few of my million questions today. I have a '72 Blazer that is currently torn apart. My suspension is what i'm trying to figure out right now. For the front suspension, I plan on using 52 or 56" custom built ORD springs with 5-6" of lift & their HD shackle. In the rear, I plan on using a 4" ord shackle flip, 6.5" ord HD shackle, and stock lift 63" springs. i just need the springs to complete the set up. I was wondering if anyone has any suggestions or gripes? open to anything before i invest more money. i was also wondering if the ord shackle flip and hd shackle will work with the chevy 63" springs? and i plan to run a 42-44 tire with tapered fenders. thanks.

    <------jealous hehe

    my guess is a lot of people will say you'll need more lift than that, but its possible to do it with trimming/narrowing you have in mind.

    One thing I was pretty suprised at was how far forward the rear axle moved after doing the shackle flip. I then used a zero rate to bring it back 1.5 inches which ended up being about right. Might want to plan for that unless your custom springs have a re-centered pin.

    With the setup you're describing, you're already pulled into the town of SuperCustomville.... population: YOU

    With springs that long (both front and rear) you've got plenty of custom hangerwork and re-inforcing to do. Based on that, you can make the ORD stuff work....you'll just need to build the new hangers to accomodate them.

    Sounds like a REALLLLLLY soft spring setup....are you setting it up for rocks and technical crawling?

    i'm setting it up for trail runs & rocks, but the more & more i think about it, i'm leaning more towards lifting it 15" and running 44s :confused: . i guess i'll find out how my plans unfold. i'll have to figure it out within the next couple of days b/c i'm getting pretty damn tired of switching my suspension set up often :doah:

    Saw your reply on my post. If your planning on narrowing your front and rear fenders, do that first and the figure out your suspension after. If you do it any thing like mine your ride hight will change in the narrowing process because of multple things like, no hard top, less sheet metal, axle position. That's why I am doing all my body work first then doing my suspension. I'm going to have 56-57" springs in the front and 65-70" springs in the rear and with 42's only about 6" of lift.

    I really liked the picture Greg posted in there. Sounds like your suspension setup will be pretty extreme. At that point, I would guess you are in the area of diminishing returns. It takes a whole lot of work to get that all to work, but if you have your heart set on it... more power to ya! Be sure to post some progress pics.

    What are your plans for steering and front spring mounts?

    ...well i've been thinking very hard on this topic lately, and my plans have changed...sounds easier to just lift it & run 44s...it's probably the route i'll go instead...build a trail rig when i finish school...
