Default Making Big Coil Spring Spacers

I have 2 ideas for this and would like some input on them. I need to achieve around 4"-6" of lift.

Idea 1:
Make a custom block (have a large cnc machine at work) that will fit above the axle and below the coil spring seat. Then weld the block to the axle and the spring seat to the block. I would also make some kind of machined clamp for the top and bottom of the spring to hold it in. The thing i'm worrying about is axle wrap. What do you guys think?

Idea 2:
Make a custom block that will go on the top of the coil spring and bolt into the original top spring mount. I would also make a custom machined clamp for the top and bottom to hold the spring in. Which is better?

If it's a linked suspension how will you get axle wrap?

If it is the f150 style with radius arms, I have made blocks before for lift but not at the bucket end but at the diff. This way you can build tappered blocks to correct pinion angle. 3" is the largest block I have used. Be careful not to rotate the diff too far as this affects you caster alignment and will make your truck skittish like a SHOPPING CART.

ya its a 1978 F150 with a 460. Probably should have put that in the beginning lol.

But as it sits right now (and I bought this way) it has 2 coil springs that are spun together for the lift but that seems realllllly dangerous so I want to fix that. For the shock mounts there was just some fabbed up steel to lower the top mounting location to create lift. But I already got new shocks (the right size). So I dont think that I would have to do anything with the pinion angle because its fine now.

As far as axle wrap goes I was thinking because you can get it using too big of blocks on leafs.

Idea #2 is a lot better than idea #1.

I would re-work the front buckets. They should unbolt from the frame, if I remember correctly.... remove them, add in a sturdy spacer, then attach the buckets to the spacer. A large piece of 3/16 or 1/4 wall rectangular tubing should do the trick.

@Hagger:

Good idea! That made me think of another idea that might work. What if I unbolted the front buckets and flipped them over then bolted them back on upside down?

haha well my plans for this weekend are to either flip them and remount in the stock spots or weld some rectangular tubing to the frame and remount the top mounts to that.

I will take pics either way and post them tho.

if you unbolt them, or cut the rivits, move them down, there are four holes, move the top bolt to the bottom and drill a new set of holes.

Nets about 3" of lift and isn't stupid
