new perches... extend wheelbase while at it?

[four_by_ken]

Just day dreaming at work a little bit.

If I stick with leaf springs on the Rockwells.... what would be the negative effects of of moving the perches back an inch on the rear and forward an inch on the front?

Basically the same idea as the offset zero rates.

The only trouble I can think of is that it also forces you to modify the upper plates that clamp them down.

On a 14BFF, it's as simple as drilling a new hole for the spring pin....I'm not sure HOW I'd do it for a D60 with that cast perch on the pumpkin side.

I haven't spent much time looking at Rocks to understand how the u-bolts attach, but there is probably a limit to how far you can shift that spring pin from center. I'd imagine if you were trying to move the axle 3" or more the center pin wouldn't even be under the top clamp anymore.....and I'd expect that would be no bueno.

I will be welding new perches on, and also making new top plates. Using new bolts, etc. It will be easy to move it.

I just am not sure what my limitations will be, and what the limiting factor will be.

I am thinking with the Rockwells.... I need to go as far forward as I can.

Any opinions?

Full hydro steering right? I would use some 52" or 56" springs in the front that will move it about 2.5-3"s depending on the mount location then redrill the perch, leave it centered. You should be able to move it forward at least 4 inches that will help keep the center chunk away from the oilpan

56" 8" lift springs. I guess I could make the mounts so that he lift is incorporated and just use stock 56s

Yes, full hydro.

im thinking about puttong 63 inch springs under my k10 buggy,with a shackle flip and 6 inch hangers,was there any issues when you done yours,what problems will i face

I think you will be fine with the k10 frame, but on my blazer frame there is a little hump in the frame right where I wanted to put the shackle hanger so I had to modify the frame a little bit

Still trying to figure out just how much I can move the center of my springs forward on my perches without messing up the suspension geometry.

I think for the Rockwell clearance, I am going to have to come forward some for sure.

I think I read on here that you can use 52" springs from a dodge to move the axle forward even more. The dodge springs have an offset center pin

I would rather not add new springs onto my list of stuff to buy... its long enough already.

haha thats understandable. I was just throwing that out there. Then I would just use your springs, mount them a little forward, then use a zero rate or re-drill the perch. You should be fine

New perches will be made and welded to the Rockwells, so I will try to include the zero rates into the perch.

Just curious how far I can move the centering pin forward?

Yea that's a tough one, I think 2"s would be ok, but I'm not sure about anything over that

M1028 on here (I think thats his username)... put rocks with 7-8 inches of lift. But, his front springs moved the mount forward about 3 inches. Doesnt seem that he has any problems with the pinion hitting the cross member or oil pan.
