I'm not sure who was asking about it, but there was a thread just the other day about drilling front leafs to move the axle. Would you consider these "lift blocks", in other words, would they be nay for the front end? http://www.offroaddesign.com/catalog/Zero%20Rates.htm

 

here it is.... https://www.ford-trucks.com/forums/7...g+leaf+springs

 

not really lift blocks, they are bolted into the leaf pack, they are pretty nice!

 

Thats what I figured. They're only an inch tall, so they're really not going to constitute any axle wrap. Plus they bolt into the spring pack, so I thought they would be good. 1.5 inches seems to be the safety limit on them.

 

I used the same ones on the rear of my 79 250 when I did the shackle flip to move the axle back 1.5"s, back to its original position (check my gallery for pics).


I wouldn't fear using them on the front end, they're bolted to the spring pack, no worries about loosing them, and they're short enough that they shouldn't add to spring wrap.

 

Thats pretty cool. Ive never seen those before.

Unrulee,
when you did your shackle flip your axle moved forward?

 

they are safe. just dont stack them

-cutts-

 

YES! I've read it both ways, no it won't change it at all, and yes it WILL push the axle forward.

I used a plum bob on the wheel well to mark the axle before I did the swap and after, and the shackle flip will move the axle ahead aprrox. 1.5". Zero rate's took care of that !

 

i dont fully understand how it bolts up

 

Unrulee,
never knew that. thanks for the heads up.

REP given

 

But now when the suspension compresses doesn't it make the axle move too far back?

 

Not that I've noticed. You could actually leave the axle 1.5"s ahead of stock, I don't think that there would be and clearance issues. I did it the zero rates for the 1" of lift and (hold on ) better appearance of having the axle centered in the wheel well.

 

but how exactly does it bolt up if you use it off center?

 

hm... after looking at them for a while now... I dont know. someone care to explain? I thought I understood it, but now it just doesnt work.

 

Look close at the pic of the blocks. There are 3 holes one recessed center, 1 recessed 1" (on the opposite side) and 1 recessed 1.5" (on the same as the 1" offset) You run the spring bolt through and put the nut in the recess with a little extra sticking out as a locator pin. Easy enough...
