Add a leaf or blocks

[Oldyukon95]

I have 4wd 95 yukon with 6" lift. The rear axle is in blocks and one of them Has moved at least an inch. So I'm thinking of either replacing the blocks or adding a leaf. I do some offroading and pull a trailer now and again. What does everyone here prefer? Any particular brand for the leads? I know the leafs will make the ride stiffer but how much? Its not my daily driver but I do take long trips(2-3) hours in it. The install looks pretty straight forward for both. Any info would be great Ty.

I went with a combo AAL and Blocks. I had a 5.5 inch block when I first lifted. had some axle wrap issues so I downed to the 4 inch block and added a 1.5 inch AAL . your other option is a shackle flip which can lift you about 3-4 inches and then put a AAL .

I have both

So maybe flip the shackle and use a 3-4 inch block?

x2 on the shackle flip. Much more sturdy. I hate blocks. I realize that they're necessary but scary when you find they're awry. I took mine apart (superlift 4" kit) and found the pack bolt that sits into the block was rusted flat and had come off. The bottom of the block was not even in the hole in the perch. Scary crap. ORD makes a hefty kit. Good welds, heavy steel. I'm sure you're aware you'll need new u bolts. I'd flip the u bolts too so the threads are pointed up. Easier to work on and ORD makes a good kit. Again, good heavy steel. Hope this helps.


PS the shackle flip will require a zero rate spring. It allows you to move the axle perch bolt back so with the flip, the axle will remain in the center of the spring. Otherwise you move the axle forward 1.5" which looks funny and rides bad and will rub in the front fender. Zero rate block will give you another inch lift too.

Just make sure ORD sends you all the bolts and nuts you need. See my post about ORD quality.

Hope this helps

that is great! So what I'm gathering is flip the shackle her a zero rate spring and then use ord block to lift it rest of the way. Ty!

If I have a 6" lift should I get 3" blocks?

I only had a 4" lift kit so the shackle flip got me there and the zero rate gave me a little extra. The 6" kit might use a small block if it comes up short.

BTW, I'm not selling ORDs stuff and have no interest in their products. Having said that they do make good parts.

I looked at ord. They have a 4" shackle flip but it doesn't include blocks. So I'm guessing I need to get 2" blocks and zero rate leads as well right.

I think I would go Add a leaf and not a block if that's a possibility.

 

[Oldyukon95]

I read some more last night. I can add a 2" leaf with the 4" shackles. The zero rates might add an inch as well though I'm not sure yet. I'm probably going to email ord and see what's best

 

[Dneel81]

zero rate does add an inch. When i redid my suspension I figured out the torsion keys were maxed on the front end and it still has a little front squat to it. The 1" zero rate didn't help that any I'm sure.

 

[Oldyukon95]

Thx for the info. I'm going talk to ord and see what's the best way to go.

 

[Dneel81]

good luck man. And pictures too!

Personally, I'd stay away from blocks period. Do an add a leaf and a shackle flip. Blocks are an unnecessary evil.
