What ya think of this fix?

So I'm installing my R.C. Lift and other than the typical issue with the spring shackle that I was told was fixed since the springs being built are longer and softer. I'm ordering low profile shackle relocaters for that next week. Here is something else I discovered that I wanted to address. The axle gets pulled about 1-1.25 inches forward of stock. This in turn pits the wheel/tire closer to the front side of the wheel well. I thought about the reason for this and thought it was due to flex would put it closer to center when compressed. Not sure if that's what happens but it seems a little in-probable.

You can see how far forward this is in relation to the bump stop.

What I ended up doing was relocating the holes in the top u-bolt plate and in the perch. I drilled new holes 1 inch forward in order to push the axle back 1 inch. Next is to make longer spring plate with a bolt on it to hold the spring pack together since now there's 1/2 inch not supported between the perch and spring pack. What I discovered first off after doing this is that the e-brake cable on the driver side is stretched at its limit on the 6.5 lift. Maybe this is why the springs are made this way... Dunno. However I on bolted the e-brake mount where the single cable connects to the two for the wheels. This I will move back roughly 3 inches to gain cable movement. But the end result is pretty substantial and nice in my opinion. I noticed this difference right away with both sets of springs off of the XJ and measured a bunch trying to figure why they would manufacture these this way. Has anyone noticed this when doing theirs? Are other lifts the same?( I doubt it) what's you opinion of this?


Much better now. Shocks are mostly upright now too instead of angled.

the axle moves rearward as the spring compresses.
drink a few beers and look at the shackle. it should become clear why this happens

Makes perfect sense... Why I didn't think of that. I'm still a little forward, I wonder if it'll be fine this way. I will be installing Napier flares on it when I get the money for them.

did you check it with the weight of the jeep on the springs?

I don't think he did. If so this thread prolly wouldn't exist

When I lifted my rear, 6" total, using HDOR relocation brackets and 1" lift shackles ... I had new perches and plates made to relocate the axle 3/4" to the rear. I got my measurement at ride height ... could have done without but I'm wierd about these things.

Exaclty what I though. The axle is just hanging, once dropped off the jack stands you woudl have realized the axle swings back into position.

I did with the weight of the jeep on the springs. It only compresses about half an inch. Doesn't move back hardly any. As the springs settle what I did here may be mute and ill have to put them back I'm sure... We'll have to see I guess.
