TF 2.5 Lift Issues
First things first. Before we even run the potential of getting off track. I'm the kind of guy that takes responsibility for my own work. This post is not a complaint, and I'm not one of the types that posts when I modify my rig and blame everyone but me.
I bought the springs in the front Tera 2.5 BB with shock extensions. The install went as good as one can go. On a run into town I stopped by a loading dock. Before I get even close to compressing to the bump stop while flexing the tire hits the coil bucket.
There is a note about ".... for max performance ... wheels or spacers...", which is a massive paraphrase. I didn't really want wheel spacers. I don't have the budget for wheels.
I thought of grinding the coil bucket, but I think the lip is there to add rigidity. Plus I don't think it will be enough. It is not a centered axle issue, because the other side is only an 1/8 inch from the bucket at about the same compression.
Anyone flex one of these lifts with stock wheels and see this result?
As it may matter:

Just curious, but which bumpstops do you have? and are the bumpstops over compressing when you are flexed like this? I have seen the extended bumpstops "overcompress" and allow too much up travel. You ever look at this before the lift and see how close it got?
I have bumpstops that attached to the axle and never had the problem you show, never discoed my front with the stock tires either.

I have the ones that press into the stock bump stop position. Then you push in the stock ones in the pocket below. No bump stops are touching when the pictures were taken. Truthfully, I'm really not flexed out all that much.
I can't imagine Tera sells a shorter bump stop anyway, so it seems unlikely that they got the wrong part in the box. They did seem to have some trouble filling the box before they shipped it , and several things were missing. There was no packing list to verify what should have been in the box. Now you have me worried.

I don't think anything is wrong with your lift, I just think you are getting some great flex, much more than I got. It may just be because you can disco your sway bar.
I personally didn't like the way the bumpstops were that came with the lift, I have 3" bumpstops that bolt to the axle.
Did you ever happen to look at the flex when you had the stock suspension? Just curious if it gets close like that stock.

I guess either the people that run this lift with stock wheels don't off road disconnected, don't flex disconnected and check things out, or just don't have a clue.
At this point I'd say that wheels or spacers are required off road on a Rubicon model (with the variations of this lift), since you could easily destroy your tires with the push of a button. Funny too because now TF includes the front disconnect kit with the lift kit. Now everyone can cause the same damage without even removing a bolt. Based on the new parts in the kit, I would now say "wheels or spacers" REQUIRED. The "can I use stock wheels" question is common enough around here, and it seems to me the common answer has changed.
I have another off road trip planned in a few weeks. I'll have to run with the ASB connected or take off the lift. For my wheeling, I think I will be better off with the lift.

I think a small bumpstop extension would solve your problem. I would get bumpstops for a 3-3.5" lift and I would bet the problem would be solved.
Bumpstops don't cost much either.

How do you figure Rubob? I have three inch bumpstops an I don't seem to be riding on my bumpstops. The only time the bumpstops touch is when flexed, at which point they are doing their job and preventing the tires from eating my fenders.
I don't know everything but I can't see how limiting the up-travel by half an inch would hurt things here.

Only problem I have is rear axle shift... the rear trackbar drop bracket fits into the frame mount, but the bolt holes don't line up. Left it off for now. Have to get it on before hitting Rausch Creek this weekend!
