Sup guys. I have a 2007 Silverado 4x with a Ready Lift 2 1/4 leveling kit on it. The drivers side cv boot blew out about 6k miles after the kit was installed. The truck has had about 70k on it before the kit went on. So I just noticed that the boot blew out once again, the passenger side has been OK.

The kit was installed by a pro mechanic, albeit not a 4x4 expert but the kits aren't rocket science anyway and yes the front end was aligned properly after installation.

Question, I was told that I need axle spacers. If that is true, what kind/brand should I go after?

Any and all help is greatly appreciated so thanks in advance!

Funny you mentioned it being cranked, I had a 2000 sierra that was cranked and I thought that was the coolest thing lol. Horrible front end handling if cranked too high which I did.

I don't have a classic now, its NNBS. Angles aren't bad actually. Its real close to stock angle.

Not to hi-jack your forum or anything, but why would you not crank a 07classic?? is it the same as all nbs? (silvy, Tahoe, 'burban, gmc)

You have something wrong if you are ripping boots with a 2.25 level every 6k miles. Without pics I can't tell much

That's what my mechanic buddy suggested, again his expertise isn't lifts/kits but he is competent. I am here to source the vast brain pan of experts here so I/we are open to solutions.

yeah those angles don't look bad at all.

just pick up some axles from a reputable parts shot that has a decent warranty so you can replace as needed. my guess is just bad luck or it could be getting caught on something like the brake like and ripping.

Is your diff centered in the mounts? There's about 3/4" of play in them so if it's to one side or the other it may be causing your issues. If not then it may be cheap cvs

The axles are new by the way, or at least they have about 3-4000 on them.

Will check diff alignment.

It's odd that your problem is with the outer boot. Usually the inner has more problems. I don't think angles is the problem. I'd look more for something rubbing or I noticed rust so I would also check the condition of the boot material. Does it appear to be rotting prematurely? The de-icer on the roads where I live shortened the life of my boots before, but not to a few thousand miles.

I have had good luck with ToughOne from Advanced. Lifetime warranty as well.
