I think I may have learned a valuable lesson...research THEN action! I recently bought a 2000 blazer 4X4 to haul kayaks and mtn bikes with. I wanted to put 31's under it on a wheel that stuck out a bit. (I like the wide look) At the suggestion of a friend, I did a Rough Country 2" susp lift. The 31's and MT Classics fit with a little custom trimming. It looks great, and I think I may even like it better than my 2500 Duramax! One problem...the inner cv joints appear to be trashing themselves, (surprise, surprise) and I realize now that this may not be a long term workable setup. What are my options? Kill the susp lift and go with 2" body lift? Thanks for any help.

 

a body lift would be a safe/reliable alternative solution, also once you replace ur cv's and go back to ur stock keys you can always do a small tbar crank (1.5" is a safe amount) and combine that with shackles in the rear.

 

That's just an inherent risk when you lift it. The 2" susp kits, for the most part, just adjust stock parts to their max to get lift.

You can try and fix whatever's wrong with the CVs (usually the boot slips and grease leaks out) or you can just replace them entirely.

 

I agree with these guys. However, how many miles were on the CVs when you installed the lift. They could have been about to die anyway. On my 1992 Blazer, cranking the torsion bars 2" ruined CV boots, but bringing it back down to 1 1/2" helped the squishy ride in the front and stopped the destruction of the CVs.

 

This issue has been discussed many times around this forum... I started a thread called 2" suspension lift gremlins that also talks about this.
Your solution is to replace both cv shafts with high quality units and crank the front end down about an inch. This is what I ended up doing and so far so good.
