what's the best way to lift the front end of my avalanche? I have 20" wheels and BF Goodrich A/T's on it.

With a jack?

upside your head!!!

An Avalanche is just a Suburban with some missing roof. Anything that works for a Suburban will work for an Avalanche.

Here are some (not a particular recomendation.. just a search result)

thanks for the help!

everyones a jokester

Just couldn't resist, it's not often I'm the first one to respond to a post. How much do you want to raise it, might just tighten up the torsion bars a little.

I Am Pretty Sure, Not Positive, It Does Not Have Torsion Bars, Its My Brothers Avalanche, And I Am Sure I Would Have Looked For That.

I Am Going To Look At Eibach

Suspension is torsion bar, here is a link for some offset keys to crank up the tb's.
