how big is he looking to go? as with anything suspension wize for the excursion, i would reccomend contacting cary(obswiz) for a set of v and b code springs and his custom valved blisteins. i have the springs and will be getting his shocks shortly.
I sent my buddy your info and told him to call you with exactly what he wants, also told him that you guys come highly regarded. His name is Brian and i'm not sure if he called or not yet. But he told me he'd be calling before he buys anything to see what kind of deal you can work out.
