I use Evan, who is located in Bayshore. His number is 516-384-5349. I have been dealing with him for years and have never been let down; he's honest, won't do work that isn't necessary, has a ton of experience, is a member of Long Island Offroad (so he walks the talk, too) and is fairy priced...in addition to putting two of my lifts on (TJ and JK), he has even custom welded detachable stairs for my JK.
While I'm sure that there are other good mechanics on LI, I will never use anyone but him.
Give him a call when you get the chance and you won't be disappointed.
Hope it helps and good luck!
