I am not a paid spokesperson or relative, just a loyal customer that has two H3s and puts full trust in this shop & individual cited below.


Hummer Parts And Services | Hummer Service
Located near St. Louis, MO just off I-170.


Short History-
After Lynch Hummer went out, Jim Lynch opened Adventure Accessories,
which was just acquired by the St. Louis Car Museum.
My wife bought her H3 from Lynch in 2006 and has always had Jason Reed, one of the original Lynch Hummer techs wrench on it (we drive 2 hours to keep it away from any stealership chimps).
Jason was also brought onboard at HummerService.
We went there today to have work out of my range done on it. I plan to get her H3 a new engine in the future and will have Jason do the swap.


Bonus - if you are into muscle cars, vintage caddies and wow factor vehicles the St. Louis Car museum is free if you are in the StL area.
