They are local to me, I have a gear change scheduled with them next month. No direct experience yet, other than scheduling the appt, but booked gear change based on positive feedback from other local jeepers. Hope this helps.
I went off-roading on club runs with the owner a few times in the first couple years he started business. Seemed like a nice guy and they have been in business for 10 years.
I never had them do any work on my truck at the time as I did all my own, but they did a lot of work to a friend of mines JKR about 5 years ago. Gears, axle truss, ect. Workmanship was good but I never asked the pricing.
