...the transmission you rebuilt for my SCCA Spec 7 RX7 performed flawlessly this race season. It helped me in setting 3 track records, running an undefeated season, and winning the Rocky Mountain Division Series Championship.




...thanks for doing such an excellent job on rebuilding my transfer case! It helped me power my stock block Evo to the world record running a 9.959 @ 138.67. I now have the world's fastest stock block Evo.




Jacks is the only shop I'll send my GT-R, they are honest and upfront. Jack stands by his work and builds a very reliable built motor and built transmission!
