Dynamic now rebuilds and restores gearboxes and rear axles. Gear setups and transfer cases too!

We do not do fabrication, example: housing end changes, traction control or bracket swap welding, housing shorting,

tube replacement or any other mods besides adding c-clip eliminators.


Our service is for upgrading to different gear ratios, rebuilding musclecar housings and building new 9" ford center sections.

Our manual transmission service is focused on rebuilding and restoring the classic American muscle car 3, 4, & 5 speed units of the 60's and 70's era.

We also can rebuild Transfer cases for the popular American trucks and Jeeps, as well as the GM SM 420.

All Units MUST be removed from the Vehicle and delivered to our shop.

We do not have facilities to accomodate in-vehicle repairs.
