What do we do?

******It is with great sadness that we announce the passing of our dear friend, Bruce Palmer. Bruce answered the phone at ZTherapy for 23 years. Bruce was a big part of the Datsun community and will be greatly missed.

Why use ZTherapy?

We make ball-bearing throttle shafts! Our carbs are fully replated, using the most expensive and durable process available. We don't plastic bead the bodies and sell them. We machine polish them to restore the factory shine. We make our own nozzles for closer tolerances and fix sticky pistons. Every part of the carb is treated like it is the most important part. Carbs and parts are covered by a 3 year warranty. If carb cleaner and silicone spray lube don't fix it, we will! Exchange and same day service standard (customer pays shipping). How many SU "rebuilders" engrave serial numbers on the throttle shafts? We do Datsun Z, Datsun Roadster 1500, 1600, 2L, SSS, GX, and Volvo HS6 carbs. They all get ZTherapy Roller Bearing Throttle Shafts.
