Our water cooling jackets are made out of 6061 aluminum. Fitted with brass 90 degree fittings and 1/8" barb connection. Grooved on the inside with "O" rings for a good fit and seal. We make them as long as possible for maximum heat removal

Many hours of R&D and testing are spent to bring you a quality cooling jacket at a fair price.

Custom orders are always welcome.

A cool running motor is a longer lasting motor.

With modern Lipo power packs giving more power and longer run times it is a tough job to keep the motor running as cool as possible.

Compared to other shorter cooling jackets on the market, ours cover more surface area of the motor putting more water  in contact with the motor.

Each cooling jacket is hand machined and inspected for proper fit and size.
