Jr. Sprint | Jack Shaft Housing – 2025 Design (JRX)

Price range: $81.99 through $106.49

New style jack shaft housing for our updated D1 JRX junior sprint motor mount assembly. Now more user friendly.

NEW jack shaft housing design – no more sawed-off Allen wrenches to set right-to-left location. A G8 hex head in the jack shaft plate pocket only requires a 1/2″ wrench on the bottom side of the plate.
OPEN housing design makes bearing maintenance easier. Removing the extra material let us beef up the jack shaft mounting plate to reduce harmonics.
Will pair with the JRX jack shaft mounting plate (old design).

Bearings sold separately. Choose to purchase with bearings and mounting hardware.
