Jr. Sprint | Motor Mount & Jack Shaft Assembly (JRX 2025)

State of the art for the Jr Sprint world, our JRX Sliding Jack Shaft/ Motor Mount Assembly is like no other. Ease of use and reliability was in mind with this aluminum mounting system. Our JRX Motor Mount and Jack Shaft Assembly is made to make things easier! When we designed the D1 JRX, we kept simplicity in mind. Made specifically for the D1 JRX. This JR Sprint Jack Shaft/Mount Assembly utilizes motor slider pates just like a 600! No more laying in the dirt to move the motor!

• NEW – Jackshaft Housing Design (no more sawed off Alan wrenches to set right to left location) G8 hex head in Jackshaft plate pocket only requires a 1/2” wrench on the bottom side of the plate.

• OPEN Housing design makes bearing maintenance easier! The removal of extra material allowed us to beef up the Jack Shaft mounting plate to reduce harmonics!

• Reduced the amount of hardware fasteners to make assembly easier!
