This is a Locked Up RC replacement part.
• 5 x 43.5 drive gear shaft
• Steel construction
• Tighter pin hole than stock part.
With this shaft you can use an Axial style spur hub to remove your slipper.
You will need the hub (this will not work with a slipper).
This part is designed to help eliminate drivetrain slop so the pin hole is a force fit. You may be required to press/tap your 1.5mm pin into the hole.
