Product Description
This is a diff lock for the vintage/old school Grasshopper and CW01 Tamiya chassis'. These include the popular Tamiya models: The Hornet, Lunchbox and Midnight Pumpkin.
When fitted properly it will lock the differential, providing equal power to both wheels (which is often preferred in off-road environments) and may also eliminate the side-to-side slop, which is common to this gearbox, without impeding rotation. It is designed to be fitted using the internal diff pins but is tight enough to be fitted without them. It has also been designed to be a tight fit for the axle shafts with hex ends so you may need to use a bit of force to press fit the shafts into the diff lock. Please be careful not to use anything sharp and/or pointed, or a hammer, as you might damage the axle shafts and/or the diff lock. The hex end of the shaft will need to be properly aligned in order to fit.
This diff lock design has been test fitted on a new Hornet gearbox with a new set of gears and sealed metal bearings. Used gears, bearings and gearbox casings may cause variations in fitment. Also, please be aware that the 3D printing process may also cause minute variations in fitment. Light sanding in key areas may be necessary.
