Cross RC (Crawler) Forced Differential Lock

It will force the differential to be locked at all times. Works on Front and rear axle. I did all three axles on my NT6. Simply teardown axle fully. remove spring and replace with spacer. May need slight size adjustment depending on printer. Don't forget to grease as you are already there. I did not like the spring style differential locks for Cross RC Crawlers. The springs would rust, loosen and the sliding mechanism would get caught after two years. This worked specifically with the NT6 and should work with others that share the same axle diff style. PLA but stronger would be preferred. Something that can take constant friction. I greased the piece with the rest of the axle and personally used PC.
