These are compatible with the stock Losi cups and the IRC UHD Centre Hardened Steel cup set: IRC4022.

If you are searching for a replacement to the LOS252090 coupler this will replace that piece and will include and upgraded driveshaft. If you need to replace afront side CVD Drive Shaft and coupler you can purchase the SRC252091.

These may have some compatibility issues with drive cups from FLM due to the increased size of the ball on the end of the dog bone.
