Nice shafts. The shafts are a direct fit and it only costs a few minutes to mount them to your M-chassis. Mine came without a grub screw construction as a previous reviewer stated so 'Yeah' may have changed the design. This means the shafts are not serviceable.
A nice addition to you M chassis. I have been using these on all my FWD minis and compared to similar shafts I have found these to be by far the strongest particulaly when used with a brushless system. Be mindful to keep the tiny grub screws tight at all times. I use some thread lock to prevent them from coming out. They will deteriorate and wear rapidly if these occurs.
Perfect fit in my M03L, These have got rid of the chatter you get when on full lock from the tamiya axle set up. and have removed a lot of play from the front. Would highly recommend if you have upgraded your diff as you can be left with a lot of play in the standard drive shafts. Another quality product from Yeah racing.
really good product, so nice I ordered another set. only negitive is that they are not servicable., but for the price just replace them with new. I don't feel that there is any need to buy expensive universals while these are available.
This is my second pair of these and are for my friends M03R. He wanted a set after seeing how good mine were and losing a couple of his dogbones from the stock set-up. They have run maintenance free and are still in great shape after 1 season of carpet racing.
