SSD RC SCX10 II Portal Knuckles (UPDATED!)
lets start with the good things about these knuckles, they are reasonably priced and easy to install. You can get overdrive with just swapping positions of the gears in the knuckle and you get almost 25% over drive. The knuckles are low profile so they do not jack your rig way up. the gear ratio is closer to the stock ratio than any other portal gearbox. SSD makes a slick fitting weight that fits direcltly on the knuckle. All in all a great concept. Now for the bad news, the leverage added by the portal knuckle on the SSD housing at axle tube joint can easily spin the metal tube in the plastic housing and rip out the screws. The axle CVDs are weak and can easily break if the front tire gets bound up between some rocks. The last thing is that there are no replacement front axle shafts available from AMain, I was told to contact the manufacturer for parts. They have a good concept but poor execution in the design.

The portal axles seem to be of high quality. I have not had time to install just yet however I think I will be pleased
