This is the replacement Kyosho Aluminum Knuckle Arm Set for the TKI4 buggy. These updated steering knuckles feature shorter steering arms to change the Ackerman angle, and promote increased corner speeds. By maintaining more correct Ackerman angle throughout the range of steering motion (especially at higher degrees of steering angle), there’s less slip angle, which means the TKI4 carries more corner speed than any Inferno before it.

Running these on my MP9 TKI4 and they were a drop-in replacement for the stock cast aluminum. I did not wait for the stock ones to break and I have run this set since the buggy was new with zero issues. Very strong and perfectly machined.

So yah, these are 100% compatible with the current production MP9 Evo. Not sure what issues the previous reviewer was having, but the key dimensions are identical to the extremely weak stock cast components. I would definitely recommend upgrading the plastic hub carriers in the front as well, I have the feeling that will be the next piece in the front to break.

Anyways, these components are flawlessly machined, I expect them to be much stronger. Definitely a must have upgrade for the MP9 Evo Readyset.

NOT compatible with MP9E Evo. I tried using them but now the universals keep popping out, as if they need to be longer. Bummer.
