These fit perfectly inside the alloy hubs that Yeah Racing has made for the tb-02, they look great are stronger than the factory plastic and add nice colour to a somewhat boring black chassis. I have never damaged one of these in all my time using them, would buy again!
precision fit, and they look great. Note the 'blue' is a bit lighter blue than on Tamiya anodised parts. Also when fitting to the TB-02 chassis I had to use some fuel tubing as a spacer threaded over the kingpin in the open middle section otherwise the plastic bushes worked their way out of the arms. Use locktite threadlock with alloy too or setscrews and balljoints will come loose.
