Yokomo D-156-27AA Aluminum 27mm Rod end adaptor for Front lower A arm  [D-156-27AA]

This is certainly an aluminum rod end adapter you can use with framework for instance the YD-2 show or YD-4 designed with an A-arm change.
It's lighter compared to the metal adapter useful for the lower arm and it's also effective in improving exercise performance. It is much longer than the standard adapter in kit, making this ideal for usage with aluminum lower A-arms. Whenever found in combination with a resin arm, the supply size is supposed to be longer, leading to a wider tread.
