Kyosho IFW414-01 Rear Hub Carrier Bush Set MP9

This is the bush set for Kyosho's IFW414 aluminum rear hub carrier in the 2.0mm offset configuration.

The bushes are the inserts that sit inside the hub carrier where the hinge pins pass through. They are the actual bearing surface the suspension pivots on, and they are deliberately made as replaceable wear items so that when they open up you renew a cheap insert rather than an expensive machined aluminum carrier.

Worn bushes matter more than their size suggests. Once play develops at the rear hub carrier, the wheel can move under load, and that shows up as rear toe and camber that change as the car corners and accelerates. The result is a car that will not hold a consistent setup between runs and feels loose on power, which is easy to blame on shocks or diffs when the real cause is a few tenths of play in a plastic insert.

These are the bushes for the 2.0mm offset version specifically, so confirm which carrier you are running before ordering. Kyosho lists this across the Inferno MP9, MP9 TKI2 through TKI4, MP9e TKI4, MP9e Evo. and Inferno GT3.
