Front hub bushing replacement for MP9

This Kyosho IF421-01 front hub carrier bush set is supplied as a replacement for worn locating bushings on MP9 front hub carriers. The components restore the intended clearance and movement between the hub carrier and steering components while preserving the original chassis geometry.

Compatibility: intended specifically for MP9 series hub carriers. It fits as a direct swap for the bushings that position the hub carrier on the front suspension carriers and is commonly fitted during preventative maintenance or when addressing play in the front end.

Installation notes: removal of the hub carrier from the suspension arm is usually required to gain access to the bushings. Basic tools such as hex drivers and pliers are commonly used—retain any shims or washers and verify alignment once reassembled. Ensure the hub rotates freely and steering motion is consistent before track use.

Tuning role: renewing worn bushings reduces slack and sharpens steering feedback, improving lap-to-lap consistency. This is a maintenance item that supports repeatable handling rather than a modification that changes suspension geometry.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will replacing the IF421-01 bushings tighten steering response?

Fitting new bushings removes play in the hub carrier pivot, which can make steering feel more immediate and consistent, improving predictability without altering geometry.

Does this part change the suspension geometry or track width?

No. The replacement bushings restore the original clearance designed into the MP9 hub carrier assembly and do not modify suspension geometry.

Can replacing worn bushings improve consistency over multiple runs?

Yes. Removing play and restoring correct clearances helps make steering feedback repeatable, which aids consistent lap times and setup retention.
