Stiffen the Rear of Your MP9 with the Kyosho IF423

The Kyosho IF423 Rear Lower Suspension Arm is a key upgrade for builders aiming to tighten up handling on MP9 series cars. Made with the Inferno MP9e TKI in mind, this arm gives a clean fit and added toughness so you can count on predictable handling during competitive laps.

Engineered for Track Durability and Control

Kyosho designed the IF423 to resist the knocks and stresses of hard racing while keeping steering response crisp. Its sturdy construction supports the rear suspension geometry for improved traction and steadier behaviour through fast corners.

Fitment and Simple Installation

The IF423 fits Inferno MP9 series models, including the MP9e TKI, and installs with standard hardware for an easy swap. That makes it a practical choice whether you prepare a race car or refresh a weekend basher.
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 the IF423 work with older MP9 generations?

The IF423 is made for the Inferno MP9 series and fits current MP9e TKI layouts; older chassis variants may need checks for clearance and pivot compatibility before fitment.

Does this arm change suspension geometry?

The arm maintains factory geometry but its stiffer build can make the rear feel firmer, which often improves stability at speed without altering mounting points.

Any tips for installation and maintenance?

Check pivot pin fit and apply light thread locker where required. Inspect the arm after heavy hits and replace if you notice cracks or excessive wear to keep handling consistent.
