Precision Steering from Kyosho MZW703H Upper Arms

The Kyosho MZW703H Hard Caster Setting Upper Arm Set is designed for the MR-04 chassis to increase front-end stability and steering accuracy. It suits users focused on predictable handling and refined steering input.

Better Front-End Response for MR-04

Fitting the MZW703H upper arms increases caster rigidity to produce crisper turn-in and steadier lines through fast corners. The parts are produced to align with MR-04 suspension mounts for an accurate fit.

Long-Lasting Fit and Function

Made from robust materials, the Kyosho MZW703H Upper Arm Set maintains setup integrity under regular use and racing conditions. It is a practical choice for those aiming to lock down consistent vehicle dynamics.
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 these arms fit if I run different front hubs?

They fit MR-04 hubs and setups that retain the original mounting points; if you use nonstandard hubs check for clearance and mounting compatibility first.

What handling changes should I expect?

Expect firmer steering with improved mid-corner stability and reduced vagueness, which may require minor trim or toe adjustments.

How often should I inspect these parts?

Inspect mounting points and ball joint condition regularly, especially after impacts or heavy track sessions, to keep alignment true.
