MR-4TCSD titanium upper I arm upgrade

The Yokomo YOKSD007T is a titanium upper I arm set supplied for use on MR-4TCSD-designated chassis, offered as a direct replacement option where the product listing specifies MR-4TCSD compatibility. As an RC-scale suspension component, the assembly functions as the upper link in the front or rear suspension upright geometry, affecting camber and roll centre behaviour when installed.

This kit focuses on material upgrade rather than geometry change: using titanium aims to provide higher rigidity and wear resistance compared with typical plastic or aluminum stock arms, which can influence feel and repeatability during set-up. Use it to refine suspension response during tuning sessions, keeping in mind alignment and bearing condition have direct impact on measured performance.

Specifications

  • Item Upper I arm set
  • Material Titanium
  • Model Number YOKSD007T
  • Compatibility MR-4TCSD

When replacing upper arms, check fit to the MR-4TCSD mounting points and confirm ball studs and bearings are compatible; this titanium set is intended to serve as a direct material upgrade within the existing suspension architecture.
Remark :
Due to limited stock availability, please notice that some Yokomo 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.

Does this YOKSD007T require any chassis modification for MR-4TCSD?

The YOKSD007T is listed for MR-4TCSD compatibility and is intended to match the original mounting points. You should still compare your chassis revision and existing ball stud layout before fitting to ensure correct clearance.

How does titanium change suspension feedback?

Titanium raises component stiffness and wear resistance versus many plastics, which can reduce unwanted flex and yield crisper feedback during cornering. Expect subtle changes in feel rather than large geometric shifts.

Will I need new ball studs or spacers?

Most installations reuse the original ball studs and fixings, but verify socket fit and thread engagement. Replace any worn studs or retainers to maintain proper engagement and avoid play.

Should I recheck alignment after fitting these arms?

Yes. Because material stiffness alters flex under load, it is good practice to re-measure camber and toe after installing the titanium arms and adjust as required for desired handling.

How do I maintain titanium upper arms?

Keep pivot areas clean and inspect for wear at ball-socket interfaces. Light lubrication of moving parts and prompt replacement of worn retainers will preserve fit and performance.

Where can I verify kit contents for YOKSD007T?

Refer to the vendor product listing or the packaging for a parts breakdown to confirm the number of arms and any included mounting hardware that comes with the YOKSD007T set.
