HUDY Titanium Pivot Balls for Precise Handling

The HUDY 990102 Titan Pivot Ball uses titanium to lower mass while keeping component strength. Supplied as two pieces, each ball is 4.9mm in diameter with 3.5mm spacing and interfaces via a 3mm hex for a sturdy, repeatable fit.

Titanium Advantages for RC Builds

Reducing unsprung and rotating weight helps maintain sharper steering response and consistent suspension action. HUDY's exact machining minimizes play and helps the pivot balls seat accurately under load.

Suitable Applications and Fit

These pivot balls fit many competitive touring cars and tuned off-road machines that call for 4.9mm ball hardware. They are commonly selected as a lightweight upgrade to refine balance and handling characteristics.
Remark :
Due to limited stock availability, please notice that some HUDY items may have to order from the factory and the ready time is around 8-12 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.

How should I install the HUDY pivot balls?

Clean the mating surfaces, thread the ball in using a 3mm hex driver, check that the 3.5mm spacing aligns, and verify smooth free movement before final tightening.

Will I need adaptors to fit these?

If your model accepts 4.9mm ball cups and the stated spacing, adapters are usually unnecessary. Measure the seat diameter and spacing first to avoid surprises.

Are these suitable for vintage kits?

They can work on older kits provided the cups are in good condition and match the 4.9mm specification; you may need new cups or shims if wear has altered the fit.
