Yokomo YOKZCTB39 Titanium 39mm Tie-Rods Set, 2pcs  [YOKZCTB39]

39mm titanium turnbuckles for fine setup

The Yokomo YOKZCTB39 consists of two 39mm titanium turnbuckles intended for use on scale RC models. They act as adjustable links between rod ends and ball cups, enabling precise length tuning without the need to change fixed rods.

Choosing titanium reduces the chance of corrosion and cuts down on weight compared with many steel options, which can help preserve steering feel and suspension response across repeated use. Regular checks are still sensible to detect any wear.

To install, thread the turnbuckle into compatible rod ends or ball cups, set the overall length required for the setup, and secure according to your model's rod end geometry. Since thread pitch and ball cup styles differ between manufacturers, confirm the 39mm overall size suits your parts before final fitting.

Use in tuning: small length adjustments will alter toe, steering throw, or anti-squat; using both pieces allows you to mirror changes across an axle for comparative testing.
