Machined 12° lower caster block in aluminium

The Yokomo YOKIB41312 is an aluminium lower caster block made for DRB and DIB chassis, providing a fixed 12° caster layout in a precision-machined alloy with a blue finish. It adjusts lower pivot stiffness and front roll centre geometry to influence steering feel on 1/10 scale touring cars without touching other steering elements.

Installation suits competent hobbyists: detach the existing steering knuckle or hub carrier, swap in the aluminium caster block, and refit the original bolts. No specialist tools are required beyond common hex keys and a secure car stand; always double-check suspension alignment after installation.

In track tuning the aluminium block gives a firmer response under cornering loads than plastic alternatives, and the 12° geometry supports consistent caster behaviour for circuits with medium to high grip. The blue anodise reduces visible wear and speeds visual setup inspections.

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.

Will switching to aluminium affect my bump steer?

Yes. Because aluminium is stiffer than plastic, expect subtle changes in steering response under suspension travel; check bump steer and toe during setup to compensate if needed.

Is the 12° caster suitable for low-traction surfaces?

The 12° setting is generally tuned for medium to high traction. On low-grip surfaces you may find less initial turn-in; consider other geometry or tyre choices for low-traction tracks.

How does the anodised finish hold up?

The blue anodise provides a protective layer that reduces visible wear and helps resist corrosion, though impact damage can still occur in collisions.

Should I change other suspension parts when fitting this?

Not strictly necessary, but after swapping to the aluminium block verify roll centre and camber behaviour; small adjustments to shocks or camber links can optimise handling with the new caster geometry.
