12° aluminium lower caster block

The Yokomo YOKIB41312 aluminium lower caster block is a direct-fit replacement for DRB and DIB chassis, delivering a fixed 12° lower caster geometry in a machined aluminium alloy with a blue anodised finish. It modifies lower suspension pivot stiffness and front roll centre characteristics for 1/10 scale touring cars while leaving other steering parts unchanged.

Fitting is straightforward for experienced builders: remove the standard knuckle or hub carrier, replace the original lower caster block with this aluminium unit, and reinstall the factory fasteners. Standard hex drivers and a stable work stand are sufficient; always verify thread engagement and suspension geometry before running the car.

From a setup view the aluminium block gives firmer suspension response under load compared with softer materials, and the defined 12° caster helps with consistent steering return on medium- to high-traction surfaces. The blue anodised finish aids corrosion resistance and makes setup checks quicker.

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 this replace the stock lower caster block without modifications?

Yes. It is made to mount in the same location on DRB and DIB chassis using the original mounting points, so no chassis drilling is normally required.

Do I need different screws to install it?

Most users can reuse the factory fasteners, but always check the thread engagement and tighten to an appropriate torque to avoid stripping or loosening.

How does the 12° setting change handling?

A fixed 12° lower caster influences steering return and front grip, generally producing more predictable turn-in and steadier steering on higher-traction tracks.

What is the finish and corrosion protection?

The part is machined from aluminium and finished with blue anodising, which helps resist wear and makes the part easy to identify during setup changes.
