What this lower caster block does

The Yokomo YOKIB41312R lower caster block is an aluminum suspension part made to fit DRB and DIB chassis layouts. Finished in red, it imposes a 12 degree caster at the lower pivot to influence steering characteristics and setup repeatability on touring car models.

Its function is to position the lower suspension pivot and thereby define the caster angle used during cornering and straight line stability checks. When installed on DRB or DIB platforms it gives a stable reference for comparing setup changes between test runs.

Fitting notes: the block replaces the factory lower unit at the designated mounting point on DRB/DIB suspension uprights. No extra hardware is called out in this description; retain the original fasteners and follow the chassis supplier's torque guidance.

Specifications

  • Item: Aluminum lower caster block, 12 degree, red
  • Material: Aluminum
  • Model Number: YOKIB41312R
  • Compatibility: DRB/DIB

As a basic geometry component for DRB and DIB chassis, this lower caster block is intended for racers and hobbyists who need predictable front-end steering behavior for setup comparisons.
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.

What does the 12 degree rating define?

The 12 degree rating indicates the fixed caster angle the block establishes at the lower suspension pivot, directly affecting front geometry and steering response on compatible chassis.

Can I adapt this block to other models?

This product lists DRB and DIB as compatible. If you want to use it on other models, compare mounting points and dimensions or consult fitment resources before attempting installation.

Any particular installation steps to follow?

Ensure the block is oriented correctly for the chassis, secure it with the original lower mounting fasteners, and torque to the chassis maker's specifications. Check steering alignment after fitment.

How will this part affect on-track setup work?

Using a fixed 12 degree block creates a repeatable baseline for comparing other setup changes, helping you isolate the influence of caster on corner entry and front grip.
