YZ-2CAL3.1 hard main chassis overview

This is an RC-scale hard main chassis designed for the YZ-2CAL3.1 family. The long-version layout increases wheelbase compared with the standard CAL3 main chassis to give a more stable platform at speed. The top surface is specified as a high-grip finish to alter tire loading characteristics and feedback during cornering.

Intended use is focused on on-track car control and chassis balance tuning rather than basic replacement; the part changes how the chassis reacts to suspension and weight transfer adjustments. Installation requires basic chassis disassembly to swap the stock main plate, and the chassis remains compatible with the YZ-2CAL3.1-related mounting points listed below.

Choose this main chassis when you want a firmer baseline for high-traction surfaces and a longer wheelbase to stabilise straight-line speed and mid-corner balance; pair it with incremental suspension and anti-roll changes to find the best setup for your track conditions.
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 chassis fit a stock YZ-2CAL3 without modifications?

It is designed for YZ-2CAL3.1-compatible mounting points; swapping the main chassis typically requires removing the original plate and reinstalling hardware to the same mounting holes, no major modification expected on compatible models.

How does the longer wheelbase change handling?

A longer wheelbase generally increases directional stability and reduces twitchiness at high speed, shifting tuning focus toward suspension and anti-roll adjustments to recover mid-corner responsiveness.

Is any special hardware required for installation?

Standard chassis mounting hardware for YZ-2CAL3.1 platforms is used; keep original screws and spacers unless a conflict is found, in which case consult the vehicle's parts diagram for replacement sizes.

What setup changes should I try after fitting this chassis?

Start with small changes: reduce front anti-roll or soften front shock spring rates to regain turn-in, and adjust toe and camber to optimise tire contact patch under the altered wheelbase and surface grip.
