Product Brief: YZ-2DTM3.1 Long-Wheelbase Main Chassis

The Yokomo Z2-002D31 is a hard main chassis developed for YZ-2DTM3.1 models in a long-wheelbase form to offer greater directional stability on dirt tracks. As a replacement part it alters the original chassis geometry and delivers higher longitudinal rigidity than the stock-length main chassis.

In day-to-day use the longer chassis modifies weight transfer and stiffness characteristics, which affects straight-line behaviour and provides a new baseline for suspension and tyre setup. It is intended for dirt use and for tuners seeking a longer wheelbase option within the supported car list.

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 vehicle variants are confirmed compatible with this chassis?

The chassis is listed as compatible with B-YZ2DTM31, B-YZ2CAL3, B-YZ2DTM3, B-YZ2CAL31 and the ROR-010 series including ROR-010RTR and ROR-010RTR-1.

Are there notable handling trade-offs with the longer wheelbase?

Yes. The longer wheelbase enhances straight-line stability and makes the car feel more settled on rough dirt, but it can reduce immediate turn-in response and agility in tight complex sections.

How straightforward is the swap from a standard main chassis?

Swapping is generally straightforward for those familiar with main chassis replacement: remove chassis-mounted components, fit the new plate, and check all mounting points and clearances before finalising assembly.

What setup areas should I re-evaluate after fitting this chassis?

Reassess ride height, spring choice and anti-roll balance, as the lengthened wheelbase and the stiffer construction will alter weight transfer and the car's handling envelope on dirt.
