Precision aluminum rear mount for YZ-4/YZ-2DTM

This optional aluminum rear suspension mount is built for the 4WD YZ-4 family and designed to work with the L5 suspension arm. The RF version alters the front-side pin spacing versus the stock mount, decreasing the distance between the suspension pins by 2mm relative to the standard rear mount.

Used together with the matching rear mount Z4-300LRR and the 1mm longer L5 arm Z4-008RS5, the assembly permits a wider track while keeping the longer arm geometry intact. The result maintains the original roll characteristics while allowing a slightly wider stance.

On high-traction surfaces such as carpet or artificial turf, combining a stiffer suspension setup with this mount can promote a controlled amount of chassis roll and quicker turn response without upsetting the base handling. Balance adjustments are achievable by pairing with the 1mm longer front arm Z4-008F1.

Tuning role and installation notes: supplied as a tuning option; ensure correct pin alignment and sufficient clearances during fitment, then fine-tune springs and damping in small steps to suit high-grip circuits.

Compatibility: Supported chassis B-YZ2DTMW / B-YZ2CA / B-YZ2DT / B-YZ2DTM / B-YZ4
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 the aluminum RF mount withstand heavy running?

Aluminum construction gives added stiffness for tuning purposes; inspect pin bores and mating surfaces regularly and replace if you notice wear from frequent hard use.

Do I need the matching rear mount to benefit from this part?

For the intended wider track setup, use it with the rear counterpart Z4-300LRR and the 1mm longer L5 arm Z4-008RS5; adding the 1mm longer front arm Z4-008F1 helps restore balance.

Which track surfaces see the biggest change?

High-grip carpet and artificial turf show the clearest improvement, especially when you stiffen springs and damping to match the mount's geometry change.
