Integrated X4F motor and layshaft mount for tuning precision

The XRAY 303754-C unit places motor and layshaft supports into one precision machined part along the chassis centre line to preserve balance and symmetric geometry. The motor is set forward of the layshaft and a pressed-in steel axle maintains alignment under torque and impacts.

Retention is supported by 3mm alignment pins that keep the assembly located even when only a single fastener is used, reducing movement during crashes without relying on extra screws. The top surface is machined with holes to pair with XRAY top deck screws so the deck mounts flat and helps deliver consistent flex behavior.

Tuning is made easier with a top-access eccentric bulkhead insert for adjusting gear mesh from above, eliminating the need to remove the entire mount. Lower holes are countersunk for common screws which simplifies fitting across X4F configurations while preserving structural rigidity.

Produced from Swiss 7075 T6 aluminium with a black anodized coating, this component targets drivers who need a low-mounted motor position, predictable geometry, and rapid mesh adjustments during setup changes.

Remark :
Due to limited stock availability, please notice that some XRAY 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.

How precise is the fit for stock X4F parts?

This mount is made for X4F installations that keep the stock motor and layshaft geometry; precision machining ensures close tolerances for direct replacement fitment.

Will the 7075 T6 alloy bend under heavy impacts?

7075 T6 is a high strength aluminum alloy. While no part is immune to extreme impacts, this alloy combined with anodizing increases resistance to bending compared with lower grade materials.

Is gear mesh adjustment straightforward with this mount?

Yes: the top-access eccentric insert allows you to tweak gear mesh without removing the mount, which speeds pitside setup and testing.

Are special fasteners required for the lower holes?

No special fasteners are needed; the lower holes are countersunk to accept common screws, easing compatibility with different X4F builds.

Does the mount alter chassis flex characteristics?

By ensuring accurate top deck alignment and a lower motor stance, the mount contributes to repeatable flex patterns and more predictable cornering behavior when you change setup parameters.
