Lightweight Aluminium Rear Bulkhead Built for YZ-4SF2

Fit the S4-002RRA to your Yokomo YZ-4SF2 to gain a more rigid rear section. This aluminium right bulkhead is engineered to improve the structural backbone of the chassis while keeping mass low for nimble track performance. The part balances durability with usable weight savings for club and regional racing.

Handling Improvements and Durability

Aluminium construction reduces unwanted flex at the rear and helps maintain consistent suspension geometry under load. Drivers will notice improved predictability on corner exit and reduced chassis deformation during hard braking. The bulkhead integrates with common touring car setups.

Easy Swap and Chassis Compatibility

The S4-002RRA aligns with the YZ-4SF2 factory mount points for a straightforward replacement of worn plastic parts. Installation is quick and does not require chassis modification, making it suitable for hobbyists wanting a reliable performance upgrade.
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.

Can I use this bulkhead on the left side instead?

This S4-002RRA is cut for the right side and will not match left-side mounting geometry. Look for a left-specific part number if you need the opposite side.

Will aluminium increase wear on bolts or screws?

Aluminium is harder than stock plastic but softer than steel hardware. Use proper torque and thread locker where recommended to avoid loosening; stainless screws are preferred.

Is any setup change required after fitting?

Minor setup tweaks may improve balance after fitting a stiffer rear bulkhead. Consider small adjustments to rear shock damping or toe to fine-tune handling.

Does this part affect battery or electronics fitment?

No significant changes to battery or electronics placement are needed, as the S4-002RRA keeps the standard YZ-4SF2 mounting layout intact.
