Performance-Grade Rear Bulkhead for YZ-4SF2

Replace the stock rear section with the S4-002RRA to stiffen your Yokomo YZ-4SF2 chassis. Crafted from aluminium, this right-side bulkhead improves structural integrity and offers a firm platform for suspension components during competitive running. It is aimed at drivers looking to refine handling under aggressive conditions.

Balance and Ride Quality

The aluminium bulkhead reduces flex and helps the suspension keep consistent geometry, which can improve mid-corner balance and traction. The part's weight distribution supports a more planted rear end while remaining suitable for common touring car setups.

Installation Notes and Fit

Designed to mate with the YZ-4SF2 factory mounting points, the S4-002RRA installs without cutting or modification. Hobbyists can expect a neat fit and a reliable upgrade path when replacing the original plastic bulkhead.
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 bulkhead suit modified shock towers?

If the shock tower maintains the original mounting pattern, the S4-002RRA will fit. Significant tower modifications may require checking clearances before installing.

Can I run this on carpet or slick tyres?

Yes, the added stiffness benefits both carpet and hard-packed surfaces by keeping the rear geometry consistent. Tyre choice and setup will determine the final handling feel.

Does the S4-002RRA require different screws than stock?

It uses the same mounting points; standard hardware from the YZ-4SF2 can be reused. Inspect screws for wear and replace with stainless fasteners if preferred.

How does this affect crash durability?

Aluminium resists wear and bending better than plastic under normal use, but it can transfer impact forces differently. Check mounts after heavy impacts and replace if necessary.

Is polishing or coating needed for maintenance?

A simple wipe down and inspection is sufficient. Anodising or a protective finish can help resist corrosion, but is not required for performance.
