The Yokomo S4-002BFLA aluminium front bulkhead replaces the stock left-side unit on the YZ-4S to reduce flex and improve feedback. Its lightweight construction helps the car respond more directly to steering inputs on technical tracks.
S4-002BFLA is made from durable aluminium to offer a long-lasting, low-flex mounting point. That extra rigidity supports crisper transitions and steadier corner exits without a big weight penalty.
Finished to match YZ-4S attachment points, the bulkhead drops in cleanly and keeps suspension geometry intact. This direct fit keeps setup predictable and reduces the need for corrective shimming.
