Yokomo S4-002BFLA Left Front Aluminum Bulkhead for YZ-4S  [S4-002BFLA]

Left Aluminum Bulkhead Built for Precision

The Yokomo S4-002BFLA aluminum front bulkhead fits the YZ-4S chassis and serves as a lightweight, stronger alternative to the factory plastic part. Precision machining reduces flex at the front end, helping deliver more predictable steering and control during fast laps.

Durable Machined Construction

Forged from high-grade aluminum, the S4-002BFLA provides increased rigidity without a major weight penalty. That improved stiffness helps the suspension settle faster and keeps the car composed through aggressive cornering.

Engineered for a Direct Fit

Built to match YZ-4S mounting points, this left-side bulkhead installs cleanly with common hand tools and minimal setup. Accurate tolerances help retain the car's intended geometry so tracking and alignment remain consistent.
