Signal Forged CL40 Center Lock Series Forged Wheels
Signal Forged CL40 — Center Lock Series Monoblock Forged Wheel
The Signal Forged CL40 brings a bold multi-spoke design to the monoblock center lock forged category. Machined from a forged T6-6061 aluminum billet on a HAAS CNC mill, the CL40 is produced as a single structural unit — no bonded or bolted joints between hub and rim. The center lock interface is machined integrally into the forging for maximum load transfer and geometric precision.

Wheel Care
- Clean with a pH-neutral wheel cleaner and a soft microfiber brush. Avoid alkaline and acid-based cleaners — they can etch the brushed and polished finishes used on Signal Forged wheels.
- Rinse with cool water before applying any product, and never spray product onto hot rotors or hot wheel surfaces.
- Apply a dedicated wheel sealant or ceramic coating every 3–4 months to protect against brake-dust etching and UV.
- Torque lug bolts to manufacturer specification and re-check after the first 50–100 km of driving.
- Inspect for curb damage regularly — forged wheels are impact-resistant, but any kerb strike should be checked by a wheel specialist.
