Built For Real-World Use

Every CH4X4 Marine Grade Waterproof 12V 40 Amp Relay with 4 Pin Harness is laser-etched directly into the switch face — not printed or stickered — so the design holds up to years of sun, wash bays, and trail use instead of fading or peeling off. Sized to the OEM-style dash opening used across Marine applications.

Frequently Asked Questions
