Your engine. Your gauges. Our cluster.
Three platforms, one 12.3-inch widescreen cluster: carb-and-senders, Holley EFI, or GM E38. Pick how your engine talks, choose the artwork, and send us the build sheet. The preview is the real LCR artwork running a demo pass.
Demo values, not a live feed. Your final artwork is made by LCR from this build sheet for your 12.3-inch screen.
How does your engine talk?
Pick the one that matches what's under the hood. You can change it any time.
Inputs
Tell us what's installed. Defaults are our recommended setup.
Artwork
Both styles are finished LCR artwork. Colors change live in the preview.
Carbon Pro ships with its race faces: oil, water, volts, nitrous, plus fuel pressure, IAT and AFR readouts. Want different faces? Switch to Blue Lightning, or note it on the build sheet and we'll re-letter them.
