ZJTBLL ATV Speedometer Gauge Cluster Replacement for Polaris Sportsman/ATP 2004–2012 — Direct-Fit, Adjustable Backlight

ZJTBLL 3280431 is a direct-replacement multifunction ATV speedometer gauge cluster engineered to restore full instrument readouts on compatible Polaris Sportsman and ATP 500 models from 2004–2012.

When an original instrument cluster fails, ride safety and convenience drop quickly—this aftermarket assembly provides the same core displays and warning indicators as the OEM cluster so you can get back on the trails with accurate speed, RPM, fuel, temperature and service information. Built from ABS and metal, the unit resists wear and corrosion while offering adjustable backlight brightness and a shock-resistant design suitable for off-road conditions.

How does this gauge cluster match my Polaris original?

The ZJTBLL cluster is designed to replace several factory part numbers and aligns with OEM mounting, connectors and gauge layouts for straightforward swap-in installation. It reproduces the key readouts and indicator lights so your ATV behaves the same as with the original cluster.

• Replaces OEM numbers: 3280431, 3280482, 3280528.
• OE-style housing and connector pin-out for direct fit.
• Displays: speed, RPM, fuel, water temperature, odometer, trip, hour meter.
• Built-in warning lights and engine diagnostic indicators.

Which Polaris models and years are compatible?

This assembly fits a wide range of Sportsman and ATP model years commonly affected by cluster failures. Confirm fit by comparing OEM part numbers or by matching dash connector and mounting points before purchasing.
