JACO Superior Products Lightning RX4 Tire Deflator with Gauge — Quick-Connect, ANSI-Calibrated

The JACO Lightning RX4 is a patented quick-connect tire deflator with a calibrated gauge that speeds air-downs for safer, repeatable off-road tire pressures.

Built for overlanders and 4x4 enthusiasts who need fast, accurate tire pressure adjustments on the trail, the Lightning RX4 combines a secure push-to-lock nozzle, instant quick-release, and an ANSI-rated gauge in a single handheld tool. It removes the tire valve core to speed deflation while preserving accuracy, and includes a protective pouch plus spare valve cores so you can maintain your rigs away from home.

How does the Lightning RX4 make air-downs faster?

The RX4 uses a patented valve-core removal system and a push-to-lock quick-connect nozzle that increases deflation speed compared with standard tools. The design both accelerates venting and gives a controlled, repeatable process so you hit target pressures reliably.

• Patented core-extraction accelerates air release.
• Push-to-lock nozzle secures instantly to the valve stem.
• Quick-release detaches with zero air loss for fast transitions.

Can I trust the pressure readings while off roading?

Yes — the built-in gauge is calibrated to ANSI B40.1 standards for consistent readings up to 60 PSI. That level of accuracy helps you set safe, repeatable tire pressures for varying terrain without carrying a separate gauge.

• ANSI B40.1 calibration ensures dependable readings.
• Displays pressures up to 60 PSI suitable for light-duty rigs and trailers.
• Integrated gauge eliminates the need to swap tools mid-adjustment.

What makes the quick-connect and quick-release useful in the field?

The instantaneous push-to-lock connection saves time and prevents fumbling at the valve, while the quick-release button lets you detach without releasing extra air. Together they reduce downtime and make multi-tire adjustments smoother when conditions are changing fast.

• Push-to-lock nozzle secures with one motion.
• Quick-release preserves set pressure and speeds tool removal.
• Ergonomic operation for gloved or cold-weather use.

What accessories are included and how do they help maintenance?

The RX4 ships with a small toolkit tailored to on-trail valve care so you can replace or service Schrader cores and store the deflator safely. Spare cores and a valve tool make it practical to address common valve issues without detours to a shop.

• Protective storage pouch keeps the tool and parts organized.
• Valve tool and four Schrader cores for quick roadside repairs.
• Compact kit fits in glove boxes, dash bags, or recovery packs.

Who is this for: The JACO Lightning RX4 suits overland travelers, weekend rock-crawlers, and any driver who routinely lowers tire pressure for off-road traction and wants a faster, more accurate, and more convenient air-down procedure. It’s also a practical upgrade for fleet and trail leaders who need repeatable tire settings and a durable kit that travels well.
