JACO Superior Products Lightning RX4 Digital Tire Deflator with Gauge — 10" Hose, ±1% Accuracy

The JACO Lightning RX4 is a digital tire deflator and gauge that delivers rapid, controlled airing down with a lightning-style quick-connect nozzle and ±1% accurate digital readout.

Designed for off-road drivers who need fast, reliable tire pressure control at the trailhead, the Lightning RX4 combines a push-to-lock Lightning nozzle, a precision digital gauge, and rugged construction into a compact kit. It speeds the airing-down process, minimizes air loss when disconnecting, and gives readable, repeatable pressure readings so you can set tires to the exact PSI you want.

How does the Lightning RX4 speed up airing down?

Instead of screwing onto the valve stem, the patented Lightning push-to-lock nozzle instantly attaches in one motion for faster connections. A quick-release button detaches the tool without losing tire pressure, allowing sequential deflation across tires with minimal downtime.

• Push-to-lock Lightning nozzle for immediate, airtight connection.
• Quick-release button lets you remove the tool without air loss.
• Up to roughly 200% faster airing down than screw-on deflators in typical use.

How accurate and easy to read is the digital gauge?

The RX4’s professionally calibrated digital gauge displays pressure in 0.10 PSI increments and maintains ±1% full-scale accuracy across a 2–100 PSI range. The clear readout makes it simple to set consistent pressures for on- and off-road conditions and reduces guesswork when dialing in traction.

• 0.10 PSI resolution for precise adjustments.
• 2–100 PSI measurement range covers cars, SUVs, and 4x4s.
• ±1% full-scale accuracy ensures consistent, repeatable readings.

What features make the RX4 durable for off-road use?

Engineered with aircraft-grade anodized aluminum and a corrosion-resistant finish, the RX4 stands up to outdoor use and trail conditions. A 10-inch braided nylon hose provides flexibility and abrasion resistance so the unit keeps working even in rough environments.

• Aircraft-grade anodized aluminum body for strength and weather resistance.
• 10" braided nylon hose resists kinks and abrasion on the trail.
• Rugged construction suited to repeated, off-road use.

What comes in the kit and what warranty covers it?

The RX4 ships as a ready-to-go kit that includes a padded storage pouch, a 4-way valve tool, and four spare Schrader valve cores so you can maintain valves on the trail. JACO backs the product with a Lifetime Warranty, offering long-term support for owners.

• Padded storage pouch for secure transport and protection.
• 4-way valve tool and 4 spare Schrader cores for on-vehicle repairs.
• Industry-best Lifetime Warranty from JACO Superior Products.

Who is this for? The JACO Lightning RX4 is built for overlanders, trail riders, and anyone who frequently airs tires down for off-road traction or travels on mixed surfaces. It’s ideal if you want faster valve connections, accurate pressure readings, and a robust tool that fits in your recovery or tire kit. Whether you run a daily-driven SUV that sees weekend trails or a dedicated 4x4, the RX4 gives repeatable performance, convenience, and rugged reliability for controlled airing down at the trailhead.
