Breaking down on the side of the road is the last thing you want when you’re off on a 4WD adventure. Even if your 4WD is brand new, the harder you push it, the harder the engine or your battery management system has to work to keep up. With REDARC’s 52mm gauges, you can track how your vehicle is doing at any given moment and avoid being stranded with an overheated or run-down engine. learn more

Temperature & oil pressure gauges

When it comes to keeping your off-road vehicle in tip top shape, oil pressure and temperature gauges are must haves. With an oil pressure gauge, you can ensure that the correct pressure is maintained in your vehicle and that your car bearings are well lubricated. This is particularly crucial when you're travelling at continuous high speeds and towing heavy loads. Similarly, a temperature gauge can be used to monitor both the temperature and water (coolant) in your vehicle's engine. If the oil in your engine is subjected to excessive temperatures, it can significantly affect the lubrication that keeps the metal parts from touching - lubrication that your vehicle needs to prevent major engine damage. All of this ensures the longevity of your vehicle!

If you've recently added a dc to dc battery charger or battery management system to your 4WD, caravan or camper (or plan to), a voltage gauge is the perfect way to monitor everything. Not only do they enable you to track the charging performance of your battery system, but they act as an early warning system so you can fix any issues instantly.

Boost gauges

Have a diesel turbocharged vehicle? An exhaust gas temperature (EGT) and boost gauge is exactly what you need. Monitoring the EGT in your vehicle is key to preventing engine or turbocharger damage - especially if your vehicle is pulling a heavy load, climbing or running at continuous high speeds.

We also have a great selection of mounts, sensors and accessories to help you get the most out of REDARC's gauges. Don’t forget to check out the REDARC Tow-Pro range or our selection of battery chargers either! Take your vehicle to the next level with REDARC's range of 52mm gauges and keep everything in perfect working order for many years to come.
