A 25-30% decrease in tire pressure will yield up to 250% improvement in traction, by increasing the depth and width of the tire on the surface.

Tests have shown a 40% improvement in overcoming obstacles at lower tire pressures, due to the low pressure tire being able to contort over the obstacle. Therefore the drive becomes a less bumpy, much softer ride.

Light Duty (0-10psi) - SCVLD

This deflator has been designed for those who require lower pressure ranges with extreme accuracy. Suitable for competitive Rock Crawlers & Dune Buggies who deflate to as low as 4 - 5 psi with bead locks. 

This model comes preset at 7 psi and has an adjustment of 2 psi per half turn and 4 psi per full turn of the adjustment cap. It also only requires 2 psi above its preset pressure to start automatically, but can be manually started by lifting the pin as little as 1 psi above the preset pressure.

Standard (6-30psi) - SCV5

This deflator has been designed to suit most 4WD deflation needs. Suitable for beach or bush pressures it comes preset at 18psi and is accurate to within 0.25psi.

It has an adjustment of 3psi per half turn and 6psi per full turn of the adjustment cap. Requiring 7 psi above its preset pressure to start automatically, they can be started manually by lifting the pin at as little as 2 psi above its preset pressure.

Heavy Duty (15-55psi) - SCVHD

This deflator is designed to deflate to and from higher pressures. It is also accurate to within 0.25psi. Designed for use in the light to heavy trucking industry, it is also suitable for agricultural and farming equipment.

This model comes preset at 35psi and has an adjustment of 4psi per half turn and 8psi per full turn of the adjustment cap. It requires 8psi above its preset pressure to start automatically or can be manually started by lifting the pin at as little as 2 psi above its preset pressure.

Camper Trailer Pack (4 at 6-30psi & 2 at 15-55psi) - SCV5HD

This unique set comes with 4 Standard deflators and 2 Heavy Duty deflators. Designed to suit those who tow camper trailers and vans off road and on the beach. While your 4WD tires are deflated to your preferred pressure, the trailer would normally deflate to different pressures based on the weight of the trailer/van.

This set allows you to deflate your 4WD and trailer at the same time without having to adjust your 4WD deflators to deflate your trailer/van. Your 4 Standard deflators are preset at 18psi and the 2 Heavy Duty deflators are preset at 22psi.
