Intercomp Racing shock pressure gauges utilize a pressure range of 0-300 psi. These gauges are perfect for race cars, motorcycles, snowmobiles, and ATVs. Plus, they'll work on any gas-filled shock with a Schrader valve, or needle-style gas chambers with the use of an adapter. The analog gauges feature a liquid-filled gauge face. Their pressure readings are measured in 10 psi or 1 BAR increments. The digital gauges feature a digital display and pressure readings in psi, BAR, kg, and cm2. Their measurements are in 0.5 increments and they arrive with your needle adapter.
