Tuning, Gauges & Electrical

Tuning, Gauges & Electrical covers the electronics that control, monitor and power a diesel truck. Modern diesels rely on sensors and computers for nearly everything, and the right monitor or gauge lets you keep an eye on exhaust gas temperature, boost, fuel pressure and transmission temperature before small problems turn into big ones.

Shop handheld tuners, dash-mounted tuners, performance modules, throttle boosters and tuning switches, plus digital monitors and gauges and gauge pods from Banks, Edge and AEM. On the electrical side, we carry alternators, starters, batteries and cables and sensors, wiring and connectors from Alliant Power, Hella and others.

Use the Year / Make / Model search to filter to parts that fit your truck, or pick a category below. Check your state and local emissions regulations before installing any tuning product, and make sure any tune is matched to the parts on your truck. A monitor is a smart first purchase on any diesel you plan to tow with.
