Buying Guide
What to consider when selecting an engine air compressor conversion kit
- Application type: Are you upgrading an automotive A/C compressor, upgrading a tractor’s air system, or adding onboard air for suspension? Choose a kit tailored to your primary use.
- Compatibility: Check engine model, existing compressor type, and mounting compatibility. York-to-Sanden and Nippondenso-style retrofits are common but require precise alignment.
- Air pressure targets: For suspension or bags, ensure the system can reach and regulate up to the required PSI. Onboard systems commonly target 100 PSI, with rapid inflation capabilities.
- Control options: In-cab control versus remote or wireless control affects ease of use, especially while driving.
- Leaktightness and fittings: Look for pre-sealed connections and included Teflon or sealants to minimize leaks during conversions.
- Installation complexity: Some kits are near-direct replacements; others require additional brackets or wiring harnesses. Assess your skill level or plan for professional installation.
- Warranty and support: Consider brands with documented support for parts and troubleshooting in case of integration issues.
