FAQ
Q: Will this fit my 2018 Ram ProMaster 1500 cargo van?
A: Yes. The SSR-313-54 is designed for all 2014-2020 Ram ProMaster 1500 models, including cargo vans, passenger vans, and chassis cabs.
Q: Do I need to drill holes for installation?
A: No. This is a bolt-on kit that uses existing frame holes. No drilling or welding required.
Q: What PSI should I run for daily driving?
A: For unloaded daily driving, maintain 5-10 PSI minimum to keep the bellows shaped properly. Increase to 50-80 PSI for heavy loads.
Q: Can I install this myself?
A: Yes. Average DIY installation time is 2-3 hours with basic hand tools. Professional installation is also available.
Q: Will this affect my unloaded ride quality?
A: When set to minimum pressure (5 PSI), ride quality is nearly identical to stock. The air springs only engage when you add pressure for heavy loads.
