Amp Research 18-24 RAM 1500/2500/3500( DIESEL) POWERSTEP XTREME

The description on your AMP Research PowerStep XTreme listing had an internal note at the bottom saying the "20-C" HD year range needs confirmation before publishing, and that note was live for customers to see. I've queued up a cleaned description that removes it and keeps the rest of the copy, including all the fitment details, exactly as it was. Take a look at the change on the product page and publish it when you're happy with it.

That fitment question is still open though: the title says the 2500/3500 HD coverage starts in 2020 but doesn't say where it ends, so it's worth confirming that range with AMP Research or XDP. I left the fitment wording untouched until you have a firm answer.
