I'm thinking of installing a ati 15% underdrive pulley on my 14 ram hemi sport and advice on this and how can I find what gears I have?

Well, Moe's has them here: https://www.moes-performance.com/ATI_Super_Damper_15_Underive_Pulley_09_up_Ram_5_7_p/ati15ud-4g.htm

You can run your VIN through the Mopar build check tool, or crawl underneath and look at your rear diff, it'll have the gear ratio printed on the barcode. Might have to clean it off to read.
