So i have the basic 2017 SXT. Im interested in changing out my rear differential gears to the ones for an SXT Plus. I want that little extra kick from the line without doing a ton of upgrades that i cant afford right now. Going from the 2.62 to the 3.09. Is it just a simple swap of the gears or will i need to change out the entire case or get a special tune to make it compatible? Thanks for any advice!
