Hey all. After getting nearly ten years of great treatment from a 2016 Express 5.7, I just purchased this 2023 Big Horn 5.7 Night Edition. Now I am looking for suggestions and ideas on what I should do to it. Specific things like oh, the '23 5.7 needs oil changes every 5-7k, not 8-10k like suggested and only use the Mopar filter or change out the cabin filter every other oil change or make sure to do manual software upgrades regularly. Stuff like that. What general preventive maintenance should I be aware of and do? Paint protection, undercarriage coating, seat cover protection? What modifications are a good idea to improve the ride, transmission shifting, engine efficiency, etc.? Just the topics and I will research it here from there if you do not want to go into the full details.
My first change will be tires. I am not a fan of the Kumho A/T tires it came with and will be switching to Highway all season. Strongly leaning towards the Michelin Defender LTX M/S 2. Only question is stock 275/55-20 or go up to 275/60-20? I just like the 33" look. I know the speedo will be off 1 mph at 30mph and 2 mph at 60. I will get that recalibrated at the dealer.
Thanks,
LNL
