2021 vs 2020

[Lives The Dream]

On the Jeep.com website in model comparison 2 things not available for 2020 that are available for 2021:
1. Heavy duty 4wheel ABS with front FNC
2. Non locking fuel cap with discriminator
There is no other reference to them for on the website, does anyone know what they are/have photo?

Is the discriminator required due to the Diesel engine and fuel contamination?

Are the heavy duty brakes larger? What is FNC? I hate acronyms.

I also hate acronyms. As a nurse, the letters BS, can be blood sugar, breath sounds, bowel sounds, or bull shit. I know that the gas cap is non locking, you can buy a locking one, not sure what a discriminator is and same goes for FNC. Looks like the max tow heavy duty brakes are now standard.

Ferritic Nitrocarburizing (FNC) is a process used to reduce corrosion on brake rotors. FNC eliminates “lot rot” by drastically improving the rotors cleanability. Brake pulsation due to corrosion is eliminated when FNC is applied. FNC Brake rotors last longer because of their resistance to wear and corrosion.
