Which leaf springs to use?

I bought mine from Summit at the end of last year. Mopar part numbers and Made In Mexico stamped on them. Luckily I like Mexicans so it doesn’t bother me.

I have a brand new set of these but was debating on selling and purchasing a set of stock 340 springs. How do they ride and do they sit much higher than stock?
