shock question f350

i have an 08 f350 with the 6.4 powerstroke and i plan to upgrade to some rancho shocks. the truck has a 3 inch front lift and a 1 inch rear lift to level it out and it has 35’s on it. i plan on 37’s next year but not sure witch type of rancho shock to buy theres a few different options. theres the RS5000, RS7000, and 9000XL.

imput? opinions?

Ummm…

I’m going to assume this is a SRW? What do you do with the truck should answer your question on what shock to use. Is this a brodozer or do you actually use the thing?

I personally like PRO COMP, but Racho are good also. If you are just pounding the pavement the RS5000 will be all you need
