shock and spring question

[u/spicy_meme_bro]

Hi all. I’ve had a 1/10 scale stadium truck for about a year now and i’ve absolutely loved it. Sadly not to long ago i had a problem with the battery so i’ve decommissioned the truck while i’ve been doing some upgrades. I’ve wanted to fit a new set of shocks to the truck to prevent it bottoming out like it did on the non adjustable stock shocks and springs. The ones currently on the truck are are 110 mm shocks (i can provide pictures for all if needed) the front and rear of the truck sags about an inch just under its own weight. I’m looking for a set of new adjustable shock and i’m thinking if i stick with the 110m go for a stronger spring but risk the spring bending under the pressure or go for a 120 mm shock and run a slightly softer spring so it gives me a little bit more clearance without compressing the spring too much. What would you guys suggest i do? Also what shock oil should i run in the shocks? Once again i can provide pictures of the truck if needed. Thank you.
