I’m pretty sure my Jeep is on stock leafs and springs but on 31s.. for a kind of budget lift and wheel set up no more than 4.5 in and 33s what would y’all recommend

At 4.5" lift you will need shocks , a SYE kit or a transfer case drop , a new adjustable track bar and springs , longer brake lines . adjustable front control arms I think that's about it .

Do you recommend any companies?

Do you want it in kit form or do you want to get it part by part ?
