I was just in this pickle a couple months ago. OE springs sagging, wanted to run 33s but thought they'd rub due to sagging. Contemplated heavily between a rough country 2.5" lift, or new stock replacement springs. Read a lot about bad rides on lifts....
I ended up up replacing all springs with oem replacements. I used Michigan spring, but cucvrus has the part no and has surely put those to the test. Expect to have a good 600 bucks in them to do it correctly, new bushings, u bolts and the like. It is not cheaper than the cheap lift, but I am very, very happy with the results. Rides great.
also fwiw, I am running 33x12.50s on the stock wheels. Stance is great, love the look, no rubbing so far at full lock but I don't wheel it. Like you, I just wanted a good ride and something to help me through the Midwest snow. Big plus - still fits in my garage!
