used lift kit

I’m looking at buying a used JL or JT and I see a lot that have already been modded that I like but I’m leery about used lift kits. I can either find one unmodded around $30k and throw $8k at it or find one around $38k that has a lot more than $8k in mods already done to it. What experience do...

Bought a take off suspension of a 2022 XR Rubicon to put on my JL sport. Had only about 200 miles on it but wasn’t cleaned after it was taken off and sat a bit. The third link/control arm joints developed a bit of surface corrosion. What is safe to use to clean it off and what should I put on it...
