With 35s you will need to upgrade your axles. The stock axles will not last long with 35s. You will also need to regear, either the axles or tcase or both. I'd recommend a spring over axle lift with 31's or trim the fenders and run 33's.
Popular axle upgrades are Toyota mini truck axles, which are alot stronger and a little wider. Also swapping in the leaf springs from an 87-95 Jeep wrangler, they are not bolt in but are stronger and will make it ride alot better.
