I don't think it was a have to have but I like the look. I don't have any rubbing issues. If I didn't have the body lift, I would've had to pull the liners back a little.
Just ordered 2.5" level with 1.25 rear block and 1.5" body lift. Going to put on 305/55/20 tires and wheels with 18mm offset. Foresee any issues with this setup?
