Always check brake-line clearance. Check front and rear brake lines at full droop and fully-articulated. We staged this photo; in reality, we were okay with the stock brake lines at our lift height, but if they were any higher, or if this was a four-cylinder Jeep, we would have had to use brake line drop brackets or extended brake lines. It's better to check the brake lines during and immediately after the install to avoid possibly stretching them out and losing braking capability. If you go with extended brake lines, make sure they stay away from all moving parts (shocks, springs, and especially tires). You can use a small spring or bungee cord to keep them safe.
