I am new to the jeep world and recently picked up a 2000 TJ. After a thorough look, it looks like my control arms in the rear are shot and all bushings need to be replaced. My jeep has a 4 inch lift on 35 inch tires. My question is, should I look at aftermarket adjustable control arms? What is the benefit of these over stock? My jeep is used for more road driving than off-road, but it definitely is doing some wheeling.
