Exhaust Clearance

You may or may not need to make modifications to the exhaust downtube for clearance depending on the model year and engine type. The downtube on our '99 4.0L had been modified in the past to clear our old long arm brackets so we dodged that bullet this time around, but you should be aware exhaust mods may be a requirement. With the brackets mounted to the frame, the lower control arms can be installed.
