    When it is said that exhaust needs to be rerouted, to what extent does this need to be done.


    • The factory exhaust must be modified / rerouted to have adequate clearance on all fixed and moving components, with any long arm lift kit or long arm upgrade like the Rough Country Long Arm Upgrade Kit. The extent of modification can vary based on your current exhaust step up.

      Great Product!

      I was looking for something to make my weekend warrior a ride a bit better both on and off road. I looked at a lot of long arm upgrade kits but didnt want to go with a full kit money wise. This kit met all expectations and went on very easily once the stupid skid plate came off. Would definitely recommend to a friend! Also, product came quick and safely with Free Shipping! Cant beat that.

      Best modification I have done to my jeep by far!!!!

      My jeep has a 4 inch lift with 33s. Originally it had short arm control arms. These started to bend and the bushings would wear out very quickly. I decided to upgrade to long arms and in doing so, my jeep is way better off-road and onroad! I am very pleased with the product and would defiantly recommend to a friend!
