the new upper arm i made works good but after you drop the diff the slip joint in the cv bottoms out when the arm goes to full drop, so now i am in the process of modifying the cv. its fun when you extend the travel of one component and another starts to bind. the current kit has stock wheel travel with a much better shock unlimited spring rate capability even dual rate and ride height adjustment. the next kit will have a new upper arm longer shock that will produce more wheel travel and a custom cv. let me know what you guys think any ideas / input thanks
