So, i run the Durango dex410v3. I must say it is a plush kit and handles like no other. Up until i drove a friends b44.2. Huge difference in the car. First off, the b44.2 is much lighter (Rango is a tank compared to b44.2) and combined with the bb shocks...extremely plush. The overall layout under the hood makes tuning and replacement easy. The carbon chassis and top plate make the car extremely stiff...the Durango has way too much flex IMHO. Im sure there are many other differences to the Durango but i must say, the B44.2 has me wanting to sell my Durango.
