Would have been more complimentary to utilize 1/4 Eliptical for added flex in the rear than a very nice looking boomerang, the boomerang gives me a good idea for my new rear ones that i'll be building...
I bet that thing sees a lot of trail use as well, 35" krawlers with a stock D35... Tisk tisk!!
Somone at our Jeep jam 2005 ran the D35 with 35" krawlers and he blew a c'clip.. go figure... but he had it up and runnin again for day two so props to him.
