On the other hand i could tell you....
You need to get 2 packs of the turbo big shocks for the Inferno. And a set of the shock mounts. Look in your manual for the part numbers.
If you want pics of the dual shocks set up go to
http://www.madforce.net and look through the photos section.
Be warned however that the extra shocks also need the super soft (yellow) springs and lighter oil. They also make the truck's handling worse and landing jumps harder. There are many racers who remove the extra shocks when they race for these reasons. They are really only a cosmetic addition...and is it worth it for over $100 expense?
Just my opinion...hope it helps
Cheers,
David
