I run 4 shocks from a GS Storm buggy. Use 1/8 scale front shocks - the rear ones make the truck stand up too high. The front shocks are just a tad smaller length wise than stock t-maxx shocks. You only need to run one on every corner of your truck - the buggy shocks are alot more beefy than stock ones. The shafts are nice and thick making it hard as heck to bend them. Ofna buggy shocks are nice too.
