This is a pair of custom Xtra Short Narrow front  suspension arms for traxxas. They are  Even Shorter than the  stock Traxxas 4-Tec front arms (4850).
 
These arms will bolt right on to the front of  Traxxas Jato, Rustler, Slash and Bandit. Check out the Traxxas drag racing forums for more info. Thes are custom so may not be a direct fit for all vehicles.
 
You abviously will need to do some tweeking since these are shorter than stock. You can use the plastic Traxxas axles if you cut them down or some use nitro 4-tec axles.
 
These arms use stock hinge pins or you can find othe 3mm hinge pins that match up if you like.
