gears
+1 on the hot bodies gears. I use them in my jammin and they are hardened steel and last forever. Also, if you want to convert your X1 CRT to truggy gearing, the hot bodies lightning stadium diffs and pinions will bolt right into the jammin. You also have to change the center diff gear to the hot bodies 50t and the hot bodies entire center diff will fit. If you have any questions on what it takes to convert it over to the truggy gearing, pm me and I will make a list of part #s and send them to you.
