I put the gear diff in and omg....smooth smooth smooth. Just put some black grease in and away we went. A relation was awesome. No push. Of course with battery pushed all the way up. Stock front springs. Losi white in rear. 30 /25 shock oil. 23 mm ride height. Set slipper. Easy peasy. No maint for awhile.
Thing jumps like a dream. On rough long straight it just kept pulling and stayed planted. Traction for days.
