Selling the last Slash in my collection as I don’t ever use any more. This is the ultimate edition and has aluminum caster blocks and Traxxas GTR shocks and other upgrades. Has been upgraded to a castle system, I can however put Traxxas stock brushless system on it if it’s preferred. Has upgraded rear axles, RPM A arms front and rear, upgraded RPM bumpers. I am sure I am missing a few things. Message me with questions. Thank you,
