can someone tell me how wide 521 rear axles are (outer face of drum to outer face of drum,where the wheels mount). I looked around real quick ..couldn't find anything-sorry if this sounds like a dumb question,but thanks for any info.
i jsut got rid of mine this past saturday or id go measure mine for you
AiredOut is the guy to talk to he is on here all the time and has a 521 at his house that he can measure for you. Just send him a pm.
i don't know the exact measurment but i measured one a few weeks ago and its roughly 3" narrower from the axle flange to flange, as oppossed to my hardbody
