I searched and couldn't come up with much on the subject. I was just wondering if 421 axles are comparable/similar in strenght to the 406/16 axles. I'm assuming they are the same, only narrower. Any help is appreciated. Thanks
Anybody familiar? My buddy is looking at purchasing a set to throw under a buggy and doesn't want to make the wrong choice. The seller is waiting on him. Thanks guys
From my observations, the 421 axles are from the same family as the 406/416 axles, just narrower. They look almost identical form the outside, so I would guess that the R&P and Portal gears are the same, just different lenght axles. It might be worth confirming the gear ratio, since most of the 421's had a top speed of somewhere around 35-40mph, so the ratio might be too low for the application.
Cheers,
Ben
