    Axle shafts

    I've noticed on Slayer/Revo the male end is outboard while on the Slash they are inboard. Why do they do this? I would think the male end outboard would be best at keeping fine dirt/dust out of the splines.

    I don't know why they do it, but I've run mine both ways on my Slash and there's
    no noticeable difference. I run on a dusty track and have to clean em regularly.

    I'm thinking of swapping them around on my 2wd slash just to try. After looking closely I noticed the splines are very fine unlike the slayer/revos. I had some Slayer shafts that were beat to heck. I have revo boots to put on the Slayers new shafts.

    I've wondered the same. My Slash's shafts are installed the same way as my Revo.

    Between the coarse spline & the less depth of engagement (compared to how a Revo is set up), I have worn out 2 sets of axles on my Slayer pro. My cure was to buy Revo axles & cut them down to allow 1/4" of clearance from bottoming out in the female end with the suspension level. Gives you MUCH more spline engagement to spread/carry the load, less axle shaft wobble/runout & shaft boots too! Reducing the axle wobble at the splines made the axle shaft u-joints last longer, also. You can do the same thing to the fr. & rear driveshafts. Since they don't need to telescope, I set them up at 1/8" clearance. Anywhere you can spread the load & decrease potential vibration, you will reduce power loss - another plus.

    Thanks, I noticed through the range of travel there is very little telescoping going on. I can't believe how much the male (splined) portion of the Slayer shaft is exposed. Now I wish I would have kept all the Revo parts when I converted it to a Slayer.
