Slash 4x4 hingepins

Got a new package in the mail to fix one of the annoying things about the Slash.  The outside hinge pins on the arms tend to unscrew themselves after 10 minutes of running, so I got some STRC captured pins to fix this problem.  Part number ST3640-RO.

They’re meant for the Slash 2WD rear arms, but those are the same on the Slash 4x4, so they fit.  Now, on my Slash 4x4, it’s only the left arm hingepins that unscrew themselves, and with some minor modification you can use them on the front arm in addition to the rear.

Drill a hole through the castor block, and it should bolt right on.

The package didn’t come with nuts, but they are standard 5.5mm locknuts
you should be able to pick up at your local hobby store or online.  I had some spares.

Don’t overtighten the nut down on the front, just enough to barely touch the castor block without causing any binding or additional pressure.  You want the block to rotate freely in the arm.
