Possibly a stupid question lol

Is there any disadvantage to stiffening up the center driveshafts in my krston xl? I just did the rubber thing arrma does with the dogbone cups. Little peice of rubber in the cups that keeps the center driflveshafts from being so sloppy. They no longer have all that play front and back.

Careful with that. Probably no big but there is some space there for chassis flex (I assume).

Ive done that putting little o rings but please make sure you have some back in forth movement don't stiffen them too much

You could use some pieces of foam earplugs to replicate the same thing but will still let the chassis flex since the foam would be less dense than the rubber

Just seemed like a lot.

I like to use a dab of High Heat red gasket silicone. Just squeeze some inside the cup and fill to just below the pin slots. Heat from the diff won't break it down and it remains very soft and flexible. Allow it toò dry overnight before installing the shafts.

Great idea bro. I may employ this in future maintenance.

Here's what I use. There are many different types but this one served me well sealing diff cups, bulkhead/chassis, and even shock caps. Trick is don't apply too much and have just enough that the compression squishes it.
