Be careful if you use any diff cover with any 39t pulley in these, I ruined two pulleys and a belt doing so. There's insufficient clearance within the bulkhead assembly to allow anything to pass through causing everything to bind if even a tiny stone gets in (which it will if there are any at all on your track). I posted about it on here somewhere.

The old diff covers will not work - you'll need Fredrik's new "upgrade kit" diff covers, 1) because the pulleys are larger and 2) the diff/belt is now running/coming out "on the other side". They are already available - see Fredrik's thread.

@trf14, As for set ups, the suspension set up is basically the same for the old 511 vs. the upgrade kit - go to petitrc.com and look for set ups there.

Would say, be careful to run with 511 at all on tracks with small stones.
I have ruined several pulleys and belts running without covers.
They get stuck between pulley and rear suspension mount.

Short diff covers give some protection, but as I have said before, not sufficient protection on those kind of tracks.

You will need long diff covers to get proper protection on tracks with small stones.

Might do a revised long diff cover for conversion set.

I'd be interested in the long ones again.

My track hasn't changed in 4 years so the stones were always there (very, very small 2mm - 3mm stones).

Never had a problem with your long diff cover, it was awesome.

As soon as I got the upgrade kit and used short covers disaster struck (combination of smaller cover and bigger pulley).

Running without covers now with no immediate issues (because the stones seem to get spit right out again if they're 'ingested') but the the peace of mind would be good because something will eventually get jammed.

Looks like Fabs is getting ready for a 503.
