I'm really liking the additional clearance of these new C-hubs. Probably going to order a couple more sets for some of my other TRX4s.

Did you notice a difference with the new Steering Pull Rod?

Don't know what a "Steering Pull Rod" is, do you mean a Drag Link or Tie Rod?

Mine seemed to improve the turn radius some before I got the longer "Ackerman" drag-link, then it improved a little more when I got one. I am still using the stock servo link, mounted into the stock hole in the knuckle, though. Not sure if that's a gain or loss, or neither ..... or both. I definitely like the set-up. I've got 10 or 12 hours of crawl time on mine now and everything is still rock solid and smooth. They're "all that and a bag of chips".

120g from the manufacturer. I would imagine that is each side. Unsure what stock ones weigh.

Got mine installed and couple things:

1. What are the little aluminum spacers for?
2. I had to go back to stock wheels and tires for now because the steering arm hits my tires on the RC4wd rally wheels.
3. The stock bolts that go in the portal cover are too long and bottom out in the new inner portal covers. I had to source some slightly shorter ones from my drawer O' bolts.
4. When I mounted the shocks to the C-hubs instead of the link mount I had to adjust my panhard bar length to re-center the axle. I used a 55 mm (75mm eye to eye) Traxxas Turnbuckle TRX2445. It just clears under full axle compression. It should meet all you adjustable panhard bar needs.

I set the ride height lower so it made the axle a little bit more off-center than my OCD cares for.

The shocks seem to clear ok to me without a spacer. They are close though.

A specer would work also. Yeah the turnbuckle is adjustable so if I ever change ride height again I can just adjust it again.

The turnbuckle is threaded into the ends so you just turn it either way to lengthen or shorten it.
