CPV Steering Knuckles - Review

[M0rphin3]

Recently I purchased these knuckles from Ebay, was able to get them both for $18 shipped which to me wasn't a bad deal, even if they turn out to be junk, so I thought I would take a few pics of them and let everyone else decide what they think.

First thing I noticed upon inspecting them was that all the areas where the plastic stock knuckles need shaved to gain steering were not there, so these would increase steering throw without any modification to themselves or the C-Hub. Secondly the bearings fit perfectly, but are not snug enough to cause issues getting them in or out. The turnbuckle screw hole is tapped, this to me was a plus, added stability. After adding the bearings and placing the axle ends in I noticed that they were not centered like the stock knuckles. The knuckles appear to have a (-) camber built into them, which is achieved by changing the angle at which the axle is "mounted".

Now i did "mock" them up on the control arms with the dogbones attached to see how the added steering throw would effect them "popping" out, and at full drop, (without shocks attached) and at full steering throw there were still a few millimeters of space left for the dogbones to ride in before they would pop out, but this cant actually be decided until I put them through the paces.

Looks like a good deal, let us know how they hold up.

They look nice and not a bad price at all.

good review Morphy, +rep for adding this information.

Update:
Got them mounted and was able to run about 3 tanks through the truck, turning radius has increased slightly, did not pop any dogbones out which is the only thing i was worried about considering the added throw, them seem to be holding up ok, but only time will tell..

Morph can we see a shot tires on sitting on tires, wheels turned either all the way left or right?

nice, was gonna ask if anyone have tried those. They fit front and rear right? or front only?

Will do frddy, I actually took a pic of it with the wheels on and turned sitting on the ground, but forgot to upload it and post it.. duhhhhh

Yes these will work on the front and rear, I only did the front since I use the Integy rear carriers that do away with the c-hubs/knuckles/turnbuckles

As requested, here are the photos of the steering throw with the tires on.

Update:
Ok first race this sunday with them, and the first problem was during practice and i did in fact pop a dogbone, quick fix to this was to add a piece of fuel tubing into the diff cups to keep the dogbones pushed out into the axel cups, this was a known issue i thought i might cross due to the increased amount of steering throw. I also decreased the throw on my TX to about 85% just to be safe while racing.
Even though the axels are mount in the knuckles at a - camber angle, i still did not find this enough, so i added the adjustable upper arms i had laying around to get the correct camber i wanted for the track.
Another thing that i noticed was a little bit of play between the cross pin for the hex's and bearing, this causes the axel to slide in/out slightly, but this was quickly solved with a few 8x10x.03 shims i had laying around, this also tightened up the slop in the front end greatly.
All in all i am very please with these and their 18$ price tag.
