Nice job Birdman. This has been a weak point for sure. We have been running a gusset version for the last year. Recently we have added a boxed double shear arrangement after losing a couple of pins.

The boxed double shear also converts the setup from a pin to a bolt which should be stronger.

If you have been hammering hard enough to be checking for tweaked knuckles take the time to look at the pins. On one of ours it showed signs of having been bent, which may have occurred before it snapped.

Another issue for us has been the lower ball joint. I have bent two this year. Take a look at those as well.

Here are some shots of our current setup as well as the broken pins.

I agree that a fully fabricated version may be a good future step.

Nice write up Bird. Here's what a pair of bent knuckles makes your alignment look like (last weekend at TRRR)




Driver's side tire was just a few millimeters from rubbing on the UCA. Was able to drive it home, but destroyed both front tires.





Definitely time for the upgrade.

Sold me.

Tire and wheel weight play a large role in this bent knuckle problem. The truck is designed for xx tire weight and xx wheel weight then someone decides to change to a different offset wheel, heavier tire and wheel the stresses added are quite high on all the rest of the parts especially the knuckle, the main part that holds all the weight, and keep the upper and lower suspension together.

$750 on SDHQ's website. Is that a pair or per side? What would a set of factory knuckless cost?

I think one of mine is tweeaked.

Well Done Bird. Thanks for the info.

That's for the pair. Not bad since the factory knuckles themselves are a couple bills each.

I think it's time for Camburg to come up with something badass for the Raptor community.

I agree, Sure would be nice if they come up with a full suspension package specific to teh Raptor...
