Skyjacker radius arm installation issue.

[JMF661]

Hello All,
Trying to finish up the installation of a skyjacker 4 inch lift on my 1994 4x4. I had hung the driver side beam, however the radius arm was “stuck” and would not pivot toward the center of the truck enough to stab it into the new radius arm mount. Upon closer inspection the inside of the radius arm is getting snagged up on a structural component of the beam.
It seams like the easiest solution would be to shave down this raised edge to allow for an appropriate amount of clearance, maybe sacrificing some amount of structural integrity .
Does anyone have any previous experience with this issue, or any thoughts or opinions.

Yup. I took the grinder to the lip you have circled. Everything is fine so far.

I'm soooooooooo jealous of the rust free trucks you folks have...

Ya'll just can't comprehend what we deal with... kiss my big white rusty ass... and have a nice day.

Flapper wheel. Are these arms left right specific? I was reading about a higher clearance arm potential somewhere.

Don't remember who it was

I think they are R/L specific due to caster angles.

They are side specific. No salt use does wonders for old pickup trucks

Looking at the leading edge of the radius arm and looking at the edge of the Ibeam, pretty sure I’m going to follow others advice and smooth the Ibeam down with a flapper wheel. I’ll report back with some results.

So, ended up shaving down the structural protrusion until I was beginning to get into the aluminum diff case. Was able to get everything together and it seemed to cycle just fine, no binding. All chassis and suspension components are locked and torqued. Now I just need to put the hubs back together.

After reassembly of the steering links and hubs, it is obvious that the drop pitman arm doesn’t return the steering assembly to anything near the factory setup. This was expected. Will definitely have to dial back and lengthen the end links to get the steering knuckles even close to facing the same direction.

Did you install a skyjacker 4inch lift? If so, did you use the upper or lower holes for you axel pivot points.
I used the upper holes and it sure looks like I need to switch to the lower.

Which radius arm brackets?

I installed the 6" kit. Used the lower holes.

 

[JMF661]

The skyjacker replacement front pivot points have a lower and upper hole for the Ibeams. I should’ve used the lower points to gain a better camber angle.

Got another question for you! On the rear did you install the new skyjacker leafs, if so did you eliminate the factory block/bump stop?
