Fun job
Great product, if your going to do this job yourself buy the extended reach ball joint press to get the old pins out, cheapest option as far as tools go

What a bargain. The only thing that was wrong is the king pins slot was .035 shallow of the depth needed for my NPR.

These suck. By the OEM ones
These bushings and king pins are horrible to get in. By the OEM ones. I actually mushroomed the king pin trying to drive it in.

Great Quality!
We had our repair shop install this kit into our 2014 Isuzu NPR HD. The job was as expected, angry mechanic having to bring out their torches to get the old ones out, but the kit itself was fine. I asked them if the noticed any quality issues or difference between this and the OEM (which looks identical from what I could tell). They did not even know it was not OEM. Saved about 200$ and the kit worked great!

King Pin Kit
Easy to install fits my ford perfect. Needed to get my cattle to sale and my king pin was broke. Ordered this and it was a lifesaver and a payday.
