Yep that KP kit looked pretty nice as I recall. I also really liked the Airride triangulated 4-link but didn't like the price much...

 

I'll let ya know how this rides in couple weeks

 

I was looking at the AirBar but did not want to c-notch the frame so I also looked at the Air4Link: http://www.ridetech.com/productinfo/...ce=%24749%2E00

 

from what ive heard is the KP kit the bars arent as beefy and easier to bend under HiHP, I opted with Suicide Doors, but AirRideTech are just as beefy.

 

The KP components bars are pretty small. I think a 4 link should ride good as long as your springs are the correct rate.

 

here's my four link. its custom with bits and pieces from different places. i got the art panhard bar setup because i like carving turns and i wanted something beefy.

as for towing. i help my buddy move a fridge, sofa, sectional and a large tv. all in the back of my truck and in a medium sized trailer with no problems. it rode fantastic all the way down to l.a.
