I was looking under my 4x2 lowered truck and saw that it has an axle flip kit installed. There is no C-notch kit however. The truck currently has about 600 pounds of parts in the bed and it has roughly 1" of clearance before the axle hits a pair of brackets on the frame. MY question, if I were to remove these brackets, and not load the truck as it is now for street use, do I need to install a C-notch kit? I mean, it looks like it would be okay and it has a fairly stiff suspension setup, but I spend my time making trucks taller and have no experience with lowering, the truck is exactly how it was when I rescued it from the barn... aside from scrapping the original cab which had been chopped about 6 inches.

I highly recommend C-notching these if they have a flip kit. The bracket is where the bump stop used to be, you need to remove it. I know people have not notched them, but if the roads are remotely bumpy, it will eventually bottom out.

Okay. That's what I needed to know. It looked like that bracket needed to be removed anyway.

from experiance i havent notched mine and i have a flip kit, i hauled 3 dirtbikes to maine so roughly 250 miles on not the nicest highways, and thats about 600lbs and a kid in my passenger seat, and it did fine with no bottoming out, its not a necessity, but if you going to tow, or have alot of weight in the back part of the bed, then yes i would notch it, that or if you remove your overload spring

I flipped mine without notchin. no big deal there.

i had a flip and hangers, and only about 1" notched out of my frame, still had pretty good clearance, rarely bottomed out unless there were big bumps/drops
