I have done about 20 to 25 c notch kits on full size and mini trucks over the years that i have been a mechanic and have not seen any problems. I think too many people look too deep into things and start to think the worst. I will be c notching when I end up with my DJM kit.

My mind is basically made up. Its my truck - I own it - I like the look of the DJM drop best - and hopefully with the modifications to the suspension (QA1, Stock Height Coils and Sways) the ride will be no worse than the SOS drop.

As soon as I can get some new ball joints pressed into the control arms, I'll be taking a day off work to knock this out. :rockon:

can you do a fea with the notches but add 1/4" plate to the top of the frame as well so se we can see how that changes things over just the notch and boxing the frame

Theres people on here that have the notch and still tow big boats and I know blastap pulls his rock climber on a trailer behind his and never had an issue. Didnt he also haul somebodies Xrunner back from the track during TexFest after blowing out a clutch.
I think that if it can handle doing those chores its sould be fine.

No notch, no bumpstop.

Had Beefed box my frame on the inside, and welded more plate on the outside of the frame too.
Welded the plate into the holes where the bumpstop was originally.

Boxed the inside of the frame.

I'm going to leave this photo here, many have seen this photo in different frame/djm threads. The truck held up great through my 600 mile journey, had plenty of go/slow down but the taking off was a bitch due to the light flywheel/stg 3 clutch.

I have helper airbags to level it out, without them hauling ANYTHING is a struggle.

Real siked on this thread. Glad to see someone looked into the structuring of the notch kits. Although its debatable, I think notching the frame is a poor decision in regards to voiding the warrantee and depending on some guy to weld the kit on for you (unlessmu can do it or got a good welder guy).
Drops look good but having the function of a pickup truck out weighs the aesthetic value IMO. :top:

DJM notch is not - and should not be welded. Most guys with X-Runners don't haul anything but ass. :laugh:

ok, i think this should be a sticky FOR SURE! but i heard while also, the design of the notch is a big factor to how strong or weak it is, also just installing it and like K2 said, its the heating that weakens the frame! i also heard of some guys, throwing dry ice on the frame to help keep temp down!
