C-notch question

[harley]

Planning my disc conversion/lowering project for spring time. I'm only going to do 5" lower rear springs and was wondering what you all thought of those bolt on c-notches that LMC and Classic has.

Do they really work? Would it be better to weld them in?

Besides those, what other parts would be necessary for the rear end to keep things centered?

This is for a '63 SWB, link below. I've not set up a photobucket account yet

...I used a "c"-notch from "brothers" but it does't matter where you get it I cut my frame with a plastma cutter, but a saws-all will work just as well, and bolted it in with the provided grade 8 bolts ,I also welded vearious places on mine for security.
used a "adjustable trac-bar" and 4"drop springs(all available) work time -3 hrs +-.

I thought you didn't need a notch for a 5 inch coil drop..

...you most likely don't. but your suspention will settle aproxx 1/2" -1" once you put it back together,and planning ahead never hurts ether,you may want to go lower later and you will be set up and ready....

I had a bolt in notch in my s-10 and it was strong with just the bolts... It was only a s-10 but im sure yours would be fine... I used a sawzall to cut mine out... Very easy task

You don't need one for a 5" drop? LMC says right in their catalogue that you do

You guys would no better, that's why I asked here

Im pretty sure its says in lmc u "need" a notch for anything 5+, but that also depends on what kinda ride u want, if ur droppin 4 inches and loadin it every once and a while, ur gonna be ridin the bumpstops, so might as well throw it in, lol, according to statements above, it shouldnt take too long...

Maybe I missunderstood their catalogue Anyway, I'll throw one on the list of things to do.

This truck ain't for hauling things, I have a 1 ton dually for that stuff. This truck is just for looking cool

I'm thinking now maybe 6" rear drop would be cool too

This is probably a stupid question But what does the adjustable trac-bar do for you?

[isdeleon]

i got my c-notch from classicperform.com and it fits nicely. i do recomment bolting it because the weld might crack due to the constant deflection of the frame.

I dont have a c notch. but when you haul anything in the back it will ride on the bumo stops.

it allows you to center the rear end between the frame rails.

isdeleon, thanks for the pics. I was assuming the frame was cut completely but it does not appear that way in your pics.

A good rule of thumb with installing the notch is to remove the minimum you think you need, test fit, then remove some more - if required. Also, there have been a few threads on installing notches and several members suggest drilling holes in the corners of the area you plan to remove especially if you don't plan on welding it in. A sharp corner may create a point where a crack could develop in the frame... A round corner will be a lot less prone to this possibility.

That makes good sense, drilling the corners. Thanks.

glad i could help. and there are some c-notches that do require to cut the frame completely but thats only if you want to lay frame. for what you're looking for this would be your best bet. as far as installation goes, classicperform tell you to use the c-notch as a template then cut, but drilling holes on the corners helps a lot. you can also go to http://www.classicperform.com/Instru...DF/6372CNK.pdf for the complete instructions if you'd like.

Perfect. Looks pretty straight forward.

i bought a set of drop rear coils from a buddy, he thought they were 5". dropped my 3/4 ton 8" now im sitting on close to the frame. took the bumpstops out becuase the rear end was touching them. how much were these coils?
