y do you notch the rear when you drop a truck? what is a c notch? are there different kinds of notches??? sorry i have always wonder this i sound like a newbie lol... thanks for answers...

hotrodhomi · 03-31-2011, 04:30 PM

A c notch is a notch cut into the frame and reinforced to allow the rear end more clearance before it hits the frame. There are also step notches that basically replaces a section of frame to allow even more clearance. These are used for vehicles with extreme drops.

i see. thanks that cleared up a bunch of things lol. now for a good question. i have and 83 shortbed im looking into dropping whats the farthest i can drop it before i have to c notch the frame?

hotrodhomi · 04-15-2011, 12:05 AM

that would depend on if you plan on carrying anything in the bed or your expectations of bottoming out. I would notch it if you drop it 4" or more.

'87shorty · 04-15-2011, 12:31 AM

hmmm i dont really carry anthing in the bed if anything every now and then maybe a motor but otherwise nothing. i was thinking about a 5 inch flip kit with shock extenders. how hard is it to install a c-notch

how much was your drop bro?

'87shorty · 04-15-2011, 01:01 AM

do you really think i need to cnotch if im only doing a 5 inch drop?

flamingbig10 · 04-15-2011, 01:10 AM

the above drop was around a 4-9 drop djm 3" drop spindles, 2 djm drop coils rear beltec flip kit, bltec 2" drop shackles, and removed 3" leafs out of 6 leaf spring pack, but that drop didn't last very long I switch the coils to 3" ground force drop which lowered the front about 2 more inches, and added the leafs to the pack for around a 6-8

no just cut the 4 rivets off the factory bump stop above the rear axle and get some stubby bump stops

'87shorty · 04-15-2011, 01:43 AM

Agree just remove the bumpstops and bracket and you'll have plenty of travel, this is my 83 with a flip kit and no C notch and she hasn't bottomed yet, except when I carried a load of rocks and the axles were on the frame

Pops, I'm interested in those bump stops you posted. However, the listing has black stops pictured but to the right it says "red".

babyJay · 04-15-2011, 07:51 PM

ah, never mind. here they are in black...ordered a pair.
