cutting rear coils? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

chopper john · 12-31-2009, 04:21 AM

i know alot of people cut the fornt coils , its cost efective . but my question is has anyone ever cut the rear coils and remade the pig tales? i want to be about tree inches off the ground.

*2tons of fun* · 12-31-2009, 04:27 AM

lowering blocks.

chopper john · 12-31-2009, 04:36 AM

i need it 3 inch up off the ground. i already have blocks

kiknrocks · 12-31-2009, 04:43 AM

I cut my coils in the rear. You dont have to re-do the pigtail just cut the top part off the coil as much as u want (if i remember rite 1 coil = 2 inches)dont qoute me on that, then just rebolt the bottom pigtail . when you lower the truck back down, the frame will sit on the cut end of the coils. This is what i did for now and it worked awesome. Make sure you completely cut of the rear bump stops w/the medal mount that the bump sits on or your truck will bounce like crazy.Hope this helps, good luck

AAAAACKCKKCKK!!!! seriously!!!!

chopper john · 12-31-2009, 04:50 AM

that really worked? i dont know if i really trust that very much . i know there is peopel that will cut and recoil to whatever you want . i knew an old man that used to do it for a friend of mine but he has passed .

chopper john · 12-31-2009, 04:53 AM

if i cant find anyone then i will think about it . thanks for the info. kiknrocks

chopper john · 12-31-2009, 05:59 AM

anyone else?

WHAMMY'DWONDER · 12-31-2009, 08:25 AM

I did the same, cut off the top of the spring and when you let it down, it rests against the bottom of the frame. The bottom of the spring is still bolted to the trailing arm and ive never had any problems since I did it 6 months ago.

63 & 64 Bowties · 12-31-2009, 09:01 AM

I can't imagine any way you could "make" pigtails without heating the coil. And, you don't want heat on them. Why not go to a junk yard and get used Jeep springs? They're cheap and work well. And, a whole lot safer than no pigtail.

70 Suburban · 12-31-2009, 10:55 AM

For the unknowing.. What jeep coils work.. (maybe we can save him the trouble of damiging his springs.)

**ChiefRocka** · 12-31-2009, 11:17 AM

I also cut one end off. Once bolted in the trailing arm correctly, it will not go anywhere.

Just make sure you position the cut end centered in the frame.

You can, using heat, re-shape the coil end into a pigtail....I have done that many times as well in the 'old days'.

Obviously, lowered springs, or Jeepers are the way to go (I have to throw this in to make everyone happy)

Suspensions...it's what I do

rain_man · 12-31-2009, 11:53 AM

use jeep springs
im prety sure any 97-06 cj rear springs will work

Cherokee (I haven't seen Grand Cherokee done, so I'm not sure of those)
Or, 70's Chevelle springs work too. That's what I used in my 63

chopper john · 12-31-2009, 03:48 PM

does anyone have pics with jeep sprins on them. i wanna see how low it sits . cause i want it to sit like whammydwonders truck. there used to be an old man that used to cut them and remake the ends to whatever height you wanted.

62gmc910 · 12-31-2009, 04:14 PM

You can cut them and reshape the pig tails but you change the spring rate making for a harsher ride
The other issue of just spirng height lowering is the trailing arm geometry
A combination of the tested jeep springs and lowering blocks should get you where you want to be The other Point everybody misses is the panhard bar
It should be remounted to be horizonal at ride height and should be as long as possible and if you are smart adjustable

WHAMMY'DWONDER · 12-31-2009, 04:28 PM

MY truck has the jeep springs that are CUT in the pic. above. They werent low enough stock (stock jeep springs)only got it 4 inches or so lower. and I wanted hammered! by the way, the truck rides soooo amazing with the jeep springs, even cut people that ride in it cant even believe it. Never have had any problems with the cut springs moving around or making funny noises or anything either. oh and I did cut the the springs and heat up an end to make it a pig tail on both ends but it colapsed where I pig tailed it so just cut now, and no problems. jeep springs were outa 01' grand cherokee rear with a v8.

chopper john · 12-31-2009, 04:44 PM

Well i put a 96 caprice rearend so i Have to redo the pan hard bar , as long as posible . But i want the hight first then set pinion angle , last adjustable pan hard bar.

chopper john · 12-31-2009, 06:55 PM

well i guess im gonna cut mine , they are off a g body car . but at the end that sits on the forame ill weld in a piece of pipe to slide it into so it wont fall out . just to secure a little bit

If it's bolted to the truck arm like it's supposed to be, it's not going anywhere.

kiknrocks · 12-31-2009, 07:51 PM

well im sure glad you guys put in your 2cents cuz i know i wasnt the only one that lowered my truck that way. Thanks

smokinjoker252 · 01-01-2010, 12:49 AM

rear springs out of a mid to late '80's 325is BMW will give you about 3-4 inches and a great ride. They are coiled tight at each end so a small cut of the pigtail with a sawzall is needed. This allows the stock cup to be used in holding them in place. I got mine for free when my buddy lowered his BMW

chopper john · 01-27-2010, 02:26 AM

this is how it sits now with the rear coils cut . thanks alot guys it rides beautiful. i used a set of g body springs.
