Jeep Coil Spring Drop
 

Hey guys Im new to yor site and I had been looking through the pages and saw a discution on lowering by using jeep coils in the rear and cutting the coils in the front. So I said what the heck lets do it. Here are a couple of photos of my 65. I cut one full coil plus 3 inches in the front I figured I can allways cut more buts its hard to add.

before and after attached I hope

Re: Jeep Coil Spring Drop
 

I used 98 wrangler springs. Now that I look at the pictures they don’t really do the drop justice it must be the different angle but the lowered the back about 4 inches.

Re: Jeep Coil Spring Drop
 

Thats funny I felt the same when I snaped a few before after pics of my 60.
The jeep springs are a cheep easy swap, but don expect to haul a huge load.
Nice truck and Welcome from Nor Cal !

Re: Jeep Coil Spring Drop
 

What did you pay for the rear springs?

Re: Jeep Coil Spring Drop
 

If you look a`t the 1st Pic you can see all the tire from top of Rim up & in the 2nd Pic it is just Top of Rim, Anyhow it Looks Great................

Re: Jeep Coil Spring Drop
 

did it bolt in or did you have to mod them any

Re: Jeep Coil Spring Drop
 

Thanks for the welcome.
I dont realy put much in the bed. But I do pull a small trailer with my lawn equipment on it. I just have to take it a little easy over the bumps

Re: Jeep Coil Spring Drop
 

I gave $20 for them but Im sure I could have got set for free if I would have put a little effort into it.

Re: Jeep Coil Spring Drop
 

they bolt right in but the spring it self is bit thiner so the hold downs may need a little motification.

Re: Jeep Coil Spring Drop
 

I got them for 5.00 +10.00 shiping off of e bay. look around for a 4wd shop that works on jeeps, chances are they will give them to you.
Oh and mine went in with no mods!

Re: Jeep Coil Spring Drop
 

It looks great. I would like to do this to mine, but I would like a bit more drop in the front. How much did the front drop? Also what do you mean by 1 full coil plus 3 inches? I understand the one full coil, it is the plus 3 inches that is throwing me. Never mind, I figured it out.

Re: Jeep Coil Spring Drop
 

You know I didn’t measure the drop in the front but I would say about 2 inches. I put the rear coils in first and the truck sat lower in the back. After I cut fronts it now sits with a slight rake. I did have to cut some off the stops in the front.

Re: Jeep Coil Spring Drop
 

Nice truck. Looks good with the new drop.

Re: Jeep Coil Spring Drop
 

OK thanks, and welcome to the board from Cookson OK.

Re: Jeep Coil Spring Drop
 

Are you using Jeep springs in the front? Wrangler, Cherokee, grand Cherokee??

I bought a set of front 6cyl cherokee springs and mine goes to the bumps (front). If I put 100lbs of lift it sits at the ride height I want so I think I'll build a spacer. I'm running a LS1/4L80E combo so I would think my front weight should be lighter than a SBC/TH350 combo.

Not in the front just the back I cut the ones in the front.

Re: Jeep Coil Spring Drop
 

drop springs are so cheap and allow you to carry the same load as stock, why use jeep springs? :hmm:

Re: Jeep Coil Spring Drop
 

I'll tell you a few reasons to not use drop springs :)

A long light spring rate is the way to go. It stores more energy for launces. It alows the front to rise rapindly and depending on how the rear is set up (relationship to antisquat) it will help plant the tire harder allowing more seperation in the rear.

Another thing to take in to consideration with a stiff spring is the fact that your tire does not stay with the road as well. A light spring allows your tire to follow bumps better and not throw you out of a corner when a bump is introduced. Vehicles actually handle much better with a lighter spring and stiff sway bar set up. Again allowing the tire to follow the road better. Herb Adams who is a road race / circle track guy talks about this in his book Chassis engineering and Dave Morgan NHRA Chassis vetran also talks about under springing a car.

Also, just because it is a lighter weight spring does not mean you can't carry the same load. If your not itroducing coil bind or smashing down on the bumps, there is no advantage to a stiff spring IMO.

Not to mention a smoother ride.

I Am Using A Set Of Front Springs Out Of A V6 Honda Accord That Are Cut In Half For Rears ,using The Top Half Wich Is The Progressive Side.used The Oe Spring Hold Downs With A Little Mod.truck Launches Hard With A Cad Motor,and Hooks Way Better Than The 5" Lowering Springs That I Had Before!!! Brand New 1/2 Ton In Front Chopped To A Slight Rake, Using A Sway Bar Out Of A 454 C10. Very Nice Ride Now!!!!! Just A Little Insight For Guys Who Are Heavy Hearted Up Front,keep It Light Out Back,{spring Rate}

Re: Jeep Coil Spring Drop
 

Re: Jeep Coil Spring Drop
 

I know the wrangler springs work but what about the cherokee and grand cherokee springs? Also what years of chevelle springs work and how much drop do they give?

Re: Jeep Coil Spring Drop
 

Welcome man...from a little ways up !!!

That's the best looking lawn truck I've seen in a long time !!!!!

The drop looks perfect !!!

Re: Jeep Coil Spring Drop
 

I'm speaking for front springs I tried a set of 6cyl late 80's Cherokee springs. The truck bareley rested on the bumps. Next week I am going to put that spring back in with a 1 inch spacer.I'm guessing it will no longer sit on the bumps and have even more stored energy getting the front in the air fast fr drag racing.

I was on a 4x4 board and was told the V8 Grand Cherokee springs have a little more spring rate in them and would probably take the truck off the bumps with out the spacer.

But from my experience a longer softer spring lifts the front faster. So if the spring is too short, just use a spacer. Just make sure you don't get in to coil bind.

Re: Jeep Coil Spring Drop
 

FREE vs cheap:hmm::rolleyes:
We all know drop springs are relatively cheap, but free is better:).
As a WARNING FYI Here is mine with front springs cut TOO MUCH:o

I cut 2 full coils, then ended up with rubber spacers under the springs and some 1" bumpstops in place of the stock ones. In hindsite 1.5 coils would probably be ok.It rides like crap and bottoms out, but it was FREEEEE and allowed me to save my $ for '32 ford parts:whine:
I got a set of wrangler springs for the rear for free but have not gotten around to installing them yet.:o

Re: Jeep Coil Spring Drop
 

Thanks
I appreciate all of the feedback. My plan is to have good looking but functional truck.

Re: Jeep Coil Spring Drop
 

Were they front or rear Wrangler coil springs?

This thread just helped me out quite a bit with the fact that you say the Jeep coils are the same diameter and bolt in. I can play with the other tech i know and figure a 3" lift for a trailer project i'm working on that started as a mid 60's stepside.

Re: Jeep Coil Spring Drop
 

Not so much that are the same diameter...they pigtail on both ends

Re: Jeep Coil Spring Drop
 

But they should have similar dia to seat in the perch?

I see your sig and dont doubt your input. Guess i gotta get outside and look closely at this.

Thank You Sir.

Re: Jeep Coil Spring Drop
 

Cool man....Welcome to the board BTW....also name is John, not Sir ;)

Someday I'll get my Zuk going...

Later

Re: Jeep Coil Spring Drop
 

I used C.P.P. heavy duty 4in drop in the rear. I give my truck a tow package because it may have to haul one of my old hogs (Harleys for the young folks) one of these days! lol So it needs to haul at least 1k lbs.

Re: Jeep Coil Spring Drop
 

The coils were rear and they are not exactly the sane diameter but they do have pig tails at both ends so they fit in the retaining plates. good luck on your trailer.

Re: Jeep Coil Spring Drop
 

Here is a pic of Heavy Duty rear coils off of my '67 compared to a new set of Jeep TJ springs. The coils are noticeably thinner. Haven't had them completely bolted in yet but they seem to drop the truck about 3 inches during test fitting. Still waiting on a new set of retainers and hardware for final installation. got the springs at a jeep shop for ten bucks apiece.

Re: Jeep Coil Spring Drop
 

The jeep springs I used dropped my 60 over 4". I was pleased for 30 bones.

Re: Jeep Coil Spring Drop
 

I measured 3 inches at the center of the wheelwells. Probably closer to 4 at the bumper.

Re: Jeep Coil Spring Drop
 

Yep 4 inches is about what I got as well. You cant be puting any weavy loads in the back.

Re: Jeep Coil Spring Drop
 

true dat...
I'm a slender 340 lbs. and I could put mine to the bumpstops just by pressing down on the rear bumper, but it rode so damn good. And it was a toy, not a worktruck.
I did have a vintage 7up cooler full of tools in the bed always, and usually at least one other vintage cooler full of beverage, plus 4 lawn chairs etc.
Still rode great.

Im debating whether to stick the jeep coils I have laying here now in my 63 burb, or skip to the slam bags I have.

Hmmm..........

Re: Jeep Coil Spring Drop
 

My gosh guys, I thought that I was the only one who ever thought of this idea using different springs. I put 93 mustang front springs in the front of my 66 and it absolutly SLAMMED it, but I did have only 15inch rims on it. I had to take them out cause the inner fender was on top of the tire! Now I have 20's. My question is, does it hurt the truck if you put different springs in from different cars? Springs have different spring loads right?

Re: Jeep Coil Spring Drop
 

63&64 Bowties, was that stock rear springs from a 70's Chevelle?

Re: Jeep Coil Spring Drop
 

I'm running a $20 craigslist set of Jeep TJ springs with a 2" block and a 3/4" block with longer u bolts on my long bed i haven't driven much since the install so not sure about the ride yet
