lengthening W/B on CJ-5

Ive been thinking about lengtheing the W/B on my CJ-5 only because the way im running now I only have about a 9 in drive shaft. I would like to lengthen it about 6 in in the back. Obviously I'll have to cut the back fenders out but I was wondering if anyone out there has done this?, pictures along the way, how long it took, what you needed to do it, or any other helpful information that I might need along the way

Re: lengthening W/B on CJ-5

1. I'm confused.
2. You want to lengthen the frame/body because of driveshaft vibrations?
3. Wouldn't it be less expensive to re-configure the driveshaft?

Re: lengthening W/B on CJ-5

Well no thats not the only reason. Right now I know Im going to be poping drive shafts like there is no tomorrow, because of the angle and shortness of the drive shaft. When I say 9 inches, im being very generous.

Re: lengthening W/B on CJ-5

Do you want to stay with leafs, or go to a link setup and coils, 1/4 elliptical, or coilovers?
How much fab work do you want to do?
You can gain a few inches with different length springs, springs with offset pins, moving hangers or other smaller items. Or you can go to a link set-up and move the axle back as far as you need to. I have done both 1/4 elliptical and coils setups on CJ5's and move the rear back up to 10" on. I have posted pics a few days ago showing the rear of it.

Re: lengthening W/B on CJ-5

I was kind of going to just stay with the same setup I have now and thats leaf springs and just moving the spring hangers back. What was the name of the post you did, so I can see some pics.

Re: lengthening W/B on CJ-5

This was done going to a 4-link and 1/4 elliptical springs.


You can gain some with your current setup and springs by moving your hangars back, flipping the rear hangers around (so bushing is at the rear), and offset plates for the spring perches, or redrill the hole in the perch and u-bolt plate.

1. Agreed, 9" is a very short driveshaft,
2. However the expense of streching is mind-boggling to me. [img]images/graemlins/thud.gif[/img]
3. I'd still look at another avenue to accomplish the goal.
4. Are you saying that the driveshaft is so short,
5. It will come apart during full articulation,
6. Or are you simply worried about the vibration and U-joint angle?
7. I'd think cardan (or Double Cardan) joints would be the answer,
8. Without the extra expense.

Re: lengthening W/B on CJ-5

I think cv shafts are expensive and stretching is free. But since wheel base and tire size go together, I wouldn't stretch unless you're running bigger than 33s.

Re: lengthening W/B on CJ-5

Maybe he plans on hooking a tow strap on the front and rear. He then ties one strap to a tree and the other to another Jeep. Then he takes a torch and heats the frame so its cherry red and pulls on it. All he's paying for is tow straps (which every good Jeeper should have) and gas.

But back to real life. Unless you've got mad fabrication skills, and even then, stretching it won't be free. You'll need longer brake lines, fuel lines, maybe wiring, materials, labor if you need to pay friends in beer, and then what happens when you screw something up? Its not gonna be anywhere near free.
