Ok, I'm hitting up the junkyards for some rear 'Burb springs so I can finish this SOA and get my shop cleaned out this weekend and ready to get my jeep torn down. My question is what all years should I keep my eyes open for, what is the length eye to eye with no weight on the spring, and will Chevy truck springs work if I can't find a 'Burb? Also, if anyone can get the eye to pin length for both sides with no weight on the spring that would be awesome. TIA

Ok I know I need to be looking for '93-00 burb springs so I'm good there but will '93-00 1500 truck springs work?

I believe they will... the magic number is 63"... I'm not sure how people are getting that measurement... I'm pretty sure the truck springs will work... no idea on eye to eye without weight, sorry

You can use any half ton rear leaf pack from 88 to 98.5. This includes the 2wd versions as well. I can't give you the measurement cause mine are under the rig. You will also have to use the chevy shackle besause the jeep one is not long enough to bolt to the spring without hitting the spring.

These are 96 3/4T Burb springs laid out W/O overloads next to OEM FSJ springs... they are 2-3" longer and the spring pin is centered on the Burb springs.


With the springpin being centered... it relocates the axle 4.5" to the rear...


Sorry I don't have the EXACT measurements... but this should give you an idea

important note

Since the burp springpin is centered... the pinion angle is angle more downward.... make sure you check your angles as I needed to reangle the perch another 4.5 degrees after swapping the springs

On my half to springs, I didn't haver to change the perch angle at all. It was right on. Your 3/4 ton springs look to have more arch than my 1/2 tons, but that would make sense to me..

Thanks guys. I just got back from the junkyard, I got a pair of 1500 Chevy Pickup springs, not sure what year but they are in awesome shape, complete with shackles. They have a centered pin and measure 62.5in eye to eye. They have 3 main leaves and an overload. Not sure if I'm gonna leave that in or not. Any reason why these wouldn't work?

I removed the overload and still sit about 2.5" higher in the rear.... waiting on 2.5" AAL's for the front....

I could just remove another leaf from the burb packs, but I don't want to chance overstressing the springs on flex...as they flex GREAT right now.

RB, have you actually installed the springs yet? did you run into any problems with your kit?

Yeah.... springs are installed.... the only thing you need to do with my kit is swap (left to right) the rear inverted mounts to get the mounts into postion for the longer springs.... worked pretty easily....

Like this...

Ok all this sounds kinda cool, but why are you all doing this. Have I missed something?

I'm doing it for one reason alone. I want to fit a 14 bolt underneath my rig. The gas tank will cause some interference if the axle resides in the stock location. So the burb springs will locate the axle 3-3.5in to the rear and allow the 14 bolt to fit in. The other reason is to extend the wheelbase a bit.

Just a side note here. The 14ff works without any tank interference on the J10. Dennis

will this work without Todd's kit, or do you have to do the shackle inversion? I'd like to get my axle back further, but don't want more height. I like tire clearance by sawzall, but don't want to cut my doors off.

you can do this... but you would need to relocate the rear hangars by cutting them off the frame and moving them back.....

Paul,

Knee is coming along... off the crutches now... back in the garage for light work... kits and stuff... no heavy crap yet as I can't brend past 90 degrees yet....

thanks for asking
