View Full Version : Attn: Blt2Krl and RIverbeast...Chevy Springs
05-27-2003, 06:51 AM
Hey guys, I'm building a '88 Grand Waggy for a friend at the moment and the initial plan was to move the rear axle 1in back. Now he wants me to go 3in back or more so I says ok. Anyways, my question is what year and model springs is it that moves the axle back 3in and are those springs compatible with your shackle flip kit RB? Thanks

On my Chief, I took the four front spring hangers off a Wag and had them welded underneath the outboard mounts on the frame. Then I'll use '93-00 (I think) Chevy Suburban springs to take up the extra length created by relocating the mounts. The rear springs should move the axle back 3" if I remember correctly. Here's a link that should give you some more info. He's got some good pictures on his site.

Well I've already got RBs shackle flip kit so thats why I was wondering if I can go ahead and use that with the Chevy springs. I think RB did exactly what I'm thinking of doing, but not positive.
edit: It said in that link the dude used '93 Suburban 1500 springs...what other years will work just so I don't have to look for just a '93 in the junkyard.

Andrew, I'm using Todds kit with 93 1/2 ton burb springs. Todd is using 3/4 ton burb springs. Not sure on the year. I took the overload spring out. These spring felx like crazy. I mounted Todds kit right underneath each factory hanger. The springs are longer than the factory waggys so the shakle angle is right on...

What about just putting chevy springs on the axle with the axle in it's stock position, cutting off all the hangers, and rewelding them into position on the frame so that they won't move the axle back any?
Am I just stupid, or a glutton for punishment?

Andrew... I am using 3/4T 96 Burb springs with the over-oload removed....
using my kit... mount the front mounts EXACTLY as the directions say to... on the rear shackle mounts.... you can swap the left to right(this gives you more room to the rear of the OEM mount) to get the shackle in the correct position... that is what I did with my burb springs.... the 96 Burb springs moves the axle 4.5" to the rear and FLEXES LIKE CRAZY!!!!
It does throw off the pinion angle a bit since the Burb springs have a centered springpin unlike the FSJ springs which the centerpin is offset tot he front.

Since the QT gas tank is different than the non QT gas tank, we need to move the axle location back to allow clearance. Others want a longer wheelbase for a better departer angle. I wanted both...

I did mine for similar reasons and to get the W/T flares behind the doors....
Gas tank wasn't a problem for me... I run the rear Bronco tank....but moving the axle back did dramtically improve my departure angle and ( not sure yet) may just clear the tank on departure with the 36's.... let's hope...
Lets not forget the driveline angle relief in this as well... 4.5" rearward is alot of angle taken out of the rear shaft.

OK, let's say I do something like this on a waggy, but don't feel like going through the hassle of relocating my axle back. What if I put a chevy axle in the oem place, then relocate the spring mounts to accomodate, since the chevy springs don't offset on the center pin?

Then you have more work to do... the front mounts will have to moved forward and the rear mount will need some attention as well.... more work than that is worth if you ask me.... just keep the FSJ springs and add the GM axle and crack a beer.

hey todd,or paul whats the height from the pinion to the ground,with ya'lls tires?
i know your tires are simular in size! just curious about ground clearance from a 14b to a d44
of course the pig is definatly diffrent in clearance!!!
05-29-2003, 02:41 AM
Sam... I cant give you that measurement as I still have it sitting on 245's right now... 36's still in the garage.... sorry...
Pinion is not the concern though... its the bottom of the pig.... the 14FF is HUGE and you lose about 2" of ground clearance at the base of the pig compared to the D44
I think Paul already shaved his... your somebody did... I remember talking about it... but can't remember who... could have been Scotty....
