AllPro Expo spring install

During the install of my new allpro expo leaf springs I ran into a few issues.

It seems that I didnt get the correct springs, the eye to eye distance seems to be about 2 inches too long. The centering pin also seems like its about 2 inches further back than where the stock location is.

I took both stock springs out and moved the axle around to get everything to fit but not it look like the strike pads for the bump stops are too far forward. This made the parking brake cable seem way too tight as well so I took off the forward bracket which mounts to the frame.

Anyone else have any problems doing their spring swap?

 

Pretty sure there's a reason why all poo isnt an approved vendor here on TW any more.....

 

Verify part numbers from your order invoice and what’s on the stickers on the springs and check against what people posted here.
That doesn’t look right

 

Yeah everything PN wise seems consistent with what others have as well as what I ordered.

 

It almost seems like I need longer shackles to make them fit right?

Also, when I bolted up the stock shackle there was about .200" lateral play between the poly bushings and the inside the the shackle?

 

And it’s not installed error? Return them then. Might be just another reason why allpro sucks

 

If it helps, I measured my springs center eye to center eye, unmounted, with a regular tape measure and roughly got 54.5".

I'm watching this thread because I just got a used set and will attempt to install at some point.

From what I've read having to remove the parking brake retainer isn't unusual.

 

Thanks Ill double check mine later and compare to stock as well.

 

Good luck O.P.

 

Assuming I can return them what are peoples preferences for something in the same performance range?

 

Can't tell from the pics, usually the stamped p/n end is installed closest to the rear and during install, it's beneficial that the installed side is at full droop with the floor jack on the opposite axle side to make adjustments.

 

Yeah PNs are towards the back closer to the shackle. I would go full droop but since the leafs pulled the axle back ~2in it makes the parking brake cable too tight for comfort..

 

OME HDs. Might even be cheaper too.

 

The axle will move back as it compresses. All pro says Eyelet-to-Eyelet Length (Free) is 54-3/8″. I haven't had any issues with mine so far after 5k miles, knock on wood.

I can't tell from the pictures how you are trying to bolt it up. Installing in the right order makes all the difference.
Both E brake brackets come off first so you don't tear the cables out when you drop the axle.
Then you work 1 side at a time. Take one side out completely. New spring goes in place with the shackle attached to the spring. Front bolt goes in first, stays loose. Rear shackle is next, pry bar helps. Then you line up the axle and put on ubolts. Snug it down but not torqued. Repeat other side, make sure its lined up and torque it all down. Assess you ebrake clamps and decide what needs to stay or go.

 

Thanks, just curious my leaf packs don't have a threaded hole on a bracket to remount the ebrake cable, did you leave the chassis bracket on or off. I took the chassis one off and it seems too exposed and could get caught or hung up if its left loose.
Also the width of the spring seems a bit narrow compared to the shackle, am I missing something else like what what UCAs have on either side of the bushing?

 

I have AP expo pack on my 2nd Gen. I ran without the bracket for about 5k miles and the brake cable wore the paint off the spring. I was worried about it damaging the cable so I just drilled and tapped the leaf spring bracket to take the original Oem bolt for the bracket.

 

I cut the Ebrake bracket off when when I did an AAL. Later went with 3" 10 leaf pack. I carry weight, so I later went to #400 Expo leaf pack

You have to suck those flanges tight against the leaf. That's what nuts and bolts are for. Don't over think it. Yes you do have to use that rear shackle. AP (Montana) installed/swapped my last leaf pack in 90 minutes. Took me twice that on the tarmac at work. Two floor jacks are the secret here. You also need Jack stands that are extra tall.
