Front spring pin and plates
My son and I put on new rough country 3 inch lift springs on his 76 j10 quadratrac yesterday. The springs are on but we have not attached the axle to the springs. We have looked all over trying to get the correct inflation on a few things - I have a few questions.

1. There is a thin plate that was between the axle and the spring, on the driver's side it has the steering stabilizer mount. With these plates in, the locator pins seem too short. Is this normal? Should I try to get longer ones? (The pins are just bout flush with the top of the plates, so won't engage the axle. The pins appear to be the same length as the ones on the old springs.)

2. I am trying to put new bottom plates on that have the sway bar connectors. It seems these would replace my bottom plates, but I have seen pictures / threads where it seems there are 2 bottom plates, like they put the ones with the sway bar mounts on them, then put on plates that appear to be like the ones I currently have. Orhers seem to just have the plates like my new ones, that is, just the plate with the sway bar connectors as the bottom plate. Can anyone enlighten me on this?

Go to napa and buy longer pins and spacers for the pins and replace. The lift is generic and designed to fit many applications hence you may need to make work with your application.

Ok, that's what I would have guessed, but was confused because they seem to be the same as the stock springs- in other words, it doesn't seem the stock spring pins where engaging the axles. Also, I couldn't find anyone else talking about needing longer pins.

Hello: I just finished installing the RC 3inch lift Springs on my 76 Wagon.
I encountered the same thing. I called RC and asked. They said I probably would not need the spacers. So I installed without. I of course kept them handy just in case.
My rig is not driving yet so I cant comment on how it drives.

Ha, I called and they said leave them in, but at the time I did not realize it would make the pins too short, so I didn't discuss that with them. I want to keep them so I can use a steering stabilizer if I want to in the future.

It's a hassle because spring is curved & plate is flat.
Once you start tightening ubolts it'll work/go into perch.

So, you are saying the pin on the rough country springs are long enough once the spring flattens some? I'll have to look when I get back home but it just didn't see like the pins would be long enough; I guess the stock pins worked though... And they seem to be similar length.

Skyjacker sells a longer swaybar connector bar for this. I have a 4" lift and bought the Skyjacker longer swaybar rod.

This is what the steering dampner bolts to on your steering gear in the front;

This is the swaybar connector;

Not sure about the set up you had before you took the old spring off. As for mine
the original had the shim which made that pin flush away. Since I left the shims out, how about you put them back in with the new leafs and we can compare!

76j10build 02-09-2020 01:31 PM

Mine had the shim plates originally, or at least before I got it. It appears shims will make the pin flush, but maybe once the springs are flattened some the pin will be a little higher but it doesn't seem enough. Seems the pins would need to engage the axle, right? Maybe not, seems like they weren't before. My inclination right now is to get longer ones if it doesn't look like the current ones will work.

Are you guys talking about the degree shims to correct your caster? If so, unbolt the spring pack and run the center pin (bolt) through the shim. Like RC did to the springs at the bottom of this pic.

As babywag mentioned, the springs will flatten out once you tighten the ubolts so the plate for the stabilizer should still slip over the center pin and into the hole in the axle.

76j10build 02-09-2020 05:14 PM

The "shims" I am referring to are the plates between the spring pack and axle. On the driver's side the plate has the bolt for the steering stabilizer to attach to. On the passenger side it is just a plate. (Both have 3 holes - 1 for the spring locating pin, and 2 holes on part of the plate that sticks out for a u-bolt to go through).

I guess I will try putting it back together trusting the pin will be long enough once the springs have pressure on them and flatten out a little. My concern is getting them lined up before I put weight on them - there is some twist to them and the axle wants to go to the passenger side (because of the steering linkage?). I'll give it a shot though.

Anyone have any input on the bottom plates that have the sway bar mounts? Are they to be mounted by themselves or with additional bottomed plates?

bkilby 02-09-2020 07:03 PM

I know of the plate for the stabilizer but my rig doesn't have the other plate. On the bottom, I just use the spring plate with the sway bar mount. I don't know what other plates there could be. :huh:

asphaltrockdweller 02-09-2020 07:15 PM

I know what you talking about! (I think?)

Take a look at the picture here;

There should be from the factory in 1976 a plate that rides between the axle and the top of the spring.
Then there is the sway bar end link mount on the bottom of the spring, under that is a cast iron plate that the nuts go under.

76j10build 02-09-2020 07:17 PM

Ok thanks. I assumed that was how it was but was not positive. (I had seen a picture where the bottom plates without the sway bar mount were used over, er, actually under, a plate with a sway bar mount. That may have been a modified situation).
