An interesting and informative video from Eaton Detroit Springs


Recommended Posts

I'm glad people are getting something good from the video. Personally, after my experience with cheapo springs, I now see the value in buying quality. I too will be buying a set of (hopefully) Eaton Boss 153lb leaf springs for mine, once the border finally opens and I can go and pick up a set.

I might suggest for anybody interested, sign up for the weekly 1 minute video and other interesting stuff from Eaton Detroit Springs.

I spoke to these guys and they were very helpful a few months ago. I'm going with their standard spring with the 1 inch height option.  I want my vert to be level. I did some measurements based on the Ford's spec's and I'm about 3/4 lower in the back.

For the Ontario members looking for Eaton Detroit Springs springs. Today I called Eaton D S to enquire if there was an Ontario distributor being as the border is closed for at least another month if not longer. I need new springs soon as those crappy Grab-a-Trak are now reversing on themselves. Shipping would be a killer, BUT luckily Eaton do have a distributor in Windsor Ontario. So, if you're in the market for the best replacement springs, leaf or coil, you can contact Glen at JH Restorations; www.jhrstorations.ca or email jhrestoglen@gmail.com The price he quoted me in Can dollars is about the same as if I went over the border to get them myself from either Eaton or NPD. (they're quite close to one another in Canton Mi.) I will need to drive to Windsor to pick them up when they arrive, but that's only a 45 min trip each way, so biggy. By the way, I ordered  ML1823 Boss 351 leaf springs at 152 lbs spring rate as suggested being as I have the 7/8" anti-sway bar. The GTA's are supposed to be 175 lbs spring rate, so we'll see I guess if there is much difference. The ML 1823's will be made to order. Stock ML1481's  (138 lbs) are usually in stock.

For others outside Ontario, I suggest you call 1-313-963-3839 as there might be a distributor in your area.

I have no idea how many, if any, signed up for Eaton Detroit Springs weekly 1 minute video email. I must admit, some are a bit corny, but others contain valuable information when we are installing or do other spring and suspension work. Here is this weeks 1 minute video on correctly finishing a spring install.

I watch them all. They are short and instructive.

Well, today I picked up my new Eaton Boss leaf springs. Now I must wait a couple more days to install them, but hopefully before the weekend as the weather is supposed to be nice and I'd like to get the car out for a test drive. Sorry to say, I'm a victim of my own inability to slow down and now getting muscle spasms in my lower back after staining the new pool deck. Very painful at times, makes me walk like an old man!! Hopefully the wife will decide to go shopping or something so I can do the job without getting nattered at. I'll update once the springs are in. It will be interesting to see how the ass end sits compared to it's current level. If it's too low, Eaton make 1" longer shackles for that reason, but that will be next spring before I will get those in. 

Stay tuned folks.

So, today I was able to convince the wife that my back no longer hurts...... much. I decided to finally get those Eaton Boss 351 springs in. Before I started I measured the center wheel arch heights with 14" rims and BFG 245-60-R14 tires. Right side was 25 5/8", Left side was 25 3/8", so a 1/4" lower. As these old springs had been in and out when I did the axle rebuild, it took longer to jack the car up safely than do the job, or at least that's what it seemed like. As per Eaton video, I did one side at a time and only partially tightening the new Eaton U Bolts until under full weight. It all went in very easily, just took my time so as not to f up my back again or I would never hear the end of it if I did!

So once installed and the U bolts torqued to spec, I took the old girl (car that is) out for a quick run around the block. I was very impressed with the ride considering this is a Mach 1 with a 7/8" anti-sway bar and Gas-A-Just shocks. It was firm, but softer than the Grab-A-Track's I took out. A good comparison is a bit hard to give with those GAT's screwed up, but all in all, I'm very happy with the ride. Once I get a few miles on them and all re-torqued, I'll run it hard on my fav curved road and see how it handles. As for the ride height, left  and right side was 26 1/4", so up about 7/8" and it looks way better. I expect it might settle somewhat, but I think for now it's all good.

Any questions?

Edit; So, today I got the car out for a decent drive so I can re-torque every thing. Here's a pic of how it sits now with the Boss 351 springs, which by the way, I really like.

Two things; Although not in a hurry, next spring will be fine, but as others have mentioned, gas shocks are not the best choice on our cars. Eaton also suggest oil damped shocks. So the question is; what do you guys like on a Mach 1? I'm not looking to spend a fortune, so no exotic stuff. I'm thinking Monroe or similar.

Second, here is this weeks 1 minute video from Eaton.

I got my springs done a few weeks ago. I ended up getting the Dayton "Performance handling" springs, and I have to say I really like how the car feels now. Even with the Gas shocks in it(But my last project car was a STI with crap coil overs) I am thrilled with how the rear end of the car is feeling. I think if anything I may just upgrade the OE sway bar, and then head to the front end.

 Ah, so you were able to get the Dayton's you were talking about. Glad they're working well for you. I was not sure about the quality, so that's why I chose Eaton. Besides, as you have read, I could get them almost locally and at about the same cost as if I went to Detroit and picked them up, so a win, win for me.

Adding a 7/8" rear anti-sway bar will make a huge difference, but again. what to buy. IF Addco have finally put the correct a/sway bar the jpaz had them make, into production, then that is what I'd get. I do NOT like the so-called correct one they currently sell for the 71-73's. It is about 1 1/2" too wide (3/4" per side) and the mount area is on a curve. I am going to look into changing mine later along with shocks. Below is a couple of pics to show what I mean. Not the best angle, but I think you can see the offset and the mount bracket right at the curve.
