Featured Technical 40-41 FORD PICKUP PARALLEL LEAFS

Yep, you have to factor in the motion ratio of the independent front suspension. That is where the difference is.

 

Drugs of most sorts have never done anything good for my cognitive abilities... Brother, we're trying to call you home but you're lost in the fog...

If I hadn't had a helluva day, I'd take a better shot at explaining this but I'm too tired (and have a busy morning tomorrow). A three hour one way trip both ways through Seattle today with each north-south corridor effed-up somehow took it out of me. If clarity hasn't dawned by tomorrow evening, I'll go at it then...

 

I have been there for years , with spinal issues . 4 fused in my neck , 2 herniated in lower back , 3 defined types of arthritis . Hang in there, my Friend . If I lived near you I would be there to lend a hand . About the springs , my thoughts buy the used springs , use one long leaf from used packs to raise the springs in your PU and drive it like you stole it .

 

Just looking around I found some old shops, putting this info out there for others if needed.

I love the HAMB but,, For every problem you bring to the board you will get an unbelievable amount of options. Some sound, most not. In this case it's just plain physics. One item (leaf springs) isn't pushing. Place another item in its place (insert coil over spring) that does push, and something is going to move. That's all that needs to be done here. And that is just another HAMB option, your move.
And I'm OUT. I have other work to get done.

 

Sorry about your health problems! Really throws a wrench into doing things. I have the same CE springs and mount on my 37 and haven't had the sag. I didn't change the mounting though and do have blocks under the axle. The longer shackles should help. You could switch the shocks over to air ***ist shocks that allow some ride height adjustment, and just replace your CE shocks.

 

When I was originally building the frame, I noticed the already flattening springs and actually looked into air shocks for the back. I think I posted a question or two in my build thread about their use and opted against the, in the end mainly because they didn't offer them chrome plated which is just rude!

I'll get this handled. If I was feeling better, I would be working instead of typing.

 

Coilovers will accomplish the same thing as air shocks, just without the annoying tendency to leak

 

As the morning dawns and clarity returns I have a better understanding of what you gents are saying about the movement of the front end compared to the rear. I should have given that more thought.

Between my back and my vertigo I am a mess at the moment. I haven't driven a car in 10 weeks and even riding in one makes me nauseous after half an hour or so. It even makes working in the shop a bit dangerous for both myself and my cars. But this will all p*** and I will dive back in on the PU and start implementing the plans we are discussing. The used springs are probably an option, my daughter happens to live on Mt Hood and is coming over for an eggnog on Thanksgiving and watch Christmas Vacation with me (tradition). She can stop by the yard in Sandy and grab the springs through town. I'll take them apart and have a friend sand blast them for me so they are ready to play with. And like I said my new shackles are plated and ready to pick up, my wife will take care of that on her way to the office and drop off the frog mouth scoops from my roadster. The aluminum they were cast from just doesn't hold a polish very long and I am tired of them looking dull and streaky. Chrome cures all. Maybe I should have my ears and spine chromed.

 

Hey Bandit, sorry to hear of your back issues. I have had my share of spine problems and know how painful and frustrating it can be. I have been enjoying this thread. I am not much of a technician/engineer on subjects such as this,so I have kept my mouth shut.
You mentioned you had considered air shocks in your build thread. I probably shared this info with you back then. I have installed these air shocks in two different 38 and 40 sedans with good success. I put them in to adjust ride height when we knew the car would be carrying p***engers in the back seat. It was a cheap and easy fix for that problem but would also help with general ride height issues. The only problem I had with them was maintaining the pressure in the shocks. Those plastic hoses and connectors were hard to seal. Speaking of spell check ,I am completely sober and had to spell maintaining 4 times before spell check would quit flashing it's little red line . Be careful out there in the shop.

 

I installed firestone overload bags on my daily PU along with an onboard compressor, all controlled by an app on my phone. I run around with maybe 10-15 pounds in them, when I trailer my cars, I put about 75-85 pounds in the bag (depending on what car is in there), and it lifts the rear end of the PU 4-6" and adds a ton of support to prevent the trailer from bouncing. They also lose air when the truck sits, I can hear the onboard pump come on when I start the truck but only for a few seconds. If I went to air shocks or overload bags on the 41 I would likely add a pump as well.

 

I used air shocks on the rear of my roadster with great success. They were for a VW.!
I had a five leaf spring for a nice ride, but with a travel load of everything but an engine hoist , it squatted miserably. Would have NO rake. OMG!
Load up the trunk, air them up to get the ride height, and hit the road.
The VW valve rate let it ride nice, whether loaded and aired, or not. Both ends were rubber bushed. And painted the same as underneath the car they looked right at home.
And the Schrader fill valve was in the trunk, so it didn’t show. I used Chevy Suburban air line and fittings.
