My guess is they would lower the height, expecially with my M68, but that may be able to be fixed with blocks.
That is just my guess, I would like to hear is from someone that knows.

 

I'm not sure about the Explorer springs but most modern springs are too long and will interfere with either the rearmost running board bracket and/or rear bumper bracket if you try to use them. I am using a set of 90 Dodge D-50 springs which are actually shorter than the F-1 springs on my 49. I mounted mine under the axle because I wanted to lower my truck but you could use them over the axle just as well. I made 'L' brackets which mounts the springs to the side of the frame rail much like the original springs...

 

You should be able to use the Exploder springs as long as you get the hangers and shackles to go with them, they will give a much better ride than the OEM that are there. I used springs from a 88 Ranger in my 53. If a taller stance is wanted, the BroncoII of the same vintage has more arch to the springs.

I'll never understand the desire for disc brakes on the rear these trucks, with the nose heavy stance and light rear end you'll have to reduce pressure with a proportioning valve to the point where they are no more effective than drum brakes. A well thought out system of disc/drum brakes works well. My entire system is from a 87 Town Car and I couldn't ask for a more effective or balanced brake system. Just my thoughts, I could be wrong

 

Hi Wayne,
Thought maybe you could shed a little light on a potenial problem I have with the 97 Explorer rear axle. If you remember I am putting this in a 51 F1, but with a Mustang II front suspension. I have the frame assembled with the front end and with the rear axle and now I see that the rear axle pinion flange is not perpendicular to the ground. I measured the angle and it is 10 degrees pointed to the sky. I can put tapered shims in between the spring and axle perch, but what angle would be considered to be acceptable and not have a lot of U" joint failure. I was thing maybe 4 or 5 degrees. Your opinion would be appreciated greatly.

 

Am I the only one besides 56PANELFORD that thought this was an amusing thread title? I almost fired something off on it the other day then thought I better rephrase that. LOL
Anyway picked up a 8.8 of a 95 Explorer with the disc brakes 3.73 gears for my 54 M-100. with both springs, chrome rims and tires at Bucks PAP for $145.00 You aren't allowed to use Jacks there so it was a PITA.A good cordless recip saw would have saved the day I'm using the spring shackles off a newer Ranger. The tires are rubbing but I don't plan on keeping these rims plus I plan on tubbing the box. good luck with it

 

Ten degrees sounds high. The angle that the rear end is mounted depends on the angle of the engine and transmission. If the engine and transmission is pointed down three degrees the rear end should point up 3 degrees. I'm no good at describing pinion angle. Do a search on "pinion angle". There have been many discussions here on it.
