    For my build i will be installing a 32v DOHC 4.6 and a 5 speed manual (not sure if that changes my options)


    but, for the rear end I have an 04 Ford explorer axle (3.73, limited slip, discs)

    The truck still has the stock leafs on it, Eaton said it would be about $375 for new springs in stock height or lowered to my liking.

    Since I will have to weld new perches onto the axle tubes I figured it would be best to just mount the axle on top of the springs and MAYBE notch the frame if needed.

    What would you recommend I do for the leafs if i go this route? Id hate to waste almost 400 bucks only to find out that the rear still sits too high or if i get a lowered pair the frame will need major surgery.

    Also, where is the best place to get spring perches?

    We used Explorer 8.8 on top of stock springs and c notch on frame. We used Exp u bolt, narrowed the bottom Exp plates and Moroso plates like your picture. Works good.

    How much did you need to notch the frame?

    A lot of f1 guys are re locating their spring hangers up higher on the chassis to get them low, but I cannot ell if their using drop springs too. All depends on how low you want to go. There are a few f1 build threads on here. One truck is a red primer and he is scrapin low, but I forgot his combo.

    Anyways, do a search on f1 builds and you will find your answer.

    I've found a ton of threads. Nobody is using drop springs. They're just relocating the rear mount and calling it good. I think I can avoid that by using the 1" drop springs (same price as regular height) and axle flip

    Not exactly the same but close. On my 53 F100 I used longer shackles, moved front spring hanger to the top of the frame rail, then started removing original spring leafs. Once I got to four the ride is perfect. Of course it can no longer haul much. I did notch the frame but don't think I really need it.

    Greetings! Have replaced the stock rear springs on my '48 with springs and hangars from a small Ranger pickup, before you remove the parts from the donor frame record the distance from the front hanger bolt to the axle centerline, the distance from the rear hanger bolt to the axle centerline, and the distance from the front to rear hanger bolt just to make sure your math is correct. Best of luck with your project.

    what year ranger? do you have any pics of the project or how the truck sits now?
     
  11. ...save some $ and get yourself some truck leaf springs that mount to the frame like yours, on the sides,...these are off a late 60's early 70's Dodge truck....Chevy/Ford will work also, just get ones about the same length as your originals. I got these from a 2-wheel trailer that a guy gave to me.
    ..then mount your rear on the top of the leafs and use blocks to get the ride heigth you want. I may need to do a small notch on mine yet.

  12. I've done 3. I just put the axle on top of stock springs and C-notch. Cheap and easy.
     
  13. ...doing it this way will really lower your truck, maybe too low.
