    Hello,

    I have a frankie that is a CJ5 on a C3A as far as i have been able to tell over the years. I know BDS is the way to go when lifting, which i plan on doing someday. But also considering going ahead and replacing the C brackets with newer styles. Is there a difference in the bolt hole size on the frame hangers as i am trying to also plan for the new springs which seem as though to get the lift i need to go with CJ5 springs.

    Thoughts...

    BDS springs are popular as they hold up, ride and flex well. I have a set of ECJ5 rears in the front of my 68' CJ5 (non BDS on the back). Works really well. Something to think about is this: If you do indeed have a CJ5 tub on a CJ3a frame, which obviously is unusual, keep in mind that the springs are different lengths., thus the hangers and shackle bracket spacing is not compatible between the two models. If you want to run ECJ5 springs you'll need to move your srping hangers & shackle brackets and maybe need to lengthen the flatty frame. With this you'll want to install new hangers anyway. If I remember right the CJ3a springs are 36.5" long front -x- 41" long rear. ECJ5 springs are 38.5" long front -x- 44.5" long rear. If you do this you may as well run ECJ5 rears in the front as well.... or YJ or late CJ springs.

    Thanks. I would really want to do that fab change. I will check the spring length as best as I can to help confirm what I have. I just want to bolt right in a compatible spring and shackles.

    Not sure on color or if it’s an actual Jeep color. Looks better far away and in pics. I like it though. It’s registered as a 63’ Willys CJ5 but not much is really that. I wonder why my signature block is not showing. I’m on my iPhone right now though so maybe only shows up if I post from my PC. It has more details

    If I turn my IPhone sideways, it shows the sig lines.

    JonBrew, as to spring hanger compatibility, both cj3a and ecj5 springs are 1.75" wide, thus they are compatible. There may be a difference in bolt size, and I'd think that this could be addressed by otherwise sizing up and drilling out the hanger hole and using a hard polly bushing (that can also be drilled out). Something else to consider is an asymmetrical spring like the old Holbrook long-leaves (not sure if they are being made now). They achieved a longer spring on these old jeeps with an off center axle placement on the spring. With this, you may be able to avoid frame modifications and only move the spring hangers and not the shackle hangers.... being careful to line everything up correctly and thoughtful of shackle angle. And lastly just as an FYI, the late CJ and YJ front and rears are all around 44.5" long, eye to eye.
