Kyle M's Ranger Rebuild

How can moving inboard make the spring rate different?

Moving the springs inboard gives the axles more leverage = softer spring rates while flexing while retaining decent road manors and load capacity.

So why don't companies already do that? I'm trying to figure out the downside of doing this...

Stability and roll control. Explorers are like that.... but their frame is wider.

 

[Josh40601]

ahhh, ok. So not a good idea on a DD huh?

 

[wahlstrom1]

If you know what your doin, it aint an issue.... like driving any lifted offroad rig.

Man I love this truck (and it was one of the trucks that made me pull the trigger on getting a Ranger).

I'm strongly considering giong down the same road with inboarding the rear leafs when I get to that point (which is coming up pretty dang quicly). I'd be real interested in hearing about the on road manner (Off road should be awesome). Even just moving the springs in that little bit will make a huge difference in the amount of rear flex/movement.

looking good kyle, might want to look into putting one of those toyota style shackle mounts in the rear that have a johnny joint in them to keep the springs from twisting so much.

keep up the work it keeps getting better and better

I have plans for a heim in the shackle once I get rthe extra money to build them. I wanted the uniballs in the shackle mount, just didn't want to pay for em. I had enough into it already.

Yup, that is correct!

Thanks, I will let you know how it all works out

nice progress Kyle

keep it up buddy.....

lookin good man.

Inboarding the springs does nothing to the spring rate of the leaf spring itself, but it changes the effective wheel rate. I got in a huge discussion about this on Pirate, and ended up looking like an ass. I now understand.

The force required to move one wheel a certain distance(articulation) has lessened. The force created by the spring is still the same.

6 of one, half a dozen of the other. It will articulate better, but will have the exact same load carrying capacity as before (assuming the axle stays horizontal during operation).

you got it, in simple terms....alot more leverage on the springs

 

[Bray D]

yeah, I'll see if I can find the thread. It was about TTB and why the springs are stiffer than on a solid axle. I don't think anything I said was wrong, but I was claiming that what he said was, and he wasn't haha. There was tech. I learned. Mission accomplished.

You are correct. I didn't want to get into the whole discission, but really it will act like it has a lesser spring rate since there will be more leverage on it.

 

[Andres629]

My question is... why did you stay with leaves? Was there an advantage over linking it that I am unaware of? My springs will be inboarded like this when I get the full-width, until I get around to linking it. Just curious.

My guess - time and cost.
