Inboarded leaf springs

[ QUOTE ]
but where do you get more force from?

[/ QUOTE ]

In this instance you get more force by inboarding the springs. Instead of 8" of axle tube you've now got 18" of axle tube pushing on those springs.

What I was basically saying is that IF I decided to inboard my springs, I could use a stiffer spring inboarded and have the same flex as a soft spring outboard.

I am feeling the same as others though, that this would result in too tipsy of a feeling, and I'm going for more travel to try to make my rig feel LESS tipsy, not more, so I've ditched the idea.

I got my 63s today. I'm moving the tank to the bed and putting them on the ouside of the frame. I'm saving the room inside the frame for an anti-wrap bar which I'm going to make. /forums/images/graemlins/thumb.gif

Why do you think people who are after flex try and find springs with the lowest spring rates?

[/ QUOTE ]

Because they want to bolt springs into stock spring mounts and get the maximum flex. I don't care how I mount them, I just want to achieve maximum travel.

As stated above, I'm keeping mine outside the frame.
 
As dan said we run inboarded 63's on my dad's truck. We have had this truck laid over pretty good, and before my father bought the truck it was used by an arizone guy. Ive driven the truck a number of times in the rocks and its very stable. I think its more stable than some trucks because it NEVER pulls a tire.
 
What kind of truck is your dad's? What's he run for shocks?

Nothing is set in stone, I got my 63s today and I'll be tearing my rig down this winter.

I completely agree that the new guys can benefit from the older threads, it was great when we were all new and this kind of thing was "high-tech". :wink1:

I just wish the pics in the older threads still showed.

I definitely want more information and maybe some long term test results from anyone that has done this. My 63's are doing just fine outside the frame but I am modifying my rear frame section so I was thinking I should mount the springs inboard while I was at it. :waytogo:
 
I've only wheeled mine a few times but I haven't noticed that it seemed any tippier.

If you have a brand X 6" spring with a soft spring rate and have a Brand X 6" springs that is HD, the HD will flex less due to the higher spring rate. Why do you think people who are after flex try and find springs with the lowest spring rates?

But, depending on how far the "HD" spring is moved inwards, it could offer more flex than the softer spring in the stock location. The further the spring is inward, the more leverage the axle placed on that spring when just one end of the axle is being forced up.
 
Also by moving inboard you increase the amount of movement at the tire for the same amount of spring flex.

A buddy of mine helped his buddy (SMP, ex-CK5er) do it on a 72 K5 and if flexed like MAD and was pretty stable from all reports I have heard. Someone on here actually still has the K5 in NorCal I believe. I am not 100% sure who though. It is black with a yellow cage.

EDIT: It is Zcarczar that posted above in this thread.

Why not mount them UNDER the frame instead of completely inboard? You could use the front spring rear hanger that DIY4x4 sells & then use some box tubing for the front mount.

Unless there would be too much lift by doing it this way, it seems to be pretty simple. At least in my feeble mind.

OH & nice diggin'!!

LAter,

I had planned on placing 63"s underneath the frame rails when I had a K5. Wouldn't be difficult and would help with the loss of lift when going to 63s. The through the frame shackle setup would loose lift though. Most shackle flips hang below the frame rails a few inches, so placing the pivot point of the shackle within the frame rail would loose a lot of ride height. Would all have to be some custom made stuff, but nothing complex.
 
Come to think of it, springs on my crew cab are inboarded also. Only for clearing the tires though.
 
I don't think its a great idea, K5 springs are pretty far inboard already.

Imagine one spring over the pumpkin and think about how stable that will be. It would flex like mad though :rolleyes:

The further you inboard the springs, the closer you get to that setup.

Having the right springs is a much better way to get the flex you need (52"s, 56"s, 64"s, etc., its been covered a million times on here).

very true. Of course, putting shocks farther out would help with stability, but then with that much flex, have to be shocks with some massive travel.

Been considering inboarding the rear springs on the 88. IFS rigs have them so far outboard as it is...
 
Found this in another thread :haha:

the springs on the formula buggy i'm building were inboarded. I did it for tire room and more flex as there is very little weight on the rear.
 
On the crew cab the plan is to add air bags to help with the stability issue the inboarding may have caused and to add some capacity. Not sure how well that would or wouldn't work with a truck thats searching for flex. The crew cab is a road warrior only so probably won't be a big deal I guess time will tell.
