Does outboard springs = more stability???

    When i install the waggie axles, i know i have to outboard the front springs to fit the frame on the axle, but i was thinknig bout outboarding the rear, will this give a bit more stability?? And will it cost me that much flex on the springs?? I think i remember hearing that the outboard will limit flex but give more stability, just wanted to make sure.

    Thanks!!!

    The way I understand it is that outboard will be more stability but reduced flex. I guess if you want flex then you forfeit some streetability. The same holds true for the other way around.

    On the CJ5 I'm building: Outboarded front springs because of D44 cast spring perch and frame width perches on the rear because it will not be that much of a street machine :)

    Sounds like the bus is gonna be a monster by Mayhem :twisted:

    The axles probably wont happe nat Mayhem unfortunately. I am going to get my cage done next, then maybe consider doing the axles, i will need to regear and rebuild them so it wont be easy and cheap. And i am enjoying the heck out of driving it around :) But eventually the waggie axles will work their way on it

    Outboard springs will reduce flexibility in that the lever arm acting on the springs is shorter, so travel at the wheel end of the lever arm will be reduced for any given spring deflection. Stability will be enhanced because the loads on the axle will be much farther apart. Ford's commercial about the F-150 going over bumps demonstrates that. One other factor to consider is how much axle you have beyond the srping perches. Our early CJ's don't have much space outboard of the springs compared to later models.

    Theoretically, it will limit flex, but the late 5s and 7s & 8s had s[rings about as far outboard as what you will have in the back, and thay flex just fine. Also, the YJs are even farther outboard (same width as waggy in front), and have no problems either.

    From what I have seen, your flex is going to be limited mostly by your spring rate & design, shackle length, and ultimately- if you get the first two right, shock length.
