Bypassing the need for the fox shocks?
Sorry I can't answer that one. I will say that I ran the gasser Rubicon Fox shocks when I changed springs. I went back to my stock Willys shocks and like the ride much better.
Keep in mind for factory OEM suspension tuning, the usually install a odd part number spring on rear left and a even part number spring on rear right. This is for the gas Gladiators. The reverse is true for Diesel due to the Fuel tank being on the other side. Front springs follow the same pattern.
The diesel gas springs are soft from what I've heard. Sport S diesel springs may be better. The Rubicon springs bottomed out if I remember correctly.
My rubi take off part numbers are the same as yours, going to install this week. How could I tell which are left and right side?As you can see my rubi take offs are the very first ones mentioned by the OP. The rears are the 450ab/451ac (although the OP states that’s the ones from a steel bumper rubicon which is incorrect) Mine I know for a fact came off a non steel bumper Rubicon.
In any case prior to adding my Teraflex leveling kit which gave me another 1.5 inch lift just the rubicon suspension alone I got just under a half inch in the front and just under an inch and a half to the rear from the stock set up(for the most part as as you can see by the numbers). Which that in itself was an improvement from my stock overland. And again this is with non steel bumper rated rubicon springs. Even more id imagine for those with those springs. The exact measurements for me were…
Measured ground to fender on 35” Equivalents
Stock
Front drivers: 37 1/4
Front pass: 37.5
Rear drivers: 39 5/8
Rear pass : 38 3/4
After Rubicon Suspension
Front driver: 37 3/4
Front pass: 37 3/4
Rear driver: 40 1/8
Rear pass: 39
Not sure why there was a slight difference from one side to another if I had to guess its due to the gas tank being on the passenger side and depending on what my tank was at within measurements which usually stays pretty full. Also tire pressure may play a part but I'm generally at 36 psi give or take. But I measured multiple times and I’m sure it’s normal. But in any case it was improvements all around and I am very happy with the upgraded suspension even before the TeraFlex leveling kit. Definitely a cheap and easy upgrade to any non-Rubicon trim that wants a better suspension. So as a bonus adding the TeraFlex for me with what I got from the Rubicon suspension I Have a 2 inch or more lift Without technically having a full lift at all just spacers and upgraded shocks and springs
Picture with the top off is totally stock and with stock tires (although my measurements above are with my current 35 equivelent Coopers, so its not a difference in tires, the pic is just a visual for you). Pic after that is with rubicon suspension ONLY and not my leveling kit. Best pics I could find from my set up then.
But the diesel engine is heavier than the gas engine.
Hmm used to be ya would, dont know
good question. Go to a car kot this weekend and look at the springs on a Rubicon
