Factory spring rate differences (Upgrading from non-Rubi to Rubi)

[Willys_Wonka]

Good Lord, you've gone and done it now, The can of worms is open !!!

After just doing this, I am convinced that there must be 1000s of springs and combinations, and what gets installed is probably the 4 closest to the guy who is installing them.

here is what I found:

My original Willy's springs were:
68253658AD Drivers Front
68253659AD Passengers Front
68253587AA Drivers. Rear
68253588AA Passengers Rear


My new springs are
68253591 drivers rear / 68253592 pass rear and 68253662 pass front / 6825XXXX drivers front (spring not tagged seems to be 68253661 - it is slightly smaller than the 3662).

It is all installed. The rubi springs, Mopar LCAs & Daystar 3/4" spacers (all the way around) were installed yesterday and so far, my opinion is very positive. Jeep seems a little "tighter", there is slightly more road feel, no wandering and the 34" tires look better.

When all is said and done, it gained approx 1.75" in the front and 2.5" in the rear.

good luck.....

the end result:

This looks great. I recently installed 60/61 and 91/92 Ruby springs. Current tires are 285/70/17 Grabbers a/t, but thinking about jumping up to 285/75/17 once they are due for a change. I don't have any noticeable rake since I have a tow hitch, bike rack loading the rear, looks level. Do you recommend .75" spacers all around since I do want some wheel well gap?
