Topic: Add Rubi suspension to yer TJ?!

[Traceycon]

I just removed all of the stock 84,000k mile 2001 4 banger TJ suspension & 15" wheels off  today--6 hours except for an alignment and replaced it with brand new take off 2006 Rubi stuff.
Stock


Here is what the donor Rubi looks like now!


So here it goes:

Weight from the BFG AT 30-9.5-15 stock wheel/tire @ 24.5lbs to the 245-75-16 Rubi stock wheel/tire @ 34.0lbs.  That is a un-godly 9.5lb gain per wheel/tire! :evil:  :evil:   The new spare BFG measured @ 28.125" height....... :?   The MTRs measured @ 30" :D

All of the trailing arms, steering links, swaybar links bolted right up!



Measuring the stock set up was 32.5" at the front fender flair and 33" at the rear flair.  Rubi addition showed 34.25" on both ends.   That is the difference of the wheel/tire combo.

Here are the differences of the front & rear coil springs off both vehicles:
The stock TJ Fronts #71765-52088127AA @ 0.475" od coil & Rears #71765-52089104 @ .590" od
Rubi stock Fronts  #71765-52088129AB @ 0.505" od & Rears #71765-56052335AA @ 0.605" od.

The ride is a lot stiffer on the tarmac, obviously, though no realistic suspension lift showing.

I was told the springs are the same from a Tj to a Rubi. I guess the rest of the suspension is not though.

[Traceycon]

I hate to say this, but you were told wrong.   :oops:
The wire used for the springs is thicker for the Rubi.  That is why I put a caliper to the spring to see if there is a difference.

[Tall Boy]

oh, no kidding. I got a set of rubi springs off of a 2003 rubi in my garage I'll have to double check it aginst my old springs. the dealer told me there was no difference though but dealers can be wrong from time to time. Some of those guys are just business majors who know nothing but business. I bought the pro comp 2 1/2" lift kit instead of putting those on. I am trying to pawn em off to a guy with a toyota 4 runner but he don't want em. I saw a cute girl driving a 4 runner I should talk to about it.

I am comparing the 2001 stock springs to 2006 Rubi springs.

I'm using 2005 Rubicon Unlimited springs on my TJ. There is a 3/4" to 1" height difference. I measured a 2006 TJ sitting in the parking lot for comparison. Getting under a stock TJ was hard!!!!

You can get the same lift with stock TJ springs using double rubber isolators. These are the rubber pieces the top of the coil rests.

I also suggest you use longer shocks. If you go with disconnects for the front sway bar, check your brake line lengths at full extension. An upgrade for longer brake lines in a TJ is to use YJ front brake lines. They are 3" longer with a longer steel end that bolts to the caliper.

[Traceycon]

The reason why I did not install a BB was the budget would be blown out of the water with purchasing new longer dampers.
I'll run the stock Rubi dampers for the time being.
Over time and useage will cause suspension to sag; coils, leafs, rubber bushings start to fail.  The stock TJ springs were not saged at all, hence no lift.  So with the purchase of the wheels, I got all of the stock underpinnings and figured, why not put the Rubi stuff under.
The ride is so much better.

Anyone know where I can get rocker panel guards and body panel armor like in this picture?

It feels good to get new springs under the chasis, yeah  :D . Nice job. Those old springs and other stuff there are probably worn down a good spell. Time to break em' all in up there in the Rockies aye. I was there last month visiting family in Denver from California. Took I-70 there, and I 40 back from the I-25. When we pulled into Trinidad we were amazed at those cobble stone streets, and old turn of the 19th century buildings. Beautiful state from what I saw during the trip. Never really been wheeling there though except for up in Morrison a spell.

so could you have swapped JUST coils and shocks and had the same final product?  if so, why the extra work?

Over time and useage will cause suspension to sag; coils, leafs, rubber bushings start to fail in all vehicles.
