So I got the CC782s and K160039 for my 2000. The isolators don't fit in the springs very well and technically 2000s are not on the 782 fitment chart. Is a mod necessary? Are they really the best choice? Should I just install and let the weight of the vehicle force them to seat?

TIA for any thoughts.

 

The issue is that the top of the pigtail is bent in a little bit so it's no longer round. Stock isolaters have a metal support ring so it's not flexible. I'm pretty sure the weight of XJ would squash it in there but I'm really not liking to do it that way. I could go back to my original plan and use Crown 52001125 and a slightly larger spacer.

Fitment of CC782 4.0 XJ 4WD is 89-90 and 92-96 so it would appear a lot of people squashed 'em in!

In the instances where guys used 782s on 1997 to 2001 they also used spacers so perhaps that allowed a little more leeway. And indeed, the Teraflex 001905175 3/4" Coil Spacer, which is what I would use cause I only need about 1" of lift, claims it will fit 84-06 Jeep Cherokee XJ. Mayhaps I shall call tech support of Moog and Teraflex and see what they have to say...

 

It can't hurt to call.

 

Got my Teraflex 001905175 spacers today and indeed the lower lip is a little smaller than OEM and fits easily (perhaps even a little sloppily) into the top of the CC782, so going to go ahead and install the 782s.

 

Dave,
Can you give us some more info:
1) did you leave the stock isolator in place and use it in conjunction with the Teraflex spacer?
2) after a few months of settling, what are your hub center to fender well trim measurments?

Background: I installed the CC782 coil on a 96 Country Feb 2013 and they have held up well. I left the stock isolator in place and did not use any spacers. Today's measurements are 19 1/8" from hub center to fender well trim. I rebuilt the entire front end at the time and it all came out well. I was always very happy with the ride and handling of the resulting package.

I'm now getting ready to do the same on a 99 Classic (my daily driver) and have the Daystar 1.75" spacers. Removing the stock isolators, the package should result in about a 20" measurement (hub center to fender well trim). I'd guess that's approximately a 2.5" lift. I'm agonizing over whether or not that is more than I want - I might be better off with the .75 spacer (and removing the stock isolator)? The latter option would put me at the same 19 1/8" height as the 96 Country. So, I'm looking forward to your info. A pic would also help.

Thanks,
Larry

 

I used the 1.25" Teleflex spacers and did not keep the stock isolators. Today I measured 20" which oddly is higher than the 19.5" when I first installed them. I put on VERY few miles tho, but occasionally tow a pretty big boat.

I originally thought the variable rate springs were noisy as I heard a "clack" every now and then, but I think it's actually where the spring may touch the stabilizer bracket (I had to weld on new spring perches and all related brackets when I redid my front axle, and I may have put that bracket too close to where the spring would eventually go).
