replacement shocks, your opinions?

replacement shocks, your opinions?
the shop sez my front shocks are worn out. the lower bushings do rattle. i'm curious, which are your favorite replacement shocks? i'm thinking either Bilstein or KYB, but honestly, i have no experience with air suspensions as on the X308s. i see comments about replacing with coil-overs, struts? and completely eliminating the air system. pls educate me.
i like a nice ride. firm and responsive, but am not looking to run on the track. just a classy comfortable ride with good handling.
ideas? i have great respect for the Voice(s) of Experience on this Forum.

The x308 does not have "air suspension" -- you may be looking at something that speaks of the old X40's rear leveling. The later XJR's used a shock that was capable of two setting - but no "air"
I think you will find that most who used something other than the OE shocks wished they used the OE shocks.
KYB make a fine product -- but the reports are that they are way too firm for the Jaguar. The shocks are a very important part of the Jaguar suspension.
Do some searching prior to spending the money.

If I'm understanding this correctly, all of the information posted here is in regards to vehicles that DON'T have the CATS active suspension correct?
How do I know if I have CATS? What would I look for?
Also, I thought I read somewhere that CATS wasn't implemented until 2000 or 2001?... or was it an option before then?
Thanks for all the great info Jim!

Hi
Look at this forum thread on Cats suspension - view post# 10 &11 (mentions shock harness connections):
https://www.jaguarforums.com/forum/x...acement-37895/
During an internet I did find a 1999 XJR that was sold and it listed: CATS adaptive suspension as one its features.
I found that the front adaptive cats shock absorber part number is MND2140DC.
I did a internet search with the part number that lead me to the jagbits website - here is the information that jagbits shows:
Fits: Jaguar 1998-2003 XJ8 WITH ADAPTIVE CONTROL SUSPENSION OPTION
Code: MND2140DC
Also shows Jaguar XK8 & XKR 2000-2003 part number MJB2140EB:
FRONT SHOCK ABSORBER WITH ADAPTIVE SUSPENSION OPTION FITS 2000-2003 XK8 AND XKR. Does NOT fit cars with R performance Brembo brake option
Info on Rear shock - Part #: MJB3540EB
This info from the britishparts.co.uk.com
MND2140GD
FRONT SHOCK ABSORBER 2 REQUIRED
WITH ADAPTIVE CONTROL WITH SPORTS SUSPENSION
JAGUAR XJ8 X308 - XJR 1997 - 2002

I could not find definite info on the CATS suspension that shows model years it was introduced.

The shock installation was fine, although it should be noted that the upper threaded rod of the shock is a different diameter than the original CATS shock (this was necessary because the CATS shock mounting shaft has a larger bore to allow the wire harness to pass through the center of the shaft).
Thanks again!

thanks to ALL of you for the useful info. YeldogT makes a good point,
"Do your research before making a purchase decision."
This leads me to a simple question: Do ya think Bilstein makes an X308
shock with CATS wiring? Low volume /demand makes me skeptical that
they would go there.
I am in the process of confirming that my vehicle DOES have CATS.
(car is at the dealership right now, awaiting my arrival to bring it home
after paying to replace one of the air conditioner blowers-- talk about
a breathtaking expense!!! i haven't seen the ticket, but i'm guessing labor
was $1500 of the total-- but damned if I'm qualified take the dash out of
any car, let alone a nice Jaguar)
therefore, even though i make a pretty good living,
i WILL research alternatives before paying the quoted
$900 parts + labor to replace the front shocks. The quote
price alone makes me inclined to think this vehicle does have
CATS.

Hi
I Just looked at the price of the CATS shocks on Gaudin Jaguar website:
Cats (adaptive)
Comfort
Front shock list price $426 discount price $319.50
Rear shock list price $467 discount price $379.44
Sport
Front shock list price $426 discount price $287.63
Rear shock list price $467 discount price $350.25
These are the prices you would probably pay at the dealership parts department.
The prices are usually charged at a higher rate on the service order quotes by Jaguar Dealership Service department.
If you had front Cats shocks, the parts costs would be at least $900 (then you have to add the labor changes on top of that) at the Jaguar Dealership.

But, if they're there, and the car is programmed to use them, then there would be 'Suspensions Fault' displayed if not plugged in? Unless it can be disabled via IDS or before it left Jaguar, in which case it'd be pointless to supply it ready, and not fit them, if you understand.
The other option, if the car was originally fitted with them, then the owner replaced them with standard shocks due to the price, I've seen this a few times on here.

*******************
Fred sez: Jim is RIGHT ON THE MONEY. i was thinking CATS, because
i couldn't conceive that cost quote on "conventional" shocks. WRONG.
i have seen the Bilstein Sport shocks (non-cats) for $240-ish... and i
actually consider that to be reasonable.
at least now, thanks to the knowledge base here on the board, i know
what i'm gonna do. I'm gonna buy those Bilsteins.
