Fox 2.0 Pro Resi shock on Superlift

[TrialByFire]

After blowing out my Superide shocks which I got with the Superlift back in May, I decided I needed something a bit beefier. Matt suggested the Rancho RS19287, an RS9000 Pro Series remote reservoir model. Today, I decided to check the full flex limits (swaybar disconnected) of an XK with the Superlift. With a compressed lenghth of 18.5" and an extended length of 30.5", the following photos show that the RS19287 should be a perfect fit. BTW, I ordered a set after taking the measurements and will post the install photos here also.

There are a couple of shots which show some other problem areas with the Superlift like the rear drive shaft rubbing the fuel tank and some very close tire clearance near the upper spring mount.



31" at full extension...


The compression side...


Max compression


Back on the flexed side, the spring is quite loose...


The brake line is the limiter...


Here is the problem I have been having with the drive shaft boot. I cut off the side of the tank guard because it kept catching on the boot and causing small tears.


And here, another clearance concern. Not touching, but close!

A couple more of the coil gap. Would OME HDs fill this in?

Great info man!

I'll measure my OME HD's when i get them, but id expect them to be even shorter than the SL springs..

Another thing you can do is measure what the fully extended length of the shock would be at the point that the coil just becomes loose.... we can go back to the shock specs and try to find one that'd work as a limiter (or, you can use that length to get a set of limiting straps.

I think that would seriously limit the flex. As seen in the photo, that would shorten things by 3 inches! With the SL, there is no chance of the spring falling out like there was with the RR since there is a 4" extender on the centering bumper. The Superrides that I'm replacing were about 27" extended and that gave me less flex than with the old Bilstein 5150s I had on previously. The Rancho's should limit right at the point the brake line gets tight and as long as the head doesn't snap off, like the Bilstein's did, they should be perfect. My only concern is that the diameter of the Rancho's is too large and will interfere with the SL drop bracket on the passenger side (the Superride touches).

[Matt]

That's true that it would limit flex. I guess the only concern there is if the spring re-seats properly... but that can easily be resolved with a floor jack and a few minutes of time.

If the ranch is too big with the reservoir piggybacked, you can probably find a spot to mount it remotely.

wow...

Nope... not even close.

Oh well. Guess I'll stick with the SL springs.

Here is the update on the Rancho shocks:
I cancelled the order (twice). It seems the RS19287 is discontinued. A couple of companies showed stock on-line and one of them even told me over the phone they were in stock but after running my credit card waited for me to call a couple of days later and then told me that "the factory" had discontined the model. I now have a pair of Fox 2.0 Pro (12" travel) on order and will hopefully have them on Friday. I will probably have to extend the brake line drop bracket a little bit (1"?).

Man that sucks... but, at the same time, maybe it's for the best? Can't go wrong with the Fox shocks!
