Ride was so much better than the choppy original 06 sport package shocks.

Yea they told me $900 to replace one shock. I laughed and did it myself.

yup heres their ebay listing for the full set

It's unfortunate Bell Lexus wants $700 for those. I wanted to grab the set that was on the classifieds on here a while back but completely forgot about them, they definitely don't pop up often. I still regret just replacing the one side that was leaking instead of both on the rear, but eh, at least the used part had similar mileage to my IS.

As for the OP, if you really only plan on replacing the one that's leaking in the rear, I'd at least grab a used OEM one instead of an aftermarket part. Best to replace both the repairs.

Installation is very standard, can be done by any mechanic, and shouldn't cost more than maybe 2 hours of labor ($300) per pair.
The base model Lexus / Koni rear shocks are defective and well known to fail prematurely and leak oil -- there is a Lexus service bulletin alerting dealers of the chronic issue. The front shocks are not flawed and there's no need to replace them just because of the rears failing. Shocks should always be replaced in pairs but there is no need to match front and rear.
Wow, the 2WD shocks are a lot cheaper than the AWD shocks.

I just bought a set of F Sport AWD shocks. Cheapest I could find was $650ish shipped. I've been looking at these on and off for a couple years, and decided I'd better grab a set before they're not available anymore. Everything I read says they were discontinued years ago, but they're still widely available online.

That's how I interpreted it too -- out of production, but still plenty (for now) of new old stock sitting around.

Keep in mind that bushings which are pivot points can not be tightened down while the suspension is hanging free.
If you do let it hang free and tighten the pinch bolt, the bushing(s) inner or outer will be destroyed once the car is at ride height.

Leave the pinch bolts loose and tighten them once the vehicle is sitting on its own wheels. Better yet is to let it roll a bit and then tighten any remaining pinch bolts securing pivot points.
