Bilstein in Landcruiser

Ignore all the suggestions to get aftermarket shocks. I don't know why I'm going to pos this for the umpteenth time, but here goes.
I am a former Product Planner for GM and Lexus/Toyota. Shock absorbers are carefully tuned to a vehicle's particular suspension geometry, spring rate, roll center, mass, center of gravity, etc. Buying aftermarket shocks, means you're getting generic settings that are absolutely, definitely NOT specifically tuned for your vehicle. No shock maker has even 1/100th the budget to do that.
People see the cool ads for Bilsteins, etc and replace their tired shocks and think the Bilsteins are the 'best ever'. I'm here to tell you we have done consumer testing and we could have put new shocks from Outer Mongolia on a person's worn out car and they'd rave. It's a 'change' so it's good. But they have no idea how good the vehicle COULD have handled again if they'd put new factory shock on them because they're victims of the Bilstein marketing campaign.
Take some good and sound advice. Call Cdan and order 4 factory LandCruiser shock absorbers. They're perfectly matched to your vehicle's every aspect. They're very high end shocks which you'll find when you take the old ones off and they still cycle smoothly. I think Tokico makes them - great stuff. Heck, the rear shocks even have a welded on integrated gravel guard. You'll spend about $100 for all four and they'll fit perfectly.

I agree with you completely on this thread. I do the Bilsteins quite regularly to the audis in my shop, and recently did the Bilstein "upgrade" to a 93 80. The customer likes it fine, I found it to be a bit stiff, and actually not a true bolt in application, because they massively change the rake angle (one of my pet peeves on aftermarket stuff) significantly. I actually ended up cutting down some bumpers for the rear to get it where it wasn't rear high.
The Bilsteins also lack the heat/rock shield found on the factory shocks. Bilsteins are also notorious for gettting really stiff in cold climes, a combination of compacted gas and high viscosity damping, it can get really bad.
Using the 93 as my guideline, I decided that when I do the shocks on my 94, I'll do stockers (mine are original BTW at 110k). After a lot of thought, I decided to see what air lifts front and rear would do to the ride quality before I went after shocks. Really glad I did, since air lifts stiffen up a stock shock somewhere short of the Bilsteins.
I did put Bilstiens in my old 4R, and found them to be a decent match to the MTR's, but I did snap the shaft on one while offroading.
Based on my 20year history with Bilstein, they make some great shocks and struts. But they aren't meant to last near as long as the stock hydraulic replacements, and the non german applications are fairly recent addition to their line. When they did the expanded apps, some got much more development than others (read: I liked the 4R app, I don't like the 80 app)
As a rule, I'd only change the 80 shock to Bilsteins if you have changed something to require it. Bilstien HD are faster reacting than the stock yota shocks, but remember your tire weight. If you go to larger unsprung weight, you don't need a faster shock at all.
If you are looking for a step in the right direction using the stock application, get the stock shock and order up a set of airlift airbags. If you really want to go stiff ride, put 35psi in the bags. Want to mellow it out, put 6psi (min) in them.
