What setting do you run for 40? I have the 5000x's and I'm thinking a leaking seal has got the best of me. I'll probably be upgrading as funding becomes available.

 

I have run the Rancho 9000 series on a 04 TJ, 06 JLR, 12 duramax and a 2016 JKU.
These shocks are simply amazing. These do make a huge difference on any Jeep.
I'v been impressed on every vehicle I have installed these on.

 

I've been running the RS900XL's for a few years now and let me make a suggestion: While these are adjustable, they are not always going to be adjustable. At least, that has been my experience. The mud, sand and muck will get into that tiny adjustment mechanism and freeze it up. It's just plastic, so you'll risk breaking it should you try forcing it. So, whatever you do, decide on a compromise setting that works for all of your driving, then leave it there. For that reason, I advise folks that if less expensive Rancho shocks that aren't adjustable are a good compromise, don't think they gain anything by purchasing the more expensive, but "adjustable" ones. For the money you pay, that adjustment mechanism should have been better made.

 

Thank You, I'm excited to get mine offroad soon... Things have been crazy lately and the Jeep is just hanging out in the driveway.

 

Thanks for the tip, I had others mention that as well. I'm on it.

 

I have 4 years and 45K on a set of 9000's. I followed advice on this forum and greased the adjustment knobs and also sprayed clear coat on the shock bodies. So far the shocks still look great. I do use the adjustments, I prefer a stiffer setting for mostly highway use and softer for off road. The only place I've felt the shocks can get overwhelmed is on sustained washboard roads.
