Fox reservoirs, or bilstein?

I decided to remove my spacers. And stick with my zone 4" lift for now. Going to replace the shocks, and I'm looking at bilstein reservoirs, and fox reservoirs. Any one run these, and how did you like them?

First question...do you really need reservoirs? They look cool...but 90% of Jeeps don't really need them.

If you are doing high-speed desert pre-running/dune jumping, then yes, go for the reservoirs. If not, just go with what you prefer and save the $$$ for other add-ons.

If you want a smooth, adjustable ride, look at the Rancho 9000's.
The Fox shocks are aluminum with a nice, shiny silver appearance.
The Bilsteins are the most common shocks used.

I don't own either of those shocks but have been in several jeeps with the teraflex prerunner kit with the Fox shocks and they are nice. When my ranchos bite the dust I will add the Fox shocks and maybe the speed bumps. I see a lot of jeeps with the Fox shocks in my area.

I can't tell the difference in ride between my Fox RS and my buddies Xj with Fox (no RS). we are both running metal cloak springs. My other friend is running bilstein 51s. the only difference in ride between his and my JK is the up travel is smoother and less harsh on the fox shocks. bilsteins are really pressurized. either way you go...they are both great shocks.

Just built a 2014 JKU with AEV 3.5-4" lift w/ 35's . Went with the Bilsteins and could not be happier. Unbelievable ride ( better than stock) Considered the resevoir Fox set up, but my Jeep is not running Off road enough to justify the price. They are nice shocks but I wanted to put that extra $$$ elsewhere on my Jeep .

Fox are usually valved a little sifter than bilstein they have a nicer machined body.

Quality: both are top notch I had bilstein on my pre runners and race truck and BMWs built for track....I have fox on the last 3 jeeps and in my dh race bike and plenty of years experience with both....both great shocks can't go wrong with either....

Reservoir shocks will have more travel than non reservoir shocks for the same application, the IFP is In The reservoir instead of the shock body it takes up about an inch of shaft throw if in the body. That's why the reservoir will have more travel.

Oil in shock is what slows the piston for damping the more capacity the less fade you will get so on a longer wash board road the reservoir shock, will stay more true to its behavior.
Shock,s that are nitrogen charged (fox/bilstein) versus an emulsion (most cheap shocks) won't fade the pressure of the nitrogen on the oil allows it a higher strip point or where it turns to foam from cavitation or high speed movement allowing bubbles to form and then the piston passes through those quickly ie fade...
They use nitrogen because the molecules are larger than air so less leakage at the seals over time, it doesnt have moisture in it like air and with larger molecules it doesn't fade like air does when it heats up....

Hope this helps a little....


Both are great can't go wrong with either....

Thanks everyone for your input. Brut4ce- thanks for breaking it down so I could understand it. Think I'm gonna go with the fox shocks.
