I've got Fox 2.0's on my 2018 F 250. Got a little over 52K miles on them. I'm thinking based on the ride I'm now getting that its time to replace / have them rebuilt.

Any thoughts out there on getting another set of 2.0's versus going with another product.

Mostly driven on the street and used for pulling my trailer. I do some mild to moderate off road driving.

I run Michelin Defenders 295X65 / 20's.

 

Ordered a new set of FOX 2.0's as the current ones have about 55K miles on them.

The cost to rebuild is almost as much as the new ones.

I may have them rebuilt and keep them on the shelf..... or if someone is in the SF Bay Area and wants to go thru the rebuild process let me know.

New Part #'s for non lifted F250

Front 985-24-154
Rear 985-24-151

Got them at Shock Surplus - when ordered as a pair front and rear the price was great. Entered my email and got another $20 off.

Best price I could find and came with free shipping.... They shipped same day as I placed the order.

 

I have two comments.

if the shocks have a nitro refill valve...might be worth the time to check the pressure.

50K miles on the shock while in street use doesnt sound like they are at the end of the line to me.

I would clean them up and put them on craigslist and disclose the miles. someone will buy them.

 

Have them rebuilt. By the time you need them again they may be double the price.

Since 2019 they have gone up 25%.

 

I can have them rebuilt for $75 each plus shipping. All in with discounts paid $689 for the new ones. I do a lot of RV towing and the roads in CA are pretty bad.

Probably the last couple of thousand of miles I noticed that the ride was just not as good / compliant as before....

 

No refill values - I will give craigslist a try...

 

Don’t mean to highjack this thread although I do think it relates to OP’s original question. I also mostly tow trailers on the highway with my truck. Has 112k miles on the original shocks (they’re done!). Running stock size tires (18’s), stock suspension etc. How do the Fox 2.0’s compare to Bilstein, Rancho etc as far as ride quality and handling.

 

How did you get them for $689?

 

Check out this video in the link below. Only thing, If your truck is not lifted I think you would need the Bilstein 4600's

The FOX shocks are firm - which I prefer. I would guess that the Bilstein shocks are softer.

I checked my old receipts and I'm actually close to 60K / 4 years on the Fox's.

I also replaced the Ford stabilizer with the adjustable FOX one.

Shopped them on this site. Link is below.

Bought them in pairs and also signed up for the email contact which gave me another discount. Don't do the set of 4 - it actually is more expensive.

Do the front pair and the rear pair.

Best price I could find

How do you know when you need new shocks? Or is it obvious? I'm getting up to 45k miles on mine, but I can't tell if it needs new shocks, but when camping, about 25k miles of that, are with a 5k pound truck camper in the bed. As far as I can tell, everything is fine. Had an alignment not to long ago, and didn't need hardly any adjustment.

 

Good video, but his explanation of how one is stiffer than the other is a bit off. These are not position sensitive shocks, they are speed sensitive. So you have to think of the damping in terms of shaft speed, not shaft position. Fox is valved softer on the low speed and stiffer on high shaft speeds compared to Bilstein. So Fox may have more body roll or diving under braking as those are slow shaft speed situations, but more resistance to bottoming and control over bigger, faster hits. On my F450 it is already wide with heavy spring rates so it's really planted on slow shock speed maneuvers anyway. I wanted more bottoming resistance when loaded hitting uneven bridges and frost heaves so I went with Fox. If I was running say a F250 lightly loaded daily driver I would have done Bilsteins for street handling.

Fox 2.0 monotubes take a special nitrogen needle fill setup. When I get to 50k miles on them I plan to rebuild and while I'm at it drill and tap my own shrader valve in the bottom end for easier rebuilding. Disclosure: I have a shock servicing setup in my garage and DO NOT recommend disassembling or modifying your own shocks without the proper tools and knowledge!

 

Fox Shocks require regular maintenance, even with 100% street driving, 50K miles is the interval for replacing the seals & oil.

YUP - That is what they told me on the phone yesterday. Why am I replacing them?

In the last 1000 miles or so it seemed as if they are just not as "comfortable" - call me crazy ... but the new ones are on the way.

I may have the old ones rebuilt and but them on the shelf for the future....

 

Is your 450 stock height? If so would you mind sharing part numbers for the fox shocks. I replaced the factory shocks at 30k with Bilstein 5100's which are ok for now. I am the worst demographic as I go from unloaded daily driving to towing our 18k rv to a 20-25k equipment load. I'm looking for something to calm the bottoming out when loaded exactly as you described. The long wheel base of the 450 amplifies those hits when towing in my opinion. Thanks in advance.
