fox 2.5 DSC issues?

They really go hand in hand. You need to have the proper spring rate for the weight of your vehicle, then the valving inside the shocks provide all the ride comfort. This ride comfort would be from small cracks in the road, potholes, washboard road, big whoops etc. Incorrect spring rates can lead to other issues that cannot be fixed with tuning. Example: too soft of a spring, you will blow through the valving to bottom out the vehicle. Compression adjuster can only do so much to help control that. Same for the opposite with too stiff of a spring. Shock isnt moving enough and valving isn't doing enough work. However, for leaf springs thats tough since driving around with an empty bed will also feel a bit firm until it's loaded.

Also, thanks for all the mentions in this thread. We've gotten a lot of great feedback over the years with our tuning, and on a wide variety of vehicles. We've never been a fan of off the shelf shocks, especially since these higher end shocks are designed to be customized. It is totally worth getting your shocks tuned before considering the idea of selling them and going to another brand/style. There is a lot that goes into tuning and can really make a difference.

 

Them are purdy

 

that's good information.. I have no added weight on my truck and the stock spring the fox 2.5 come in.. Would you guys be able to tune the shocks to be softer on road? I feel like the DSC softest setting is pretty firm still...

 

FWIW, those aluminum resi clamps are a pain to install on the front. I mean once they’re on, you’ll likely never touch them again, but it takes a few tries to make sure you don’t crossthread the tiny bolts while you fight the hose and clock the resi fittings.

 

Short answer is yes, we can make the shocks more comfortable. We would just want to review the truck and your expectations before we consider revalving them for you. Happy to go over that with you if you would like, just send over a message.

 

I am a little late to this thread but I've been experiencing the exact same issue with Fox 2.5 DSC Fox shocks tuned by Accutune for two years now. The internet and an unscrupulous mechanic took me for a frikken ride figuring it out, but then I saw this video and it all clicked. I reached out to Accutune to ask about revalving but honestly the ride quality has been so bad that nothing makes me think they can do anything to the Fox shocks to make them ride on the road comfortably. I get one free revalving included with purchase, but I didnt know it was the valves and spent two years chasing the problem, so now the shocks have to be rebuilt? the cost of rebuilding the shocks, even with a free revalve, is half the price of replacing them with Bilstein 6112/5160s. I'm very tempted to throw the Fox in the trash (or sell them to another sucker on Fb) because I know the Bilsteins will ride smooth on the freeway. I've been frustrated to tears about this entire experience numerous times - the ride quality is painfully jarring to my lower back and its been endless arguments - with my mechanic (LOL who never actually test drove the truck), with the internet, with my friends, I even recorded a bunch of inside/outside videos showing the truck bouncing down the street but everyone said "it rides like a truck". I also tried reaching out to Fox and I got sent to voicemail hell. If this is how a modern Tacoma rides, I will gladly trade it in for a Jeep. The stupid part is that I have never used the performance of the Fox shocks. Not once. The ride quality is so bad that I won't drive on the freeway long enough to get to the country. I really wish I had gone with Kings or Bilstein. Maybe Fox was good back in the day, but I wouldn't purchase their product again.

 

Given it’s your first post it does seem a little sketch but giving benefit of the doubt here. Few questions to help.

How do you know it’s the shocks? How do you know the Bilstein will be smooth? How is the ride bad? What tire are you running? How much additional weight does your truck have?

 

I believe its the shocks because i have replaced the UCAs and leaf springs at least once. Right now I have builtright UCA and 14" 700lb spring in the front, cranked down approximately 24 threads on the drivers side. Originally I had fox 13" 600lb springs (before the bumper and armor) and still had the bounciness issue, regardless of preload. The ride quality was unaffected by replaced the UCA or leaf springs as well. I have also changed tires and wheels as well - I began with 255/75r17 BFG ko2 on a 26lb American Racing wheel, and now I have 285/75r17 Toyo AT3s on FNwheel Six Shooters. They are set to 30psi, the rear Fox DSC has the LSC set to wide open and HSC set to 2, the front has the LSC set to 2 and the HSC set to 3. My truck has a significant amount of additional weight, (although all of the issues were there from the first day of the Fox installation). I currently have a Body Armor Hiline bumper and Warn 10k winch w/ synthetic line, Full RCI skid plate package, dual battery with optima yellowtops, body armor revo rock sliders, a bel-air camper (approximately 550lb) and a rigid armor rear tire carrier. It should add up to around 1200lbs additional weight. I also added 250lb of water to the rear as a test, and it helps with the bounciness some, but its clear that its not really addressing the underlying problem. With these settings and with the extra weight, the truck is not physically painful to drive like it was, but its very bouncy and doesnt seem to handle correctly. I am at an impasse - while I believe Bilstein would ride better on the street, I think specific circumstances (concrete freeway sections in SoCal) may be worse, and also I don't think the Bilsteins would handle nearly as well. If the Fox could be revalved so they're softer, but still retain the performance characteristics I would be interested, but that feels like asking a lot.

 

What are measurements from center of front hub to fender? You have quite a bit of weight on there. I assume your tires are LT.

 

Send them back to Accutune for another re-valve. I wonder if you could drop to a 650lbs spring and adjust the valving/compression/rebound to compensate?

 

I'm calling bullshit on all of the above.

 

+1

 

c-rated Toyo AT3, rated for 2835lb each. Height from center of hub to fender is approximately 23"

What evidence would you like to see? https://www.youtube.com/watch?v=9nIefc8g01U there is an in-cab recording at Fiesta Island in San Diego. The pavement there is perfectly flat.As you can see from watching the stuff in the cab, the truck is bouncing around like an unladen dump truck.

 

You're kidding me with that video... Right?

This has got to be some sort of troll post

 

:doh: I forgot you're an idiot
get out troll
EDIT

just checked your build profile.. I dont need advice from you. Please leave the thread.

 

Things that are obvious to me.

A) If you don't even know how to work or your own stuff, you don't really have a valid opinion on ride quality.

There's a whole bunch of different things that effect ride quality that aren't the shocks. In fact the shocks are one of the least likely to effect the ride quality.
Front for example: coil rate, preload are 2 things that will have a much larger effect on ride quality than the coil overs.
Rear: Leaf springs play a much bigger role in ride quality than shocks.

B) If you don't know how to work on the shit yourself... and you take it to a mechanic that doesn't even road test it... and then you begin throwing money at it on the advise of your piss poor mechanic... then you're an idiot.

C) You categorically DID NOT get sent to "voice mail hell" by Fox Customer Service... that's just a lie.

 

LMFAO... You "don't need advise" from me.

But you'll take advise from a mechanic that can't even be bothered to road test your truck.

Ya... that checks out

 

so you're going to insult me without any proof whatsoever, and then spit out platitudes after I listed the very specific items I've purchased to address the issue. Cool!
I could show you the screenshot of the phone call to Fox on Monday morning, but you dont want evidence. You want to yell at a stranger because they're having an experience that doesn't fit into your extraordinarily small preconceptions.
If there is anyone who actually owns Fox 2.5 DSC shocks and is experiencing the same issue, per the actual thread, I would be very interested in your opinion.
El Taco Diablo you have nothing to offer, so I reiterate again, please leave the thread

 

Bro... I've spoken to Fox on a NUMBER of occasions.

I've spoken to the Vice President of sales and marketing for North America.

I've spent over an hour on the phone with their tech support fixing a problem that wasn't even theirs to begin with.

Maybe you're impatient... maybe your straight up lying. But from the few posts you've made, I can tell you have no fucking clue what you're talking about, you're seeking advise from a mechanic that has no fucking clue what he's talking about. And you are attributing problems to things that just plain don't make any fucking sense.

Like... changing UCAs expecting to solve a ride quality issue. Who was the fucking knitwit that came up with that bright idea? You? or your mechanic?
