Rebuild Your FOX TRD Pro Internal Bypass Shocks on the Tacoma / 4Runner / Tundra

[@DirtMcgirt2506]

Incredibly informative video! Hope to see you guys rebuild the front shock soon!

[@ShockSurplus]

The process is the basically the same but with a spring so you are not missing much LOL

[@SrBuho01]

I have a question, has anyone experienced Shocks squeaking ? I have a trd pro Tacoma 2023 and it started squeaking at 6k miles, truly annoying. Only squeaks in the morning what could that mean ? Dirt on shaft ? Or bad shocks ?

[@MooseDitty17]

How would you rate TRD Pro suspension against aftermarket options. I want to gain ride height and travel, so Im looking at the Dobinsons IMS. I have no need for Resi suspension...

[@mralabdulgader]

Thanks for the excellent informative video. Will this suspension kit fit a 2014 FJ cruiser?

[@ShockSurplus]

Yup just needs to be from a 4Runner

[@bearysh]

@@ShockSurplusdoes the 4r kit fit the tacos?

[@TheCortez714]

@bearysh the fronts will fit, but the rear suspension is slightly different because of the bottom bushings. You may run into issues there.

[@Carnal0429]

How do you charge nitrogen? Is there a Schaefer valve inside or a needle?

[@ShockSurplus]

The reservoirs have a shrader valve on the end

[@NoobsDelRC]

Hey, I have a question, right? These shock absorbers are in good condition. First, they don't have to be wet and second, when you compress the shock absorber, it has to expand the instant you compress it, right?

[@ShockSurplus]

It sounds like you might be trying to determine if a set of shocks you have is good or not? So yes, if it is not leaking and if a gas shock extends back nearly immediately after being compressed, that is a good sign the shock is at least somewhat functioning. With that said, that does not necessarily mean a shock is in optimal working order or may not need to be serviced if serviceable. Shock oil degrades overtime and through heat cycles, and although if a shock extends the outermost seals are holding, it does not necessarily mean that the nitrogen that causes the shock to do that is in the right place and has not slipped passed the IFP.

[@fullreleaseblake]

Any tips on how to get the seal head unscrewed from the inner tube? I've got the external ring off, but can't for the life of me get the threads to break free with regards to the inner threads of the seal head (it's rotating the bypass tube piggy back arm and all connected to it on the opposite end of the shock body...)

[@ShockSurplus]

The seal heads on these really like to seize to the bypass tubes so it does take a fair amount of force to get them off. If there is any nitrogen that made it passed the IFP it can be almost impossible to get off so it is good to leave the bleeds open until oil starts draining. From there if it still will not come apart you often have to bite the bullet and let the body unthread and separate, so you can physically grab the bypass sleeve to make it easier to get the seal head off.

[@dallenellsworth9080]

What is the ifp depth for the fronts and rears on these? I've been looking everywhere and can't find it.... Thanks

Can you make a video how to rebuild them DIY

[@ShockSurplus]

We'll queue up an instructional video next time we have some in to rebuild

[@Xeros921]

@@ShockSurplus thank you because I would love to DIY mine and not have to send it to fox

[@TheCortez714]

​@Xeros921 I plan on rebuilding mine on my own. I'll do a video, and I'll try to record as much detail as possible.

[@Carnal0429]

@@TheCortez714 planning on rebuilding mine as well. Looking forward to it.

[@Xeros921]

@@TheCortez714 that would be great !

[@TheCortez714]

This suspension is better than the fox 2.5. The suspension is much softer, which gives a much better ride. And its still available

[@ShockSurplus]

Well they are an internal bypass which the off the shelf Fox 2.5s for a Toyota are not, but there are plenty of position senstive shocks from Bilstien 8112s to even OME BP51s that are leagues better than these stock TRF PROs

[@XDgamer-lk8nf]

Can you get the decals stickers for fox 🦊 on a 23 trd pro

[@ShockSurplus]

Not sure if we can

[@TheCortez714]

Fox does not offer straight decals for the suspension. They may replace them if you send your suspension to them for rebuilding. Your best bet is to take them off and take them to an independent decal shop.

[@XDgamer-lk8nf]

@@TheCortez714 thanks brotha

[@Thexhunkxlaxsb]

Do they have a part number visible on the outside? Im looking for a second hand pair for a tundra

[@ShockSurplus]

Good question, we dont have these here at the moment so we're not sure about the visible part numbers

[@kingrichard_1093]

I need new shocks on a 96 F250. What is good for hauling but have comfortability?

[@ShockSurplus]

If it is stock height Bilstein 4600s would be a great choice. Otherwise if it has a lift a Bilstein 5100 or 5125 would be a killer option as well.

[@kingrichard_1093]

⁠​⁠​⁠@@ShockSurplus It does have a 4 inch lift, so either 5100 or 5125 are good? And which one has more comfortability. Thanks for replying, been stressing on it since my rear shocks are broken and don’t know much about it.

[@ShockSurplus]

If it i 2WD that would be 5100s but if it is 4WD it will be 5125s. Both are the same 46mm monotube design, the shocks Bilstein recommends for the 4WD happen to also be used in their universal catalog as well so they are called the 5125s.

Can you share where to find the rebuilt kit.

Can you make it better.

[@ShockSurplus]

As in change the tuning? We could

[@pfan760]

@@ShockSurplus you guys can change the tuning on the TRD Pro fox shocks? that would be sickkk

[@canalesivany]

How many miles they started leaking?

[@ShockSurplus]

If I am not mistaken these had about 70k miles on them when they came in, but from the looks of things, the leak definitely was not new. Just like the rest of Fox shocks, these should probably serviced at around the 50k mark with strictly street use and sooner if they see any dirt miles.

[@canalesivany]

@@ShockSurplus wow. When do I need to replace my 6112 on my Tacoma?

[@ShockSurplus]

6112s will easily go 60-100k miles or more with ease. They use more traditional seals, so they can not take the high temps a Fox or other race level seal will survive , but since they are a softer material they do not wear as fast under more normal use. With that said it takes a heavy dose of masochism to really get the 6112s hot enough for complete failure. They are tuned to be a more Trail/Daily Driver shock and being a 2.6" diameter body with a ton of oil and gas, they have more capacity for heat dissipation than they have support for absolutely sending it. Basically you would have to be smacking the daylights out of your bump stops through whoops for a lot longer than the average person could handle without a big bill with your chiropractor.
