Performance Shock Reservoirs Explained - Filthy Motorsports

[@shirolee]

Finally, someone who explains well how remote reservoir shocks work! Thank you

[@Filthymotorsports]

Glad to hear it!

[@zahranshehadeh6585]

what a great video. this guy need a raise

[@maxgermasi3302]

I can say I finally found a very well explained video on the subject Good on ya nice videos I'll subscribe Cheers

[@Filthymotorsports]

Thank you for the feedback!

[@kevinsoui7947]

Who paused and subscribe within 10 seconds of this guy talking Subscribed! It’s refreshing to finally hear some people who know what they’re talking about. With science and knowledge and research backed up not some 12-year-old in a doctors coat trying to explain to me with a regurgitation of other idiots that don’t know what they’re talking about. Information or misinformation is a powerful thing.

[@philc6138]

As many folks have already said, great video and explanation on how a shock and reservoir work.

[@Filthymotorsports]

Thank you!

[@davidscott8926]

your explanation of the reservoir was a great help - thankyou, as I think with mine when I bought them, they had little to no nitrogen in them 😞

[@AlloffroadAu]

great review, I again learned something new

[@The-Vay-AADS]

this is excellent salesmanship, my respect & thanks for the showcase. :)

[@Filthymotorsports]

Thank you, so glad you enjoyed it!

[@dangerousfandango5943]

So is the resovior nipple just a air chuck nipple? The well have to carry a nitro tank with use to tune it ourselves on a dirt road? Dont some come with adjustable damping?

[@Filthymotorsports]

Yes, they are standard style schrader valves. And yes, changing the reservoir pressures is one way to fine tune a shock.

[@zombieqtr]

Ben, when speaking in regards to shocks that are not too lengthy, you would have to compensate for that by increasing the compression ? The longer the travel the softer it can be ?

[@JPRC]

Nice explanation

[@Filthymotorsports]

Thanks!

[@thebigempty_5792]

Land cruisers have been crossing The Australia Outback and going on Africa safaris for years with monotube shocks....but I guess I must have an Icon Stage 3 for mine because I off road a bit and camp on the weekends.

[@PaulPearson-q1o]

Does it matter which direction the remote reservoir is mounted? Thanks for sharing your knowledge?

[@ucbeyond7179]

this video was greatly explained but i was looking to build a sand rail and i was looking at suspension my type of terrain is usually just sand. I was looking at bypass shocks and i just got completely lost there never really worked with any type of suspension what do you recommend its usually very whoopy around where i go and i was looking at coil overs for the front

[@terminalfrost3358]

Good job explaining the effects of the nitrogen pressure on the shock valving. I needed that answer!!!

[@sweetaznboi209]

Nice ! I have a suspension that I order and it’s with King shocks . I can’t wait to see how it rides !

[@MH-67]

Great video sir; very informative

[@PeterHartman1]

Great video. Thanks for explaining.

[@Filthymotorsports]

Cheers!

[@HOOMARKTUBE]

Nice demo and one thing I don't understand is the reservoir part, the valve let the nitrogen get to the oil side when the shaft is compressing, so my question is the nitrogen will mix to the oil in the reservoir but also mix to the oil in the main shock as well ?

[@Filthymotorsports]

The IFP in the reservoir separates the nitrogen from the oil at all times.

[@pfdlegaspi1]

Awesome video, very informative. Question: How often should I recharge the Shocks with nitrogen? Should it be done annually or as needed? I currently run ICON 2.5 w/ res. & CDC valve on my Tacoma.

[@Filthymotorsports]

If the shocks are in good condition and the Scharade valve cores are tight, they should never leak. I've had some shocks hold good pressure for over 10 years.

[@martinkorjus7607]

every modern shock absorber has nitrogen in it. I have met original shockabsorbers 30 years old, that stil holds nitrogen. You can tell it by, wathing does rod comed out by itself from comressed stadium or not. If it does, seal is ok and nitrogen still there.

[@amadorbimmen]

You say start at 150 psi, is that with the vehicle on the ground or off??

[@Filthymotorsports]

150 PSI fully extended (off-the ground) or 160-170 PSI at ride height :)

[@revise7105]

In my case, I can only find Kings without the reservoir for my 2WD 06 f150 but they have them available for 4WD, would those still be able to bolt on?

[@Filthymotorsports]

Those particular coilovers have internal IFPs so the "reservoir" is built into the shock. This only works for shocks with very little travel.

[@mikesullivan121]

I have a set of fox 2.5 coilovers with reservoirs in my truck and the hose to resi's has split apart. I'm assuming the fluid in the main body will now have aeration without the nitrogen pressure and could likely just leak out of the break in the hose with compression and expansion since it obviously can't reach the resi. Correct?..would there be nitrogen still charged in the reservoir since the piston separates them? Just wondering what the correct repair procedure would be to get it working properly again?. Thanks

[@Filthymotorsports]

A split reservoir hose will leak oil but should not leak nitrogen. In any case, the shock needs to be completely opened to repair the hose correctly and then have it properly filled with oil.

[@franciscoherrera8256]

I got ram lifted and just to be sure I can get the right shocks I need regular nitrogen or I need does with the reservoir ? Thank you!

[@marcintopor7710]

Do you have to rebuild the reservoirs or what kind of Maintenance do you have to do to them

[@Filthymotorsports]

Generally not, unless reservoir pressure is lost and the end cap gets pulled into the cylinder along with some dirt, dust, or grass. Luckily, if caught soon enough, it's easy to clean them and change the o-rings if needed. Great question!

[@rusmadichen868]

Hi Ben, great engineering explanations. I just learned how reservoir shocks work. What is the range of psi nitrogen pressure for adjustable reservoir King Shock?

[@Filthymotorsports]

So glad to hear it! Most applications require 150-200 PSI.

[@VAJOLOMA13]

I have a 6" Pro Comp coil over lift kit. Can I add on a reservoir with out having to remove and of the lift kit?

[@Filthymotorsports]

The shock would need to be opened to properly add a reservoir.

[@texasstealth1911]

So if I get bilstein 5160 resovior shocks are they ready to go or do I need to tune them?

[@Filthymotorsports]

Those are built to go right out of the box.

[@JordanKaczmarczyk]

Would you say that king IFP 2.0s would make a great DD with some but limited capabilites offroad on two tracks and minor trails low speed?

[@GerbilIV]

I have a 2003 Ford F-250 7.3L that tows some and sees light off-road use. It's ride is rather stiff - what shock would you recommend to give it a somewhat better ride? No reservoir I assume? Bilsteins? Fox?

[@Filthymotorsports]

This is the King shock kit we offer for the early Super Duty: www.filthymotorsports.com/King_Super_Duty_Shocks_p/king-superduty.htm

Of course they would push king shocks $$$$🤔

[@Bu3o.R]

Thanks for your videos, never found it scientific and well understood better than watching your videos. Now, I come from a country where san dunes are literally behind my house. Can I know what tyre pressure fits in the calculation to result in a proper shock rebound?

[@Filthymotorsports]

Thanks for the feedback, glad you liked it! While the reservoir pressure does force the shock to extend, it is generally not enough to account for. The rebound valving should be matched to your springs and vehicle weight.

[@95BerrySt]

Thanks for the video, very helpful. I have a question I am looking at a Bilstein kit for my 2016 RAM 2500, Bilstein recommends the 5162 kit for the front and 5100 for the rear. My question is if they have reservoirs in the front wouldn't I also want them in the rear?

[@Filthymotorsports]

It's not so much about the reservoir as it is the IFP (internal floating piston) so as long as the shocks you get have an IFP to separate the nitrogen from the oil, the shocks will perform much better than a generic emulsion shock. Hope that helps!

[@andycampbell3599]

@@Filthymotorsports how do you tell the difference?

[@derecknielsen1430]

Andy Campbell you can tell the difference because when you are shopping for shocks online it will say “IFP” in the description of the shock. Usually it’s on a 2.0 shock. Hope that helps

[@richardcote9663]

What's your thoughts on bladder vs piston in the reservoir? Does a bladder allow nitrogen contamination of the oil?

[@potatofarmer6647]

When you add more presssure does it make the ride harder or does it smooth it out more?

[@Filthymotorsports]

That depends on how the shocks are valved but in general, a shock with too little pressure will usually ride "harsher" because the shock valving is not doing work so adding pressure will improve the ride. Alternatively, a shock with too much reservoir pressure will typically feel far too firm because the shock is not only using all of it's valving but is now also trying to compress the nitrogen during compression (like a bump stop).

[@alstanlewis3480]

What kind of a shock would be more suitable for a SAE Baja Buggy??

[@Filthymotorsports]

Due to the ultra light weight of those vehicles, 2.0 air shocks have given us the best results: www.filthymotorsports.com/King_Air_Shocks_p/king-air.htm

[@ashman25]

I have custom black King Coilovers front and rear on a Jeep JK. I had oil leaking out of the extra reservoir when I drained out the Nitrogen. Is the extra reservoir seal blown?

[@Filthymotorsports]

Hard to tell, how many miles are on the shocks? Did the reservoirs lose pressure at any point?

[@ashman25]

@@Filthymotorsports 50,000 miles probably on those shocks. Yes one in the rear had zero PSI so i filled it up. I checked it the next day and on half of the PSI from the day before. I drained it to zero and oil started draining out of the remote reservoir.

[@eaboatnuts76]

I have a 2000 excursion with the 7.3. daily driver that I tow with on occasion. Due to weight of the front I seem to burn up shocks when I adjust them to the ride quality that I prefer going down the road. Would you recommend dual shocks or would one reservoir shock be stiff enough and last?

[@elmeradams8781]

[@P.M.O.S.69]

Why is nitrogen used? Is there a kit that is used to adjust the pressure?

[@Misswaipahu]

can I put resevoir on front and smooth body shocks without reservoir on back? it's it's a jeep unlimited

[@martinschilpp3685]

In a monoshock without outside reservoirs there is also a seperator piston, so no bubbles

[@markbenoit]

Where do you want the piston when assembling shock?

[@Filthymotorsports]

In short, you remove the valve core, push it towards the hose end and then when you fill the cylinder with oil and insert the piston assembly it will push about an inch or so of oil into the reservoir to set the IFP. More details here: www.filthymotorsports.com/kingrebuild

[@bubbasdually]

Thats not always true though, there are IFP non reservoired shocks available.

I'm happy to help! The best way to start is by sending me an email: [e-mail]

[@FerreroCollection]

Does the reservoir need to be mounted upright?

[@Filthymotorsports]

Great question, no, it can be mounted in any position.

[@FerreroCollection]

perfect, thanks!

[@jorgebacasaavedra958]

me gustaria un video subtitulado en español o italiano

[@rsstnnr76]

Why don't they just make the shock fatter to hold the additional fluid?

[@Filthymotorsports]

Great question! Making the shock longer would also allow for an IFP inside the cylinder (the 2.0 Jeep JK shocks are built this way), however, these shocks are already massive to begin with so a remote reservoir tends to keep the cylinder sizes reasonable.

[@shehzadhamza6582]

bp51 vs dobinsons mrr. Which one to go as kings is out of budget for me.

[@Filthymotorsports]

From what I gather, the Dobinsons are just generic monotube shocks with a fancy paint job. Why not just stick with the basic OME shocks? They worked great on my 80 series for $70-90 a piece.

[@kevinsoui7947]

Makes me wonder kind of why other shocks don’t have this reservoir on it? Maybe they were last longer? Hell what do I know?

[@robertjustin1291]

This dude is Gangster

[@Filthymotorsports]

Word.

[@christopherwinn180]

So it's essentially a fancy built air shock?

[@Filthymotorsports]

Good question. An air shock (or nitrogen shock) is designed to support the weight of the vehicle and has a much larger shaft for that reason. And due to the very high pressures they see, a reservoir wouldn't be reliable so they can only be built as emulsion shocks where the nitrogen is in the same chamber as the oil. Reservoirs are only found on smoothie, coilover, and bypass shocks for more controlled damping. Hope that helps!

[@goskidmark]

Nitrogen.

[@johntowe4371]

As you say, High performance, that’s the key.... people who go camping, touring, weekend off roading, do they need a high performance suspension... No they do not, you can do that with a standard suspension, but if you want to up the stakes, Just buy a good brand, strong, normal type system and save your money..... so much marketing bull shit out there 👍
