Secondary Shock

[mrtifftiff]

Is there a mechanical advantage with a secondary shock system like Icon's S2 modular system? What is the purpose of bolting the S2 to the frame? That's quite a bit of flair, 37 pieces no doubt, but if the only thing it does is increase oil volume for heat dissipation, 15 pieces will do just fine for me.

That's basically it, along with some additional damping. If you aren't overheating your current shocks, and don't desire to push them further, then you probably don't need a dual shock setup.

Increased damping ability and increased control going fast. Additionally it allows you to run a bypass shock in the secondary position, which is position-sensitive (built in bump zone) and has independently adjustable rebound and compression. I've been running the S2 since June, and [MENTION=74569]SOcalTRAIL[/MENTION] has been running a total chaos dual setup for much longer. The cost is high, and the complexity is too much for many, but man does it perform well in those areas where you can run with a little speed! Check out my blog for my install, and [MENTION=74569]SOcalTRAIL[/MENTION] has a build thread.

[MENTION=51030]joneseyyy[/MENTION] I've been on the fence with this s2 system paired with omega bypass and your little synopsis is really making it make sense to me.

There is NO WAY you would be able to overheat a coilover with a reservoir with the amount of travel that is available with the 4Runner, even if you are at speed. Long travel? Absolutely. I can appreciate the desire to have it and the theory behind it, but if you somehow managed to overheat a remote reservoired coilover, not only are you magic - but your truck needs to take a diet.

I agree, it's cool and it makes your pen** bigger but with stock travel, non-racing duties it's way overkill. I've talked a lot about this with a good friend and former co driver in the Donahoe Tacoma that did a series of the Score races, and he also agrees it's over kill for stock travel.
I'd spend the money on shock tuning..
My .02$

 

[RG79]

Ya, I was thinking more bout it yesterday. I believe the money could be better spent on some 5.29's or 4.88's

No 5.29 available for the 8.2 rear diff.

So what exactly is the advantage of dual, triple , ect shock set ups vs. thicker diameter coilovers or a built bypass shock?

I will say when I had my Tundra with Camburg LT having bypass shocks was AMAZING, but then again I was going fast through mainly flat dry desert lake beds. Now I am doing trails that really don't have a lot of wide open places to go fast, so justifying buying the bypass shocks is tough. I already have the ICON LCA with the mounting tab but just don't know if I can come to terms with paying almost $1200-1300 for a bypass shock and another $500-600 for the shock hoop mount. It does look badass indeed no doubt but it's a lot of $$$ for something that most T4R owners don't really need.

It's not about overheating it's about gaining additional dampening. When I take my T4R in the dirt I am on the bump stops all the time even with small hits and with my cdcv icons tuned to 10. A second shock would provide the additional dampening needed and also provide better control

Yes, it's definitely not a need. let's face it everything we do here is a WANT right??? That being said I do think the Icon Omegas are worth all the $ that they charge. I have a set in the rear and they outperform my fronts

If your primary shock can't handle you bounding around then your shock isn't valved properly.

My shocks are valved perfectly. I just drive the shit out of all my cars to the point a secondary shock would prove itself useful. Bounding around, really?

[marshal]

hey if thats what you want to believe thats fine, but physics says a single shock is more than capable of handling the amount of travel our suspension offers

 

[Rubberdown]

Hey that's what I believe too. Do my kings work great? YES!!! Would I like to run a bypass second shock? Definately. Can I afford to? My wife says no. I do need the spindle gussets though.

It's valving AND volume. You could have your shocks tuned perfectly but if you don't have enough piston area to properly dampen the hit AND the proper volume to absorb the heat loads caused by friction then you will either have to slow down or have a failure.
Dual shocks and remote reservoirs are nothing more than a work around due to space constraints. The proper (and easiest and simplest) way is to just use one shock that is sized and valved correctly. Yes they are out there.
The band aid approach is to add another shock. They might look "cool" to some but to others they look like you couldn't figure out how to make it work with one shock.
With that said sometimes there is not enough space to install a properly sized shock and remote reservoirs are a necessity and in worst case a dual shock might be the only answer.
If you are driving a production 4Runner so hard that a top of the line King can't handle the abuse then you need to trade it and get something else because you have the wrong vehicle.

Yep all day long [MENTION=104049]marshal[/MENTION].
