do i realy need tripple bypasses

[coolcruiserfj40]

hey everyone im setting up my fj40 landcruiser for the rocks with 4link front and rear with king coilovers and tripple bypasses and a bunch of people have been saying that im stupid and will never notice the difference of the bypasses enless im doing 120 mph, do any of you guys have any thoughts on this? thanks!

Yes your wasting your money , bia pass shocks are for high speed . and coil overs are a waste also for rocks you should use air shocks .

[ntsqd]

Air shocks have a definite upper weight limit that is pretty low. An FJ's weight isn't exactly in the rock buggy catagory. I'd talk to the damper vendor about which to use.

I can see where a by-pass damper might have some application in crawling, but you'd have to be at the point where you're looking for that fine little advantage over your competition.

If you spend time on Pirate 4x4 you might have heard of Tinbender (Rob Park). He is my lead fab guy in my high dezert shop. Rob and I have talked lots about this and we both feel that much over a simpel 2' or 2.5" coil over is a waste of money. Especally bump stops. Bumps actally limit the last 4" of up travel and really take away more that they add to the equation.

i was watching RIDES list night and they had the Peterskin 4wheel journey/jamboree thing on there, anyways....one of the rock crawlers had 2.5" king air bumps on it. LOL

I dont know but I would guess that there going for the bling effect.

"I dont care what it costs or if it even works. I want it cuz it looks cool".

If you already have the by-pass shocks on it you could actually put very light velocity valving in the by-pass and coil over shocks. By-pass shocks are POSITION SENSITIVE. I could see were in instances this could be a benefit. Like bouncing over really rough boulder inclines were you would need to be in the throttle just to make it up and over. If you have them, keep them. There is nothing the matter with adjustability. I don't see a problem with it especially on a leaf sprung deal. Of course 3" by-pass shocks would be a bit over kill.

Good chance that was my K5 with the 2.5" bumps on the Ultimate Adventure, so....
If bumpstops are to soften impacts and you have a rig with 55% or more front weight, guess where there's a good place for quality bumpstops?
Nice thing about a 2.5" bump is that you can run a pretty low air pressure so you get a gradual engagement which keeps them from getting annoying on the trail and doesn't upset the suspension when they engage. They may (depending on where they're mounted) keep you from using the last couple inches of shock travel but in a rig with 8" of bump travel, this isn't a killer. If they're set inside the shock a little, you' won't lose any articulation at all. But since this isn't rock-crawling.com....

How does this translate to using a bypass shock on the trail? The external adjustment could be nice, maybe you want to have more rebound damping at the end of the travel to keep the front end from pushing away (transient reaction only), this could be tuned with a specific tube. Maybe you want to go play fast with the same rig, I had my 2.5 coilovers pretty hot at one point last weekend on a "crawling" trip, if we had gone much farther some more damping would have been nice.

So I agree with the theory that it won't hurt anything but the pocket and may be fun to play with.

ya ive met and talked to rob before i was hoping he could help me out with setting my shocks up but it sounds like hes going outa town for a while, he was saying i could valve my coilovers realy lightly and use the bypasses heavy or something along those lines

[coolcruiserfj40]

i already have the bypass and coilovers, i cant realy run airshocks they will get way to hot to fast i plan to drive this on the street some and im not trying to make this a prerunner but i would like to be able to launch it at pismo or fly around J.V

Y'know, I wonder if we can convince everyone that Bypass shocks are the next :bling: thing since the externally adjustable RS9000s... and they'll all start shelling out $500 for bypass shocks instead of $100 for an RS9000, and they'll bring the price down through volume.. :D

or raise the price since there will be a demand that will need to be met ;)

Or Fabtech, Pro Comp, Skyjacking/Skyking, Rancho, and Edelbrock might start making "affordable bypasses" for their kits. Sorta like how the chromed Kings and reservoirs to all of 4 shocks per wheel under a disco truck is the new bling standard. Maybe Bilstein will have a bypass version of the 5100, like the reservoir 5150. Brings new meaning to "disco tech".

On the other hand, this thread did open my eyes to uses of valving/air bumps in legitimate 4x4/rock crawling apps.

I'm planning on using coilovers and bypasses on my next one too.

What is the consensus on air bumps stops with bypasses? I've talked to a few people and get different information. I've been told no need to run air bumps if I set up the bypasses correctly. Thoughts on this?

This will be on a 50/50 f-r weight ratio buggy with 750lb sprung weight per corner.

Any advice on this would be great.

I talked to Brett King about this very thing. He said; "They are not required but every extra bit helps."

[coolcruiserfj40]

i bought them and my plan was so i could jump it and use the last tube as my bump stops
