Rear bypass shocks

I hit up drkdss hes a wealth of knowledge

Yes! He's a good guy!

Good points. I've always been told that the kings and fox are progressive.

Ya just learned that the 8100s are linear because they are bypasses. Could be a very good option. Just watched the shock surplus video on the bilsteins. They seem pretty awesome. Should I be really saving for long travel?

Talk about a huge question!

HondaTitan thinks so. I dunno.

It all depends on use. If HondaTitan wants to be the guinea pig on the 2", I would love to learn from him. I guess we are some of the few people who can use LT. And I can benefit from it on harder trails as well.

But I am very concerned with race style components in terms of maintenance, noise, and harshness until the 4Runner remains the do-it-all family wagon.

Maybe we get a Rivian in a few years and then...

After a closer look, the tundra TRD pro wouldn't fit. The problem is the reservoir being hard mounted on the bottom. Tundra and taco use a lower mounting post that is lateral to the chassis and the 4runner is longitudinal. Basically they're 90* from each other. So the reservoir on the tundra shock would interfere with the lower rear control arms. I'm sure a solution could be fabricated but it's not worth the effort. They're not that much different from the 4runner OEM fox bypasses that will just bolt on.

There's just not that much travel to work with so having an inch or two of softer valving from a bypass might not do much more than a flutter stack would in a regular monotube or even a good valving set in a twin tube. Without a side by side test drive it's really hard to make even a subjective comparison. It's easy to get carried away with a lot of shiny hardware that doesn't translate to better performance.

He installed the trd pros or the 8100s?

The TRD Pro Fox's with internal bypass.

And I would say yes to saving up for long travel if you like going faster in the 4R. Very worth it for higher speed driving.

To do long travel right, you're going to want to run:
- coilovers and a bypass up front
- air bumps all around
- califab's 3 link in the rear (see their black GX with long travel)
- fiberglass up front
- wheel spacers in the rear to reduce difference in width compared with the front's increase
- must run extended front cv axle shafts to retain functional 4WD
- if you'd want to keep sway bars they'd need modified end links, or go full custom, but that's $$$.
- most kits come with extended tie rod adjusters, but going with all new billet tie rods with heims is best for handling the harder, more frequent impacts.
- limit straps since shocks at this level aren't meant to be droop limiters

List goes on and on, but again doing right affords you some rad abilities and amazing experiences.

Bummer also seems like they are sometimes hard to come by. I was reading they are rebuild able though and could take a tune. That's pretty cool stuff.

Ya that seems like a serious investment.

I think maximizing a mid travel setup might be the best way to go and keep it fun. Perhaps do some bypasses in the rear and adding some hydro bumps all the way around would be good. Also might look into the stock length lowers and possibly squeezing a bypass in there for extra damping.

I've noticed the state rangers at ocotillo can bomb around everywhere at pretty good speed with just a mid travel setup. Those cars have to run all winter long. Wondering if it's just an aggressive tune.

Ya I don't want all the maintenance of long travel. I think I'll stay in my lane ha. I think maximizing mid travel might be fun.

Camburg just came out with a long travel kit that utilizes oem performance shocks but it's still $4k and some fab work.

I bomb pretty hard with my simple setup of 6112's w/650lb spring, Dirt King UCA's, Ironman 4x4 HD rear 2" springs, Ironman FCP's (had 5160's but they're too lightly valved for the HD springs), and Durobumps all around.

With actual performance shocks all around tuned right and air bumps, you could prob be just fine out there. Won't be trophy truckin' through the big stuff, but there's plenty of desert out there without 3ft whoops.

Do you ever go to Superstition? There's a section that goes from the train track road to pole line that is a ton of fun and good for mid travel trucks.

theyre working on the kits for KDSS as well from what it sounds like. Whats cool is you can upgrade to it whenever. instead of dropping 10k all at once. spend 3k on the front end, later on add the camburg kit. i'm hoping to buy it this year at some point.

this x2....we kept up with stock raptors. at no point were we the ones holding the group back except on the highway lol. I'm sure they had a nice plush drive and we were mobbing but still.

No kidding. I don't normally bottom out the front (same as yours) over bumps even if there is a tiny air gap under the front wheels.

However, what bottoms out the front if I am not careful are the sharp, narrow drainages that run across, depending on the shape and size.

Especially if there is a dip followed by a sharp rise. It is like hitting a curb full front essentially.

Except for those, I can go fast enough to worry that hitting a rock can have nasty consequences.

And how about cows??? (they were not even sore, 90mph, but that's a Geiser chromoly cage and a properly prepped race car with all the safety features).

Ya I can agree with that.

Never been to superstition but I need to.

I think a confident setup and knowing how to drive does wonders. That's rad you were able to keep up with raptors.

I feel my shocks are the best they can be. I've had them tuned twice. First time at accutune then I went to dialed shock prep.

we need a tune for the fronts. wayyyyy too soft lol duro bumps got a workout.

So is X-REAS basically a system that uses the opposite corner shock as a “reservoir” for the one being compressed? (sharing fluid) [emoji23]

For the kings?

si. theyre just off the shelf ones.

Good question. I've only seen people removing x-reas
