Brenthel long travel install

[Macman]

Yeah I can imagine, I have always been away for the runs with Military courses all over the prairies, hoping to also get to one before my posting to the east coast at the end of the summer.

Does that $10,000 include shipping etc and is that CDN?

Hoping to make it out that way for a run before fall.

Hoping to sort the rear end out better as well before a run !

It's not even in the same league as the front now... It's borderline dangerous how easily one can drive past the rears capability and the front end is not even starting to work hard.

That's what i m worry about, the front end needs more speed to keep the damping zone and spring rate to soften. The best thing is to have a bump stop already.
wait for the rogue cantilever or any undersprung bedcage.
Otherwise you should be careful of bending the frame at the rear, on those ohh shit moments.

Around $11,500 shipped in canadian funds.

You're talking crazy talk again.
More speed does not "keep the damping zone" or soften spring rates.
More speed does effect the velocity sensitive piston heads, and cause the shim stack to open progressively as shaft speeds increase.

The brenthel tuning on the kings actually rides very smoothly at lower speeds, no need to pin it to smooth things out. It's firm, but compliant. Seems like a contradiction I know, but that's how it feels...

Yes, a stock rear without any modifications would not keep up, and be in danger of damage.
Why I refer to the rear as being such a liability for me currently, is that normally you can get a pretty good sense of when you're overdriving the truck through a certain type of terrain based upon the front end feedback. Now, the front just happily plows through everything, and you hardly even feel it. The rear on the other hand, gives you no warning, it just starts bouncing around. Not good to be having the rear bouncing you into 30 degree yaw angles at 140km/hr.

And this is with national +3 springs, RPG bumpstops, and icon 3" triple bypasses. It's just not on the same level, and it shows.
The lt kit can easily and comfortably slow down to run within the rear ends capability, but it feels so slow, as the front end is just gliding over stuff. Kind of funny really, because It felt like I was just flying at those speeds before.

A picture of the brenthel sprung under kit:



It has new shock mounts that must be welded on, uses as 12" stroke 3" king bypass, custom shackles and deavers.
Preserves the bed for cargo.
Jordan did mention a new driveshaft is necessary for full articulation, I emailed him back yesterday asking for details on that point, but haven't heard back yet.

My main point of contention right now is that I'm not sure a sprung under/ bed cage setup is going to be enough. I just don't know if I can get the performance (to keep up with the front) out of the rear with leaf springs.

you should be able to as long as you have enough wheel travel and the dampening rates right in the shocks

Part of the trouble is the up travel limitation by the axle hitting the frame.
Could notch the frame I guess...

Still limited by the bed, diff will blow through it. There's about 1.5-2" uptravel you can gain before serious mods needed. Either ditching the bed altogether or custom fab. I'm looking to have my bed floor & wheel wells raised a few inches and then notching the frame and doing a bed cage suspension. However, after being without my truck for 5 weeks and counting now, I am reconsidering how far I want to take the raptor and instead looking at buying a dedicated prerunner.

Exactly. Once you are notching and going with a full caged bed and glass, you might as well suck it up and link it. The financial investment is pretty over the top though.

Not too worried about the bed at this point, I'm primarily just hauling myself and a laptop at work. I plan on hacking it up to build a vertical dual tire carrier recessed into the bed where the stock spare is. Shamelessly copying the sdhq ecoraptor's setup.

So I've been out tuning on this brenthel kit.
It's ridiculous.
3.0's aren't even close. The lt kit sticks like a cat on Velcro.
You can crest a hill, or come out of a g-out, and immediately correct your line. Feels unnatural, the truck is way up in the air and you're totally in control. Same with big hits or g-outs, its very progressive and there is no big thump and subsequent upset to the chassis.
It sucks up the small to medium stuff with zero drama, its hard to tell you are hitting anything. Big stuff is more of a "whoooomp", not a "bang" like the stock shocks and 3.0's.
My wife lied to me, travel length certainly matters !

Something else I'm seeing on the gopro footage is that unlike some lt kits, it doesn't ride on the bumps in light to medium use. They only strike the lca on high articulation angles. Makes tuning easier as you don't have a big compression jump until very late in the travel.
I'm impressed as hell, can't quite believe how much faster it is now on my regular trails, yet more composed too. It is damn near boring on fast whooped out sections where I felt right on the razors edge with the 3.0's.

Worth the money and time ?
Hell yes !
I'm shocked how much better it actually is, I did not expect such a dramatic difference compared to the old 3.0/deaver setup.
Downsides, it does wander a bit more on the highway, it does feel a little like you're driving a trophy truck in terms of chassis response, and you've seen how they handle on pavement.
Upsides, it handles a little like a trophy truck in the dirt !

Glad you are happy with it. I have enjoyed following your build and looking forward to seeing what you do with the rear.
Since my truck was wrecked, I have spent a bunch of time in RSV1 and you are right, it's amazing the difference in how the long travel soaks everything up. Next weekend we are doing over 400 miles and we will be using a long travel sprung under and I am looking forward to seeing the difference to the linked rear. Has the same front setup, minus the 4.0's. You should come down and join us on a run, would be great to have you.
