OME BP51 Install

[Calokie]

So I got my bp51 install complete with arb UCA (wheel alignment is tomorrow)
Rides great at factory settings.
I’m set at level in the front and zero in the rear (I will be installing Dobinsons 0.5” springs soon to get some rake back)
So I have noticed a strange phenomenon since the lift was installed, I used to have a rough downshift clunk/learch when coming to a stop, since the leveling of the vehicle that learch/clunk has completely vanished and my stops are very smooth now. It always felt transmission / hybrid system related.

The KAON video LC appears to not have SDM. Without SDM it will unlikely be able to fully flex out the suspension. Tinkerer's Adventure have a video on this subject.



I'm currently all stock as well but have plans for small upgrades in the future, when I get to it I'll try to do it scientifically with measurements and things

I'm hoping we can get a mechanical disconnect in the future, although, iirc the difference is around 10% additional flex on this platform. It's nowhere near a solid axle, but I'll take all we can get.

More like 78%


Yes I know a lot of owners don't like this video lol

That seems like a huge number, from what I've seen the wheel travel difference isn't huge with the swaybar disconnected. It's not like a disconnect with a solid axle which is massive improvement. Iirc Ronny does a test in this video. There used to be a video floating around that actually went over the official differences.

OMG this modern suv doesn’t have the same feeling as my highly modified FJ with different tires etc…when I unnecessarily yank the steering wheel back and forth for no reason… it’s not supposed to do that

There’s definitely a materially noticeable difference in droop with sway bar disconnected, but I’d be shocked if it was a 78% increase.

549 to 631 = 15% increase

I remember that video. A lot of people have no idea how impressive that number is with the swaybar disconnect on an IFS, which IIRC is 300-series levels of flex. Even the 549 with the swaybar connected is fantastic articulation (for an IFS). They had a chart at the end which shown how it stacked up.

And........ how is the articulation compared to stock? No one ever wants to comment on this, and I had to press Jeff Westcott repeatedly before he finally succumbed and admitted that they "hadn't [actually] measured it" (re: the puck lift, which was claimed to have no effect, lol).

After spending 9 years in a 5th Gen and experiencing how much better the (stock) LC is offroad (it almost never lifts a wheel or slips), I believe that it is the articulation that allows it to climb like a goat. I'd like an inch lift for clearance reasons (any more and won't fit in garage), but I will wait for a solution that is confirmed to not decrease wheel travel.

Sorry for topping this old post and some of the older posts contained in the thread. I've been doing A LOT of research on these because I'm having them installed. The BP 51's do have increased drop. If you keep the lift at 2", you will have more drop than stock. If you go to max lift (3"+) you will not. You also will need to change the UCA's.

 

[BMFS33]

Regarding the collar lift, it is almost guaranteed to have less overall wheel travel than stock by limiting uptravel without any additional downtravel. It's just simple physics.

Regarding suspension kits that will give you more downtravel, you'll also need to factor in replacing the CV axles with those from a TRD Offroad or Trailhunter Tacoma, as the CV axles are what limits the downtravel on a 250. I suppose a diff drop can get you there, too.

The LC stock CV Axles will not limit the down travel unless you are trying to substantially increase articulation. Then CV's need to be replaced on almost every OEM suspension set up. What you must do is change the UCA's to get a little more drop when using the BP-51's at less than max 3" lift.

 

[BMFS33]

I’ve read in several places that ARB/OME says the angles are ok even at 3” lift. Once I get mine on, I’m going to check for myself just to feel more confident.

General rule of thumb that I've been researching is anything pushing over 2 - 2.5 you should consider a diff drop

 

[BMFS33]

Hows that diff drop install? Im interested in seeing you CV angles. I have my new BP51s setting in my shed and my LC has been at the collision center going on 3 weeks. I'll be doing a 2-2.5 inch in the front with a diffdrop. Yea they say the CV angle is fine up to 3 inches but why wouldn't you want a diff drop to level out the CV angle and hopefully lowering the chances of popping a CV.

My understanding, and I'm no suspension expert, but I did stay at a Holiday Inn last night, is that 2 to 2.5 is within tolerance for the CV's. I've confirmed with Mountain Yotas and Slee Offroad in Colorado.

 

[BMFS33]

Save your $ for diff dropped if you just do light-medium off-roading or just MC

The $ spent on diff dropped is not waste if you do medium-heavy off-roading.

Don’t just say “waste” or “must do”. Keep it ourself / yourself. A lot of people just arguing and judging all kind of things with thousands of endless words but no illustrations/ photos (media)

Attached are before and after diff dropped which I posted a while ago in diff dropped / lifted thread . Hope it helps someone to make decisions

Happy Holidays and LC to All

That looks pretty significant, especially when getting max articulation. How much more down travel does your new set up have over OEM?

I feel like the way it was designed by Toyota is within spec
2-2.5” is proving to be significant with the Tripod CV axles

I know very little about this, which is why I've been reading all of these old threads and articles and YouTube and other sources of information, which all begin to take sides. Let me also be clear that neither MountainYota nor Slee said they were "within tolerance" they did say that they run them and set them up and have seen no issues to date. Personally, I'm landing at 1.75 - 2 in the front for me. That's as far as I feel comfortable going regardless of what I read.

Did you have any trouble using those OEM 18s after installing the BP51s and UCAs? I have a set of 275/70/18s on my OEM 18s that I’d like to reuse but I’ve heard that they won’t work with the BP51 and OME UCAs.

I’ve had no problems reusing the original rims

I have BP-51s, OME UCAs, and the OEM LC 18” wheels.
They clear everything in most conditions but the front tire is pretty close to the knuckle upright and the tires can rub the rear reservoir hoses at full articulation.
It’s worse on the passenger side because of the track bar angle, so track bar correction would help some (or maybe just make it rub equally on both sides).
I went with 30mm RokBlokz spacers to fix that, and for the other benefits of being a bit wider.
BTW, those spacers are on sale right now. If I had waited one month…

Edit: also running 275/70/18
