Long Travel AHC

[AnyMal]

1.Increase ride height at neutral position 2.increase droop travel
3. adjust ahc pressure to normal or acceptable range.

1. Move all sensors down up front, up at the rear. Play with them until its sitting right.

a) alignment​

b) mess with techstream if you are "OCD".​

2. Spacers on top hat of front shocks, shock mount brackets in the rear. (you can always have things fabricated for you too)

a) extend brake lines​

b) alignment​

​

3. Fiddle with springs / preload. For anything sensor only in factory range of "adjustment" the westcott kit is pretty good

a) alignment​

Thank you ! I already did one 10mm spacer and max sensor in the front but will be adding another spacer and modifying the sensor link or adjusting tech stream. I will also be adding a spacer to Timbren bump so the shock won't be the stop. If I add more weight with bumper and winch I will add pre load collar to increase spring rate and reduce ahc pressure.

Just reading about your plans, how much of a ride height are you trying to get? Do you ever intend to go into high mode after doing the static lift?

About double the standard sensor lift. I think max sensor lift is about 1.5" so it would be about 3". I will still use high mode in 4 low and this shouldn't be a problem as the entire shock/strut is moving down and ahc is only being adjusted to maintain the new ride height. Essentially the shock shaft should be close to its original position once sensor is adjusted. The only concern was angle on axle and cv's but doesn't sound like it a problem or require a diff drop.

With a 3" static lift, I'd be concerned about sway bar end link bind and UCA bind as the system tries to go into high.

I need to investigate further on drive line/cv angle. Sounds like some have already done it and may have removed sway bar or extended links. No mention of other issues and said it's close to LC angles. I am still unsure !

Yeah, at 3” stock UCA clearance is definitely a question mark. Didn’t keep mine on long enough to know its limits.

@Expoguy

After the 10mm+, yes, don’t forget to augment bumps. Thanks for remind me of that one. Need to order them before I pull the suspension apart for the millionth time.

Well I’m new at this and not as creative with the solutions yet!

But I did the max AHC sensor lift without tech stream adjustment and next up is the Westcott spacer and preload kit with a passenger side rear spring on the driver side (USA).

Nice!

Are you sure that spring is oem? It looks too skinny from my memory.

Also remind me if you are using factory top strut mount studs, the forum would benefit from knowing if that westcott spacer bolts up with proper thread engagement. Im not sure who else has done it that way. It should, its just going to be very close.

Yep, rear passenger coil bought directly from the parts department at a local Lexus dealer and we double and triple checked the part number.

I will be using the stock studs already installed, basically I didn't want to try to source alternate longer studs (based on earlier discussion that the right stud was hard to source). So I HOPE it all fits! I made this choice based on others (also don't remember who, I thought you did) already doing the Westcott so

You should be good, and not much worry on over-torquing those studs to stretch them a bit as they are not under shear.
I would also get a 10mm OEM spacer ordered just in case if you want to not have to delay things once disassembled.
Be VERY careful with shock coil compression. Dont have your head or body near it, dont put your hands anywhere near the coil or inside the gaps.
Or just have a shop do that part for you for the bottom spring seat. They have hydraulic press and cages for this exact thing.
Oh and get a socket tool for your bump stops. They are a PAIN to remove.

@MTKID You did yours with factory top studs & the westcott 12.5mm top puck right?

Anyways good luck and DM / post here for help. No better way to spend a few hundred bucks on a lifted LX.

I just got Wescott parts that will be installed next week. I currently have LC spacer, max sensor adjustment and added another 1" to sensor arm yesterday. The plan is to to stack the Wescott spacer and LC spacer with the extended studs. Hopefully this all works out as the ride height is where I want it. It currently rides a bit stiff but once we install the second spacer it should bring pressure of AHC down.

Added another 1" to sensor arm and ride height/lift if about right for the two spacers being stacked. I will know next week when we do installation.

Which studs did you source? Id like to replace mine eventually when I refresh everything. Right now, im not taking the shocks apart again...
But probably in a year or two when i do globes. Haven't decided yet. Might do em soon at 80K.

is it just me or is the front setting high? And are you sure the stiffness isn't due to running out of down travel up front?

The ones listed in original thread that are sxs wheel studs.

Im sorry but search is failing me, can you post a link?

Yes, I did use the factory studs with the Westcott spacers, but I don’t think many others would be satisfied with loosing a thread or two of engagement. We did use the locktight, but still seems like a longer stud would be best…

Hmmmm that might be a bit less than I was expecting. I kind of thought it would be roughly flush.
