Castor plates and 6" lift?

[T Y L E R]

Is this possible? Or do the plates have to come off ?

Not sure what my stock castor was, but after an OME 2.5 I had NO castor issues without modifying anything. So maybe my rig was one of the ones that came off the line with a castor around +4 degees.


I am quite happy with my 850J/863 & castor plate setup, just thinking out loud.

I have been wondering the same thing. I know i want to go to a 6 inch lift, but right now my caster is off with just the 2.5 inch lift, thus the need for the caster plates. THis is also the reason i haven't welded them yet.

So, both of you guys have a 2.5" lift and th ecaster plates with no vibes? That's amazing!

Alia176, I do not have a 2.5. That was a while ago. This winter I went with the equipment in my sig line. And without rear seats and any after market bumpers I am pretty light. Add to that clears all around, and I damn near float! ;p . I have no vibes and the truck tracks incredibly well.

Perhaps I've nearly answered my own question:

Get a castor reading at an alignment shop, and then see where 'this' particular rig sits in terms of upward potential. I understand that the 80's come off the line with a variance in castor. So will this variance still hold post castor plates ? Or do the plates lock the 80's into some static castor setting?

The caster plates just rotate the axle housing down at the pinion side which in turn adds more positive caster. So if you lift more, you will loose positive caster since the axle housing will rise at the pinion side.

So TY, are you thinking slee arms with the caster plates, or just caster plates with the 6 inch lift? Slee arms with the caster plates should be fun. if you ask me there is no such thing as too much caster

I guess bottom line is get an alignment, figure out the current caster and then go from there. There should be some old posts that state how much caster in degrees you loose per inch of lift. I think it was something like .5 degrees of caster per inch of lift?

Derek, you know me .. I have no idea what I'm talking about .. *L*


But I wassss thinking of my stock arms with the now welded in place Slee plates. And wondering how much further I could raise the truck before that equipment could no longer provide sufficient castor correction.

When you get to 6" lift you really need to move the axle forward as well. Caster plates do not do this.

Does this mean I would need longer arms with this lift ?

Riad, start by going to Mr Slees website .. click on it in his sig line. Then look for the 6" lift under suspension. It will detail what goes into the 6" lift.

T Y L E R,

I have read this (following) list many times in "Mr. SLee's" website. Therefore, I can see what goes into/with the lift. I don't see any (longer) front arms in the list, unless I am missing some thing. I assume, installing the lift will move the axle forward and one "may/does" not need longer arms. And, thus, my question was more directed towards that . So again I ask , hopefully with a clear tone, do I need to get longer arms up front to forward the axle or it happens due to the setup of the lift?

2 x SOF5FM Front Coil Springs

alia, i do have the 2.5 lift with caster plates and have a very slight grrrrrrrr in front driveshaft. It's not bad though.

Riad .. they are "1 x Slee Off-Road Front Control Arms" - 1 PAIR. They are BENT differently ...

From Slee's site :

Front Control Arms

The Slee Off-Road front control arms are made from 2", 3/8" wall 4130 Chromemoly tube. The bushing eyes are machined to accept standard Toyota oem bushings.

The arms are bent to correct the caster for a 5" to 6" lift on a 80 Series Land Cruiser. Additional correction can be achieved by using Old Man Emu caster correction bushings.

The arms are supplied as a ready to bolt in unit with new Toyota oem bushings installed. The bolt in arms are powder coated for maximum corrosion protection.

For those that wish to save some money, the arms are also supplied as bare units. You would be required to press the bushings out of the old control arms and install them into the new arms. We do supply 2 press tools that ease the removal and installation of the bushings.

So you DO need them with 6" lift. The description for the lift does not say that I guess. I have been wondering about the very same question with the castor setup and increasing wheel base with the 6" lift. That's good to know. Thanks

Riad, check this thread too about these issues.
