OME stock height replacement or 2.5" lift

[Twinair]

I debated this as well. I settled with OME stock height with 33's. When I'm due for tires I would like to add 1" spacers all around and go 35". I think if you decide on 2.5" you will wish you had gone 4". If 4", wishing for 6". I'm staying with what allows clearance into my garage opening without removing my load bars.

For those Land Cruiser owners who are new to this, it's not as simple as just changing springs when you go to a 4, or 6 inch lift. Along with the cost of new springs you'd better plan on having extra money available to spend on DC drive shafts due to different drive shaft angles after you've completed the lift.

Plus longer brake lines to each caliper, along with a caster plate setup up of some kind so you don't get the dreaded death wobble if you plan on driving your Land Cruiser faster then 50 MPH.

Oh, i almost forgot one more thing you'll need to deal with, and that is adjusting, or removing all together your rear brake load sensing proportioning valve.

The issues i listed above are the main reason why i decided to go with the simpler, and MUCH less expensive stock height OME spring setup.

All great and valid points. I will say that even after deciding on the stock height springs my truck required castor correction. I spent a year playing with different degrees of toe in, adjusting the play in the steering gear box, and a couple of trips to the alignment shop where the printout showed negative castor. "That can't be! I'm at stock height!". I finally installed castor correction plates last weekend and I'm pretty irritated I didn't do this a long time ago. Now my thought is, now that I have castor correction I should go a little higher with my lift. But you're right @Rifleman. The higher the lift, the more modifications required to make the truck right. Every truck is unique and may require adjustments and extras others didn't need.

I went OME stock height which gives you about 0.75” or so of lift with no issues. I went to 285 BFGs (33”) at the same time. Has driven perfect for the last 7 years or so.

SNIP...Every truck is unique and may require adjustments and extras others didn't need.

This is rather unusual, as most stock height installs don't lead to the need for further compensatory adjustments. Still, it's worth keeping in mind as a possiblity.

it should be easy for me to find 33s because my truck has the old school stock 15 inch rims. how does the ride compare to the stock suspension?

 

[WarDamnEagle]

Better. But I’m not that picky.

haha that seals the deal. thanks Ill post pics when I get around to installing one. I gotta scrounge some cash too.

Here’s mine. Not a great pic but gives you the idea.

Ride is great on smooth roads but a bit more harsh than stock over rough pavement. Then again, I run 60 psi tire pressure on the road. Why? Its good for a 1/2mpg improvement. That's nearly 4% fuel efficiency gains! Offroad after airing down is where the suspension upgrade shines.

 

[Rifleman]

Twinair you may be running way to much air pressure for the street, below is a link to a thread that has a section by LandCruiserPhil that outlines a simple way for you to check to see if the 60 PSI your running is to high, or just right.

Tire pressure question?

Here is a link to a Mud member who lists what his before and after ride heights were when he change over to stock height OME springs.

Here is a link to the adjustment that are needed on the LSPV when you install the OME 2.5 inch lift.

LSPV with 2.5" OME

I've searched and read. Do I need to move the bracket? Or do I just need to udjust the nuts? Hayes

And here's another thread on adjusting the LSPV.

LSPV Adjustment with Pictures

Ok. Read a lot of posts. Looks like its .25" per 2.5" lift, so .1" adjustment per 1" lift. So for a 6" lift that would be .6" of adjustment for a starting point? Then test and adjust? Any legitimacy to this equation? I realize the proper way, but in advance of redoing the entire...

Older thread, I know. But stuck in the middle here. For those of you that have put spacers, where'd you get them?

 

[Corbet]

I used the Man-A-Fre spacers with 2” coils before going to 4” coils.
