Revtek - Sagging Rear

Recently intalled Revtek spacers (front and rear) on my 97 SR5 and my rear sits 2" lower than the front. I upgraded the struts and shocks to Rancho at the same time but am still running the stock coils. Truck has 172k on her so clearly I'm experiencing the 'sagging rear' I keep reading about.

So, how do I get her level? I'd like to stay with the spacers, at least in the front. Here are my thoughts:

1) Performance Products 1" lift springs in the rear with the current spacers (assuming I'll get more than 1" due to the 172k mi sag) or,
2) OME 891s and no spacer and can I/do I leave the spacer with the OMEs?
 
I had the same issue with my '02 and it only had 60K at the time. 3rd gen rear coils are pretty weak and will sag over time with the added stress of the spacer. I wouldn't run the PP or OME springs with a spacer. I'm assuming you did the 3" Revtek spacer lift.

The PP springs won't give you enough lift by themselves. IIRC, the OME's you mentioned are 2.5", which would work, but the front would still be higher. You might want to look into Land Cruiser coils for the rear. You'll want the FRONT springs off of a 93-97 LC for the REAR of your rig. They'll give you about 4" of lift in the rear, but will sag to about 3.5", which is about perfect. You'll get a slight rake with the LC coils. This is the lift I did, so hit me up if you have any questions.
 
LC coils? I haven't heard of swapping with them before. What's the difference between those and Tundra coils. (have been hearing about this swap)
 
Initially, I did a search of local salvage yards for a used set. Used coils are nice because they've already sagged out. Used sets were running around $80 for the pair through the local salvage yard, which I thought was pretty high.

In the end, I ordered a new set from Toyota Parts Sales: http://www.trademotion.com/partlocator/index.cfm?siteid=214074. These guys are great to work with and the parts always ship fast!

IIRC, they ran about $120 new. They gave me 4+ inches of lift in the beginning, but now have sagged to about 3.5, which is perfect for me. Let me know if you have any other questions.

Tundra coils are used for front end lifts and Land Cruiser coils are used for the rear of our 3rd gens. Interestingly, we need FRONT coils from 93-97 LC's for the REAR of our 4Runners. 2nd generation Runners use REAR coils from the Land Cruisers.
 
Response to your earlier question - yes it was the Revtek 3" but I'm pretty sure I only got about 2" in the front. I can say for sure that I'm 2" lower in the back now. Front: 38 1/4 ground to fender lip; Back: 36 1/4. Sounds like 3.5 would be perfect. How long did it take for the new coils to settle?

Mine settled after a few months of driving. They'll settle faster if you tow or haul a load or do anything to put stress on them. I've posted a link to my profile on Yota Tech. It shows the transformation of my rig and what the LC coils look like on the rear. There's a little rake, but it looks great to me.

You said that you can use Tundra coils up front. Do you use the fronts off of a tundra or the rear and how much lift do these coils give?

IIRC, you use front Tundra coils for the front of our Runners. A lot of guys use the Tundra springs with longer bolts and top out spacers to give them ~3" of lift up front. Definitely do the diff drop with that much lift.
 
So I have a Revtek lift, could I another couple of inches using the Tundra coils up front, and the Landcrusier coils in the rear.

That's a good question. From what I've read, the max lift you want to do in the front with IFS, is ~3". The suspension just won't handle any more lift than that. The Tundra coils with topout spacers will give you close to a true 3" lift or so. Be sure to invest in a diff drop kit from Sonoran Steel. That way, your CV angles will be correct with that much lift. After settling, the LC coils will give you about 3.5 inches in the rear. That's about the maximum suspension lift you can do on 3rd gens. If you still want more, check out Roger Brown body lifts. I wouldn't go more than 2" max though. Good luck!

Forgive me for not knowing this but, what do you mean by a little rake?

Rake means that the rear sits a little higher than the front. If you check out my profile in one of my posts above, you'll see that mine has some rake to it. I like the slightly raked look.
 
The OME 891's will give you 1/2" of rake, which works best. I went this route as well since my Revtek rear spacers sat about 2" shorter than the front.
