Spacer lifts:
Spacer lifts are designed to work with your factory suspension components. This type of lift is great for those looking to keep the stock XREAS. Spacer lifts provide added clearance for off road, but they provide no other benefits. If you spend a lot of time off road, or even occasional off road that’s at a moderate level, this probably isn’t the best option for you. Spacer lifts are not made to handle added weight, such as front/rear bumpers. Spacer lifts have very little effect on ride quality. All spacer lifts are essentially created equal. About the only difference between them is the material they’re made of, all end up with the ame results.

Lift amounts range from ˝” to 3”. With spacer lifts, it’s important to determine you want. Some people use these to simply get rid of the factory rake. This is accomplished by raising the front 1”-1.5” (most common, some have used different amounts). Others choose to lift both the front and rear. It is common for the kits to be sold in unequal sizes. The front is typically 1” higher than the rear, which also helps to get rid of the factory rake. It is important to note that you will gain double the spacer thickness in lift in the front ONLY. For example, a 1” thick spacer will provide 2” lift. A 1.5” rear spacer would net 1.5” lift.


This is very good, I was getting ready to do a search regarding tire sizes and lifts.

There are 2 additions to this that should be added by more knowledgable people.

There is a major difference in the types of spacer lifts- Top Load and Pre Load. The difference is in installation but also the amount of shock travel which impacts articulation.

The other item to add is the lift from using FJ shocks and coils. I dont know much about that but I see several people doing it.

Thanks again for taking the time to post this.

I really think the best installation guides are the ones you listed in your first FJ lift thread. I personally used those and didn't have any problems.

I believe 120 has some really good instruction threads for lift kit installs!

ARK_SWAMP_RIDER 11-20-2011 01:27 PM

I'll post a few of those threads up later, then add as stuff comes along.

Desert Fox,
IMO the preload vs topout spacer discussion is a thing of the past. most lifts now are 2" or under are topout. Those over use a combination. In the past, there were smaller spacers offered in a preload, buy I don't see that much anymore. If you think it'll be beneficial, I'll add that in. as for lift amounts with the fj setup, I have another thread with that info. There's a link to it in my original post in this thread. Its titled 4th gen: for all who've done the fj swap.

Let me know if there are any other questions or suggestions.

Amazing break-down of suspension options. Thank you

ARK_SWAMP_RIDER 11-22-2011 10:23 PM

Dividers have been added to hopefully make the long post easier to read. I also added links to several install write-ups that I've used/referenced. If there are any others you'd like to see included, or any info you would like added, let me know and I'll do what I can.

For instal instructions on front coilovers and rear shocks with pictures and torque specs, please feel free to use our link Overland Warehouse LLC Installation Instructions

We have had hundreds of people instal their own suspension following these instructions.

Regards
Mark

ARK_SWAMP_RIDER 11-23-2011 06:17 PM

Thanks for the info Mark, I've added that to the OP.

Overland Warehouse 11-24-2011 01:11 AM

Just as a notice of warning for many who instal lift kits on 4th and 5th Gens...

Please be aware that when lifting your rig in the back you can stretch the rear brake line if you are not careful.

Check by raising your truck off the ground and allowing full droop. Check your brake line where it changes from hard line to rubber line (look for it roughly the left side of the rear axle as it comes down from the body).

Now you also need to confirm that your are at full flex! Get someone to stand on the left tire to make sure.

At Overland Warehouse we include a brakeline extension bracket with our extended travel kits to alleviate this problem. You can also change to longer braided lines buit then, beyond the cost of the lines, you also have to drain and bleed the brake system.

Just a heads up. You dont want to be breaking a brake line while offroading!

Regards
Mark

Again, thanks for the info Mark. I've added that info to the original post.

Great info!

so i know i may be beating a dead horse here, but you listed the tire sizes to fit each lift. So any 275 in an 18 isn't going to fit? I currently have 265/60/18 Firestone Destinations, and want to put on 275/65 Duratracs... Will it take lifting both front and rear to manage this?

ARK_SWAMP_RIDER 12-05-2011 07:51 PM

The tire size is width/heigh/wheel. Some 275's will fit, all depends on the height. A 275/65/18, especially the Duratrac, will require a lift. You'll need to lift the front 2.5-3", so to keep the vehicle level you'll want to raise the rear as well (not sure if it's technically required for fitment, but is for aesthetics). Even with a 3/2 lift, so minor trimming might be required with those tires (mainly moving the fender liner forward).

That's in stock form. I see you have Spidertrax, they'll definitely rub. You'll need to plan on moving the fender liner forward, removing front mud flaps, and possibly trimming the front bumper slightly (even with a 3/2 lift).

momo.75 12-05-2011 07:57 PM

Just got my DS 2.5/1.5 in and was hopefully going to install it this coming weekend. As far as tires i am leaning towards the BFG Rugged Terrain A/T's in 265/70 18. I should be good with the fit, right? I already have Spidertrax on.

ARK_SWAMP_RIDER 12-05-2011 08:16 PM

The 265/70/18 measures 32.6" tall. You can use that as a reference in the original post. That's not a common size, so I can't say for sure. I don't think the body mount will be an issue, but I'd expect to do similar trimming as with the 285/70/17's. The only person I'm aware of running that size is yellowssm, but he's running 5100's and OME. He might be able to give you some feedback on the size and what's required.
