4th Gen Suspension Options/FAQ

[ARK_SWAMP_RIDER]

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.

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

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]

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).

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]

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.

Yeah, i just used the calculator and realized that a 265/65 18 has the same 31.6in dimater as a 265/70 17. Here is how it would break down.

Tire Specs - 265/70 18
Sidewall - 7.3in
Radius - 16.3in
Diameter - 32.6in
Circumference - 102.4in

Tire Specs - 265/65 18
Sidewall - 6.8in
Radius - 15.8in
Diameter - 31.6in
Circumference - 99.2in

Tire Specs - 265/70 17
Sidewall - 7.3in
Radius - 15.8in
Diameter - 31.6in
Circumference - 99.3in

I will probably go with the 265/65 since i have the 18's

 

[ARK_SWAMP_RIDER]

Even with the 265/65/18 you'll still likely need a little work to make them fit. I'm running 255/75/17 with Spidertrax, even with 3" front, 1.75" rear lift I still had to move the liner forward and take the mud flaps off. It's a slightly larger tire, but I've also got more lift. Even with the liner moved forward, I still get a slight rub at times.
Tire Specs - 255/75 17
Sidewall - 7.52 in
Radius - 16.02 in
Diameter - 32.05 in
Circumference - 100.6 in

Would you guys mind me asking how bad the rub would be with this setup?
Full FJ TT
DS 2.5/1.5
All-Pro 1.5" spacers
Duratrac 265/70/17
And also a V6 if that changes much

 

[ARK_SWAMP_RIDER]

Move the liner forward and possibly trim the edge of the bumper. Read this page, almost identical to what you're looking at.
Toyota 4Runner Wheel Spacers

 

[kkz]

Ah yea, I've read that already. I was hoping I would have less of a problem with rub with the extra lift from the FJ setup, since JA only runs the Daystar kit from the last I time I checked. Would a body lift help at all with this issue? I didn't see this answered in your OP, sorry if you've covered this already.

 

[ARK_SWAMP_RIDER]

You're right on his setup. His tires are also a lot less aggressive, the duratrac will be harder to fit. A body lift would help, but IMO that'd be too much lift for a 32" tire. It shouldn't be too hard to get those to fit, but woo require some modification.

I have 265/65/18 on my 4runner with 18X9 +25 wheels. This has the same effective offset as stock wheels with spidertrax. I have Bilstein 5100s set to 1.75 in front and stock rear. This gave me a 1.25 inch lift in front. I get no rubbing at all. I have done no cutting or trimming and I still have all the mudflaps on.

Thanks for all the help ARK. Maybe I'll just put the two front spacers on first to see just how much it'll clip my bumper.

 

[ARK_SWAMP_RIDER]

No problem, glad to help. If you haven't noticed, I like to plan for the worst, that way you're prepared. You may not have that much trouble, and if you don't that's good news for you

So you have bilsteins up all the way and fit 265/65 duratracs?? So could i fit 275/6 duratracs with minor rub if i were to do bilsteins???
