99 Highlander Coil Springs not good with Weight?

[eric_rosenwald]

I'm getting Billstein 4600s on the front and back of my 2000 T4R. It's 100% original suspension before this upgrade. I figure that it'd be a good idea to replace the stock rear springs, since I go 4-wheeling about once a month with a lot of weight. I figure it'll help out. I don't mind the extra 1" or so of lift from these:

48231-35210 yellow/red

From what I understand, these are the 99 Highlander "tall" springs.

I just want to swap out the rear coil springs when I get the shocks installed.

The thing is... someone in the forum said those springs don't handle weight very well. So what do you all recommend for rear springs, on a daily driver with occasional high-weight 4-wheeling, and brand new Billsteins?

I would say go with one of the ome springs over the 99s. i have the 99s and while i do not carry a lot of weight wheeling you lose that inch very quickly.

you can do some 4x4 FJ coils for a bit more spring rate. I'm running these

You can go for OME 906s
They say about 2 inches of lift but with the 4600's they sit really well with stock front coils. Handle weight well and provide a good ride.

OME 880/906 was my first setup and it was almost stock height. I would go with that over 99' talls because what it all boils down to is that you are still putting "stock" springs on that are no better offroad than your current springs.

I'll join the crowd and suggest finding an aftermarket spring. I ran the "tall springs" front and rear for a longggg time.

Stock truck would squat pretty bad with 3 passengers and the cargo area full of camping gear. Lost an inch out of the rear when I installed my rear bumper/tire carrier and corrected it with a 1.25" coil spacer for a while. They are realllly light duty springs.

Thanks. I'm new to the subject, and this really cleared things up for me. I can finally say that I'll make this purchase with full confidence that I'm doing the right thing!

In another thread, people recommended that I get a new set of nuts & bushings for the new shocks. I'm under the impression that when I order them (shock warehouse.com) I can buy a set of these. Is there a similar kit that I should get for the new coils?

If not, I'm going in to my mechanic with:

front/rear Billstein 4600s
bushing/nut set
OEM 906s

Thanks for the input! I'm going to go with your advice and get the 906s (the 880 refers to the front springs, right? I'm only doing the rear springs.)

As far as shocks... shockwarehouse.com is saying that I use all of the same hardware from the old shocks when i install the new Billsteins. But apparently they do come with some necessary hardware. I've also heard that I should get new bushings/nuts separately. Does this makes sense? Can I basically say, when I order on the phone, "get me a new bushing/nut kit to go with my new Billsteins, also" when I order the shocks?

Nope that should be good there is nothing needed to install the new coils. Good luck!
