Cure for the Common Sagging Rear End?

[Kentonius]

Hey everyone - looking for some guidance here. My rear end sags! Currently, this is affecting only my 2002 LC. I'm on stock suspension.

On a recent trip to Durango, I tried out some airbags - these were great when fully loaded with 3 kids, the wife, and a TON of gear! However, I might have left them inflated when attempting some rough trails, and some way through heard "Pssssshhhhhhh"... Ok, time to replace a bag.

Are there other options that can help prevent the dreaded sag? I'm not looking to diff drop, but moderate lift is ok. It's a daily driver, but will most of the time have the family inside - about 600 lbs of us. Other than that, loaded with gear for family trips. Currently, no trailering, only bikes on the hitch.

Thanks!

OME 2865 Springs are probably what you're after, although you could just replace with Toyota OEM. The OME 2865s are a good update for what you describe, and will give you a slight lift. I've been running them since I bought the truck. They aren't rough and are good with a full load of camping gear. I'm upgrading to 2863s now because I'm adding a steel bumper.

I got the dobinson c59-223V springs installed a few weeks ago. They lifted it about an inch maybe 1.5 inches. I’m going on a 7000 mile road trip in two weeks with 3 passengers and lots of gear. I’ll post how it goes.

If your springs are relatively new, you could get the iron man spacers and install them. But in order to do that, you might as well spend the money on new springs since you have to remove the current ones to install spacers.

Currently sitting on 21 year old springs... the airbags were a quick and cost-effective way to maintain ride height, but I'm not a fan of the handling with airbags...

Springs sag over time. I would start there.

True... but I've heard just replacing with stock may not be the best option over time. I'm all for aftermarket at this point, just looking for any suggestions!

Was just talking about this today with another Mud member.

In for more info/opinions.

OME has a variety of springs available. This chart breaks down the differences.

I opted for the 866 coils. They provide around 30-40mm of lift (stock torsion bars can be indexed to match the lift) and are dual rate so they get firmer as more weight is put on the rear. The rear of my 100 used to sag like crazy when loaded up for a trip. Now the sag is minimal, even with a trailer attached. I'd be happy to let you check out the 866 coils in my 100 since you are relatively local.

It would be really cool if there was like a variable device or system, kinda like that airbag, that could inflate and deflate to keep the height constant even when the load varies. Except not an airbag because those aren't all that reliable. Maybe something hydraulic since that can be really robust and the pumps last basically forever.

You could have it on each corner too, or at least split 3 ways to keep it all level. And then you could use it to create an on-demand lift or on-demand lowering for garages and old people.

Toyota/Lexus should work on something like that...

When I went to replace my sagging springs with OEM, the dealer I ordered from said they're back ordered, or one of them was.. and since I wasn't in a rush to get them I waited. But after 2-3 months I gave up and went for Ome 865s, installed with a 10mm spacer on the driver's side (gas tank side) to match the originals. Together with them I got airlift bags for the days I'm over loaded. Also, OEM springs are double the price.

If I'd have to do it again, probably I'd wait or search harder for the original springs. I don't think the springs match the stock shock properly. They're fairly new shocks, and for some reason, it feels like the rebound is off. But not too bad, still more usable than saggy 20yo springs..

I've got a name already picked out...

I am curious how the dobinson c59-223V compares to the OME 866....

More seriously, I had Dobinsons 200kg rear springs in my previous LC100 (due to rear drawers and a trailer), and even unladen the ride wasn't too bad. Because it lifted the rear, I needed a different shock absorber - so if you go for non-standard height springs, invest in matching shocks as well.

Many people here in Oz rate Dobinsons over OME. Dobinsons make their own springs.

Any feedback on these springs? Thinking of purchasing and installing on my rig. Any feedback would be really appreciated!
