Desperate for airbags or something to eliminate rear sag

My 2.5 gen

 

Obviously you've been getting good advice so far but my biggest suspicion is the fact that you have a sport. I am sure there are tons of people that will bash me or have something to say but that has always been a thing for me. A "sport" suspension is not going to be designed nor tuned for towing or offroading yet tons of Toyota owners don't see it the same way I do...

 

I was thinking the same thing. Hooking up a trailer to my ‘22 with Load Leveling air suspension is awesome. Watching it level out as soon as weight is on the hitch is pretty cool. Definitely was built for towing. Hopefully OP can get some aftermarket air bags soon. They really are awesome for towing.

 

I think you guys are on to something with the sport because it seems to have a heck of a lot of travel in there and it’ll still squat more at that . I need the air bags or somebody to tell me what land cruiser suspension mod to order and where and I’ll be on it

 

My trailer tongue is 500lbs and takes my truck down past level from a 2 inch rake. Tundra springs are jelly doesn’t matter the gen. There is an inside coil airbag kit that you can jam in there

 

I hear you but squatting with stock suspension is nothing new to any trim level. All 2nd gens were the same way. Toyota tunes the rear suspension toward comfort, not work.

WDH and air bags or timbrens or RAS or new springs (leaf or coil). Many people beef it up and have no issues. How far they should go beyond what Toyota says they should is a source of endless debate here.

I will say that I used to load my 4Runner down for trips, and when I put airbags in its rear coils, I could lower the psi down to 5 and not notice they were there.

 

WDH and/or a trailer that's an appropriate size for a halfton to tow.

 

Looks like the sport suspension theory is defintley accurate

I thought the 3rd Gen SR5 Sports were lowered in the front, giving them more rake.

 

Check these options out OP

Doesn't appear so based on that article.

Edit- I guess it could be if an sr5 sport is under the "sport suspension" umbrella

 

Also appears dobinsons has some rear options but you'll end up with lift

I have dobinsons full kit on my 2.5 gen , I love it. Also if you go dobinsons hit up 1stgenoffroad.com they sell dobinsons and everything they carry is free shipping. You may have to call them about ordering 3rd gen stuff not sure they have that are their website.

 

If your trailer is really 7000 lbs then your tongue weight is probably more like 925 lbs. I dont think you have enough hitch.

Im running equalizer 1000 lb bars on my 5500 lb trailer, because equalizers next size down is for a 600 lb tongue. I know my tongue has more weight on it than 600. they level out my coil sprung lexus GX nicely

 

I might know what the problem is. Tundras have flexible frame, so if they add beefier suspension, people will load them more because it won't look squatty and will end up bumping their beds against the cab like was posted somewhere in a other thread with dude pulling camper out of the sand.

This is like a safety feature, you see truck squat and you know you've reached the limit of the frame. That's how I judge how much weight is in the bed. An inch or less to the bump stops: fully loaded.

 

Check out the 3rd Gen Suspension Lift - MEGA THREAD we've put together. Even though you don't want a lift, you're still dealing with the same solution...heavier rear springs. There's links to the 2 different Dobinsons HD springs available for the 3rd Gen Tundra. There are 2.5" lift and a 2.0" lift versions of the springs.

That being said, you'll get quite the rake when not towing but it should even you out under major load. In my opinion, you're best course is it go bags so you can control the suspension differently for towing vs non-towing. My 2 cents.

 

So I just need to replace springs or will I need other parts aswell ?

 

I always have a load so it make work well

 

If you're going increase the rear travel by 2", which is what you'll be doing when you're not towing a load, then you will want the following:

• Rear Springs
• Extended Brake Lines
• Extended Rear Shocks
• Adjustable Rear Track Bar (Most likely - to re-center the rear axle)

You're probably ~$1,300 in parts plus install labor.

But, again, you'll increase the rake 2" in the rear when you're not towing. It'll look a bit like a mild "hot rod." haha

 

Also to get that down with dobinsons spring you would need a pretty substantial constant load . It takes quite a bit to bring them down

 

Yeah. I've heard they're a beast. Everyone I know that have used Dobinsons springs are using them on expedition/overland rigs. They're throwing a lot (and I mean a lot) of weight in the rear. I'm talking Alu-Cabs, water tanks, or rear bumper mounted 35" spares, etc.

If his tongue weight is well north of 500 lbs...especially if it's close to 900 lbs as someone mentioned...he should be able to take a lot of the rake out of them under load. But when not under a load...totally different story.

That being said...I'm offering advice as someone who has 100x more experience lifting vehicles than towing with them. All of the towing guys are probably saying, "Just put air bags in."

 

try roadmaster active suspension, wait.... they don't have leafs anymore NVM

 

Every Toyota truck I have owned has needed additional support at the rear leaf springs. I would go to a 4x4 shop and have them add a leaf at the rear on each side. I see many Toyota trucks and 4Runners with the rear sagging and no load at all. At this time the best option is a set of SuperSprings added to the rear. They only come into play when the load is too great for the factory springs.

I added a set to my 2500 truck and increased it payload capacity from 2800 lb to 4000 lb and could put a 3700 lb slide in camper in the bed with no sag at all. The SuperSprings take less than an hour to install and can be done with the truck's wheels on the ground. Nothing to adjust and nothing to fail. If only one air bag fails on a trip it would be a real problem.

Adding to the load support is also good for the life of the shocks which otherwise are working overtime.

 

Or just get the correct wdh spring bars.

 

Can he add leaf springs to a coil sprung truck?? He's in a 3rd gen.

 

Don't waste your time with that troll and his terrible "advice".

 

OP, think twice if you want new springs. Unless you’re planning on a lift or something, why ruin your unloaded ride? You want help with towing, why add rougher springs every other day of the week

 

As previously mentioned you should probably have 1000# WDH bars. Once the trailer is loaded up with your camping gear most of which will probably be biased toward the tongue, they will be spot on. My blue ox swaypro WDH with 1000# bars are perfect for my 32’ trailer which is about 6200 lbs dry.

 

Good looking truck.

 

If you're looking to add a little extra beef to the rear of your truck, we're happy to help. I've lifted my tundra 3" overall and am happy with the ride quality. If you're looking to do towing I might suggest heavier springs in the rear but otherwise, I've just created a kit for Tundra owners who want to lift the rear 3".

Here's how the rear end will sit. Keep in mind I have a few overland decorations on my rear end so you might yield a bit higher lift on yours.
