[macscac]

Dobinson rear springs arrived today.
Looking forward to getting these on and seeing what changes!

Springs installed!
Haven’t driven it yet so not sure how every day commute will be yet and I won’t be able to hook it to the trailer till next week but we are getting there!

Used the 10mm spacer for the kdss so I wouldn’t lean and it’s perfect

Well they definitely helped balance it out with the front spacers, so it looks much better now!!

For those who ask again, it's C59-505 with PS59-4023 spacer

I would really suggest that your money would be better spent on a good, properly adjusted wd hitch. That way, you’ll preserve the feel of the stock suspension when not towing, which I expect is your normal situation.

Here’s a pic of my setup. Trailer weighs about 4K pounds all loaded. Very stable on the road, balanced and no airbags, non stock springs, etc. If you want to make a more important mod, I’d add a transmission oil cooler.

It's not the suspension - get a WDH and airbags and you'll eliminate the droop immediately. Also it is a LOT safer for you and everyone else on the road - no sway issues - I tow a 23' TT 5000km a year with a hitch weight of around 500lbs and TT weight of 4000 lbs - no droop and no sway - I set the airbags to 25 psi, crank up the WDH and good to go. Then once the TT is at the site, the suspension (I have 5100's all round) is good to go for the trails, beaches etc and is not so firm it shakes everything around.

appreciate the response!
the wd setup wont eliminate my reverse rake due to the level kit in the front of my car so thats why i went with hd larger springs in the rear to offset that tongue weight

i have towed the trailer several times now and have zero sway or bobble..
this thread is really just about eliminating the sag that i have brought upon myself

 

[macscac]

and....

in full disclosure..
most of my sag dissapeared as soon as i removed those stupid 'TRD OFFROAD' emblems and the overland bound badge from my c pillar

don't fool yourself with thinking the sway isn't an issue - think about a semi truck with a 53ft trailer passing you going 80 mph on the highway.........

Firestone Air spring helpers 1000lbs rating.

i just installed these took 2 hours. $100.00 on Amazon.
what a difference, just got back today from a 1000 mile trip made it solid as a rock highly impressed. i also suggest a re curve 3 weight distribution hitch it is the bomb.

I wonder if air bags would solve your problem!

Hooked up the trailer and ran it home to get ready for an outing tomorrow.
I am very pleased with the new springs.
They are just the ticket.
Thanks dobinson’s!!

I'm dealing with the same problem right now. We purchased a trailer and I'm going through all the necessaries before we start towing. How does your 4 runner ride unloaded on the daily?

Ever since I saw these photos, I've been in a "maybe I should get a trailer" wormhole on Youtube. hahaha

the back end is a bit stiff while driving over speed bumps in parking lots and washboarded service roads but it its not a huge deal to me and still drives fantastic when i drop my tire pressure to 16ish lbs while wheeling

in full disclosure, i had gotten some dobinsons UCA's and front springs to bring the front up 3" and i ditched the spacer kit.
since installing that with the front, i am dead level unloaded but have a smidge of rear sag again so....

i have just ordered an inch taller rear spring that should be arriving in a couple days and because i was going to have the rear springs out, i decided (what the hell) and ordered the firestone helper bag kit and will be installing that as well

do it Mike!
it has been 10 years since our last trailer and i forgot how nice it is to just take your home on the road with you!

Thanks for the info guys! I'll be ordering a lift from Dobinsons Mike in the very near future. Looking at the 2.5" springs in the front and either 1.5" normal springs + airbags, or 1.5" 200lb springs for the rear like you did. Our TRD off-road has KDSS. Trouble is I really like the smooth ride and how the stock suspension handles washboards, but I need support to tow the camper trailer.

We plan on towing for a few months starting next summer, around the US. We'll take a ton of trips off-road to trailheads, campsites in the woods, etc. without the trailer hitched up during our trip.
