Rear Control Arm Parts Numbers

[xychromosome]

My first set of Ironman front springs were from 2021. By early 2022 they were sagged out and contacting the shock body. Ironman sent me new assembled front struts under a warranty claim. Those then lasted 3 more years and now are shot. So as of today I've gone through 2 sets of Ironman front springs and 1 set of Ironman rear springs....on a rig with stock bumpers, no winch, etc, that just sees towing a 4K trailer with either a WDH and airbags.

But, the shocks themselves are still great - front and rear - it's the springs that suck(ed). We'll see how the new front springs do...hopefully better as they are definitely thicker.

Interesting......
I have the same front and rear springs, also from 2021 and haven't noticed any sag so far, after ~60k miles. I added some extra weight to the front end earlier this year (front bumper and winch, 130lbs) and was surprised that the front end didn't drop any, and also doesn't dive when braking.

They might just have crappy quality control. Like buying something from Harbor Freight tools. Sometimes you get a great one, other times they are bricked within a month . The cost of low prices.

Ah. That makes sense. I just checked and mine are actually the 2" +600lb springs so hopefully they hold up a bit better. Good to know on the Dobinsons. Let me know how they tow if you get a chance. Thx!

I finally actually checked my tongue weight today. It was way higher than I thought it was, and too high for a GX without a WDH. This shouldn't have trashed my springs (the bags should have been able to take up all of the slack). But, I am still amazed and how well the rig itself handled this weight - including on curvy mountain roads. Shows that Toyota has sandbagged the tow ratings a bit.

I'd still suggest checking yours if your back end feels a bit saggy. If you don't have a tractor sitting around, you should be able to check it at a truck stop scale, by going through with the trailer hooked and unlooked and recording the different weights at each axle.

Looks like Freedom Offroad has adjustable upper and lowers, full set for $490. That's way cheaper than OEM, thicker with pinion adjustment and they now use hardened rubber rather than squeaky poly.

While I don't have experience with Freedom, they are 100% a lower-cost parts company. I'm betting those are Made in China. Also, with being adjustable, you'll then have to adjust them perfectly so the rig isn't dog-tracking. They appear to be just threaded on one end, so adjustment will require removing the arm from the bracket, twisting it 180 degrees, then re-installing it.. From having done this on my rig recently, it's honestly a major pain and a 2 person job for the upper links (lowers aren't too bad). With 4 arms I see that being a major PITA, and it might not be possible to get it perfect without an alignment machine.
