How did you calculate your mpg? Your odometer is now is now off by 7%
Of course it is very subjective from driver to driver. Suspension is very personalized for each of us.
So instead of losing 2 mpg, I've lost 1.86 mpg?
I agree with most here, keep your lift modest and/or do the groundwork to correct its geometry. Even then it’s not going to ride like stock. For most that’s ok, it’s a trade off, capabilities offroad for on road manners.
Personally…. I think the first modification one should make for better off-roading in the GX is a cheap daily driver lol. But that’s another conversation.

No. You put on larger tires meaning the odometer is now under counting miles by 7%. This also means if you used the trucks computer for your mpg, that is also off by 7%. Your 15 mpg average is more like 16 mpg.

Use your phone's GPS and see what your speedometer reads vs. your phones GPS. I suggest using as high a speed as is safe or legal. Perhaps get your speed to 60 or 70 mph, then see what your GPS is. Again a higher speed will give more accurate readings.
With the size of my tires, my speedo is about 10% off, so if it reads 70 mph, my actual speed is 77 mph, if it says 50 mph, my real speed is 55, etc.
And just for everyone's info, regearing your diff's will not adjust the speedometer.

Yep, well... almost 35's, they're (BFG M/T) 315/70R17's which equates out to 34.4" which is larger than my last tires: (BFG A/T) 285/75R17's.
Unfortunately there is nothing out there that for sure will correct our speedo's. But 10% is an easy calc to do in my head when driving.
265/55-R19 vs 315/70-R17 Tire Comparison - Tire Size Calculator | Tacoma World
315/70-R17 tires are 3.89 inches (98.7 mm) larger in diameter than 265/55-R19 tires and the speedometer difference is 11.3%

This says 11.3% off from factory

Mine is a 2013, so I started out with 18" wheels, but I don't know what the factory tire size was.265/55-R19 vs 315/70-R17 Tire Comparison - Tire Size Calculator | Tacoma World

Factory tire size for the GX460 is 265/60R18.
I was able to shoehorn in a 33x10.5 with no mods other than pushing back liners and removing the offensive bolt in the back of the wheel well.

I guess I’ll share my input. I have a total chaos/king setup on mine with 285/70s on 17x8.5 -10 scs wheels. It’s the best setup IMO. Tires aren’t too large that you have to regear and the wheels have just enough offset that you can put off a bmc until you’re ready to do heavier offroading. The 550lb springs are a little soft for the gx, but the adjusters help make up for that and you can set them where you want them. I’ve had no issues with this setup after 30k miles over the past year. I just grease the UCA bushings every so often.
What are folks' experience with SPC UPCs? That's what I originally went with, and the ball joints crapped out in a matter of 2 months. I've got Icon UPCs now, and they're great. I must have been reaching the limits of articulation with the SPCs, I suppose, but within a month or two, I could feel it in the steering wheel, and sure enough they were both shot.
I ended up with the BP51's with their mid range spring and the ICON UPCs. I have 33's, and just needed a heat gun to remold the wheel well liner near the body mount.
Also, I'd not think about suspension modifications as 'lift kits', even if they're sold as such. Folks think that they need a 'lift kit' to fit bigger tires, but that's backwards. You get bigger tires for more clearance of low hanging points, and then clearance the vehicle to fit those tires. There are no offroad race vehicles with a 'lift'. They have proper suspension geometry and just make room for tires that will clear whatever it is they want to run over

Ball joint life is very subjective and dependent on how they are used. I've seen brand new ball joints break on a trail when they are stressed beyond what they can handle. If you want the very strongest then go with a uniball style. They make noise and need replacement more often but less breakage risk.
My SPCs have held up great. They are the newer version with the greasable ball joint. Have a lot of friends with them, and no complaints.
