You spend your money, others can spend theirs.
Has anyone had the dealership recalibrate or point the headlights after the 24 to 25 spring modification? or radar/sensors?
I have not
had it done at an indie toyota shop. they calibrated sensors but i did the lights myself.
have them a bit lower than stock so not to blind oncoming traffic.
dealer wanted $2800+tax for the install + msrp for the springs.
got the springs for 15% less online and a shop that specialized in yota lifts did the install for $800 including alignment and sensor calibration.
Thanks, I'll ask them to calibrate them for me if they didn't when they installed the springs. I'm surprised it needs it for that small of a change though. In my Rivian, the suspension goes up and down by quite a lot (several inches) depending on the height you choose when driving, and I guess I don't think that the lights or sensors change in any way when that happens (but perhaps the software is smart enough and adjusts when the height changes on the fly). Also, just the vehicle bouncing around on the road would seem to be more varied than a 1" spring height change, so I wonder about it. However, I'll ask them to do it.
Thanks again for the reply, I appreciate the feedback.
They may have already done it when the dealer did the swap for me. Did you have to ask them to do it or did they just do it in the ordinary course?
the car still works without calibration. everything is just a bit off. mostly it can't tell the distance to obstacles correctly so collision avoidance and adaptive cruise are off. i noticed way more emergency break/collision alerts before the calibration.
when you lift/lower all 4 (like the rivian), you don't need to adjust the lights. the other sensors probably take it into account. but when you lift/lower the front more/less than the rear, it becomes an issue for everything.
also, alignment is critical. toe will be way off after any lift on an IFS.
but, i guess that is a given. never heard of any dealer that does suspension work without also doing wheel alignment.
I didn't know to ask about the calibration. The tech told me they did it when I was picking it up.
The lift on the GX550 resulting from swapping the the front/rear springs from '24 to '25 is the same. the whole car is a bit higher, but the difference in front/rear height is the same. I measured it. Not saying calibration isn't needed, but that wouldn't be the reason.
Refer to this post for measurements:

Update: Dealer checked sensor/light calibration today when they were doing the "transmission rough shift when stopping" update (which it fixed by the way). They aligned the wheels when doing the spring swap as expected. So, I'm good to go.

Thinking about doing this to level out the truck. The more I see the 2025s the more I dislike the “raked” stance on the 2024s
The 25’s seem the same front/back just 1” higher. You could just swap in a 25 front springs if you wanted to level it.
In that case you would be changing angles so headlights probably would need an adjustment
When I search the part #s from the OP the front says “2025 coil spring” and the rear says “2024-25 coil spring” leading me to believe the rear spring is identical. Is that the case? If so, I would definitely only swap the fronts

The rear spring on the 25 is definitely different than the rear spring on the 24 I and others had. If you look at the measurements that I posted, you can see that by swapping the 25 for the 24, the car goes up about 1 inch front and rear.
I get that the leveling of the vehicle makes sense. What about heavy loads; would think there has to be an advantage to a higher rear so the vehicle is level if you are hauling weight or a trailer-
