24 vs 25 OT OEM 1” Lift Details via reddit

[ISU3GX]

Coil ETA was 4-6 weeks for the rears and 2-3 weeks for the fronts. They all arrived today, 6 days after ordering. So good news delivery much faster. Of course I hadn’t called my independent shop to schedule bringing the GX in since delivery was going to be mid July.

I’ll work installation plans next week.

Additional information. I had snapped a photo of a 2025 OT front spring at delivery and the color markings were white & blue. Same color markings on my new springs (48131-60U30). Looking at my 2024 OT shows front color markings as blue & blue. The 2025 front coils are just under 8 1/2 turns total.

Looking at the rear coils my 2024 has white/brown/pink as the color markings from the bottom up. My 2025 rear coils (48231-60Q00) show white/pink/brown as colors. I did not snap a photo of the rear coil on the 2025 OT I photographed. The 2025 rear coils are 7 1/2 turns total.

Free length of the 2025 F/R coils is 16 13/16”. The fronts and rears are the same free length.

Visual driveway inspection of my 2024 OT truck as-built looks like the 2025 coils have 1 additional turn versus the 2024 coils. The spring diameters similar. All things being the same an extra coil turn would result in a softer (lower spring rate) coil. But this wouldn’t provide lift. So, I suspect the 1” lift is because the 2025 coils are also taller than the 2024 coils. This would support @rovensail comment a few posts ago (#134) that there GX actually rides improved. If the coils have an extra turn and are longer this totally makes sense that the resulting ride would be softer.

Of course, once I have the 2024 coils pulled I’ll take some pictures and length measurements. This could actually be a case where lifting the truck could improving the ride?!?! Will share my thoughts once they are on.

Welcome 2025 OT owners advising if they see the same spring color dots on their front coil (white/Blue) and rear coil (white/pink/brown).

Hi, mine were installed today by Lexus of Nashville. Did a great job. Service guys were interested in the process (and the NYTOP bumper and sliders I had on it) so I think they paid some quality attention. Pics Left and Right with measurements pre/post, and a front view and pic of the old springs in the box. Got the expected 1" lift.
[EDIT: if someone wants the 2024 springs and can manage the logistics, I'll part with them for a bargain price. PM me if interested]

Cool. If you could, count the number of coil turns your existing springs have and also their free-length. My visual inspection says the 2025 springs have an extra coil turn.

I measured my 2025 coils and they are 16 13/16 inches tall. I’m expecting the ones that came off are shorter. Please measure and share if able.

Gracias.

Hi, I'll do that tomorrow and post a report.
