Hello, just purchased 2026 TX350 and looking to purchase Grand highlander running board and Mudguard from Toyota as they currently have sale going on. Can anyone confirm if they fit TX350 who has already done that? Thanks a lot in advance.

 

Why dont you buy it and let us know.

 

If you have the part numbers, there is probably a reference if they are cross compatible,

 

Yup, they fit. I got the highlander running board from a Toyota dealership as they were having online sale new customer for 10% off + mothers day 15% off. They're the exact same part # as for the Lexus TX. However the mudguards/cargo trunk lamps are different part numbers.

Running Board Part # - PT938-48240 for TX/Grand Highlander
Mud Guards Part # - PK389-48R00-TP- Grand Highlander
- PK389-48R50-P1/TP - TX

 

Does the running board block the pinch welds and jack points along the side of the car where it is safe to place a jack to lift the car?
I usually change my tires at home (summer / winter tires) but from pictures I have seen, it's hard to tell if the dedicated area to safely lift the car is blocked by the running boards.
I would like to get running boards in the near future, but if it's something that will be an inconvenience while using a pump jack to change the tires, then I'll have to reconsider getting them.

Does any one have pictures of the running boards installed and under the car to see the pinch weld/jack points?

 

Just took some quick pics for you. You'l need some sort of jack pad extender or a block of wood to clear the running boards. There are front and rear jack points on the subframe, so you can lift the front/rear and place it on jack stands no problem. But if you want to jack from the side, you definitely need extenders to clear the running board.
