No I got lazy and haven’t gotten around to it lol also if you bought your Rays pre tariff craze, you can probably make a couple hundred reselling them. I ordered mine back in November and had people willing to buy mine after I got them quite a bit over to skip the wait and after the price adjustments.
I'm still waiting for my set. Supposed to ship late July according to the supplier. Hopefully, you will have mounted your extended studs so I can make a more informed decision. I think I can make back the funds paid but I may keep them if you're able to mount them safely.
I will commit to at least taking the wheels off the rear tonight to see if it’s doable in a driveway without pulling axles lol fronts should be fine
Both the front and rear hub bolts are removed/installed with hand tools. Looks like it's straightforward if things aren't too rusty.
There's a SST for removal but it's interesting that Toyota's installation is how DIYer would do it with a washer and nut.

Instead of a washer and nut, there is a bearing tool that you can buy that will reduce the friction and the chance of you jacking up your new studs with too much torque: https://www.amazon.com/dp/B000ETUD2...GMOC0OJDG&ref_=list_c_wl_lv_ov_lig_dp_it&th=1
I was unable to find that SST in stock anywhere but I think I can get by using a ball joint press. DONT HAMMER OUT THE OLD STUDS WITH A SLEDGE because there is a non-zero chance that you will damage your hub bearings.
100% on the bearing install tool & not hammering the studs.
I just find it interesting that Toyota doesn't recommend a SST for the install since most recommend pressing in the studs as the official way of doing things
https://www.amayama.com/en/part/toyota/0965017011 - Amayama has the tool, shipping's a bit expensive but I'm probably going to order it since I have a bad habit of collecting tools I only use once in a blue moon.
Thanks for the link. I submitted an order! I like collecting single use tools too! Lol.
I think there are many who have installed the wheels on OEM studs and have not experienced any issues. I don't know if these vehicles have been mostly driven on pavement or have been taken off road. I would be in a world of hurt if I lose a wheel in the backcountry.
I would love for the ZE40X to be plug and play but it doesn't appear to be that way at the moment.

At the end of the day, its up to all of us to do our own research and decide what is best. No judgement here. I dont doubt that many of you are running OEM studs on non-ET drilled wheels without issue. However, I can say with absolute certainty that I would hate to be in the minority that does have an issue, especially if it results in property damage, injury, or loss of life. Also understand that insurance will deny the shit out of your claim if they determine that your vehicle was unsafely modified so you will be 100% liable.
After reading through a bunch of threads on various Toyota/Lexus body on frame forums, my sense is that the majority of aftermarket wheel owners are not replacing their hub bolts. Most are not having issues over several years. Interestingly the people who seem to have problems with wheels falling off/hub bolts snapping are those who replaced their OEM hub bolts with extended bolts.
I'm going to replace mine but not sure if I'm going with the KYO-EI or random ebay bolts that Tundra people have bought.
My super rough math suggests that you need 12MM of thread engagement / 8 full turns on a M14x1.5 bolt, close enough to the rule of thumb with lug nuts where thread engagement = diameter of the bolt.

Are those the Japanese-made ones from Blackhawk?
I suspect the wheels falling off are from not seating the new studs all the way. That would allow the lug nuts to loosen as the studs seat further into the hub. Just a theory.
Hey nsfw302, any update on your extended studs? Just got notified that my ZE40X order has shipped from Japan so should be getting them later this week or early next week. Still waiting for the extended studs from Japan.
I'm asking a local mechanic to do the install for the studs but wanted to know if it is a straightforward job. Thanks.
For those interested, I was able to install extended wheel studs from Kyo-Ei SBLC. Was able to get thread engagement of at least 9.5 turns. I used 112 mm to 95.1 mm hub rings but that precludes using center caps due to push through design.
There are no push in center caps available for these wheels. Next step is to use 106 mm to 95.1 mm hub rings to accommodate the center caps. I was running Method MR305 wheels previously and there were slight vibrations through the steering column at speeds above 70 mph. The hub rings have remedied this issue so I'll be sticking with rings going forward.
