Hi all, technical and purchase question for those with a rear air bag delete (I am not a hard-core off roader and 90% of driving will be on paved road. I just want to be prepared for overloading and occasional bumpy adventures as I get into "embracing nature"):

- how important is having the top secondary spring (cone) as part of the air bag delete? Some of the air bag delete kits don't include it, or include it as a "stage". I know that in the 4Runners (which the GXs are closely related to) they have these cones as standard in their rear spring setup.

- if I do get cones, is it OK to get the Toyota OEM cones versus the aftermarket cones? The cost difference... is almost 3x. OEM cones cost about $80 and some of these aftermarket cones are like $200+. I know they have their technical differences, but for the most part, if the OEMs are good enough for a 4Runner, then I should be OK with them no?

- how many of you also switched out or cut down the rear rectangular bump-stops as part of the air-bag delete? I was thinking about replacing the GX bump stops with the 4Runner bump stops which are shorter. Metal Tech 4x4 has a video saying to cut the GX bump stops because they are too long and were intended as resting points for the air bag system.

Thanks in advance!

(will be cross posting on the GX470 thread so apologize for the posting/spamming)

I deleted Airbags and Put in the Bilsteins 5100s and Moog Springs- You will not be Disappointed.
I would add the Energy Suspension Cones. I did not and Regret it.
Added the Air Springs to Firm up Rear Suspension as needed.
