Where To Route Air Line on 2021 Toyota Sienna with Firestone Coil-Rite Air Helper Springs
Updated 04/01/2022 | Published 03/31/2022
Question:
The rear springs have a large bounce-stop at the top and the bottom of the suspension arm that holds the coil spring is solid. How does F4155 install on this vehicle without drilling/cutting? It seems like youd need to cut off the bounce stop AND drill a hole in the center plug on the coil spring mount to route the air line.

Expert Reply:
I checked with Firestone and confirmed the Firestone Coil-Rite Air Helper Springs part # F4155 for a 2021 Toyota Sienna (FWD). It looks like we have installed a few of these kits on some older models, in these the air line went through the top of the spring mount. I don't show any obstructions in the way but if you do have any then you make need to make an opening, you shouldn't have to drill through metal or anything though.
