Could Air Lift Coil Rite Kit for 2016 Toyota 4Runner Install without Removing Coil Spring

Question

Question:

I have a 2016 4Runner and I don’t have a lift, only a jack. Was thinking about trying to pinch the bags down somehow and squeezing them into the spaces with upside down installation after trying to cut the top rubber bump stop off. Is this able to be done? I don’t think I’m capable of disassembling the shocks as the video shows.

If you are able to cut the jounce bumper of your 2016 Toyota 4Runner off while leaving the coil installed on the vehicle you certainly could fit the air bag between the coils to install the # F4135 since this is commonly how it's recommended bag kits like this get installed.
