Question:

I had a question about the Firestone Coil-Rite Air Helper Springs Item # F4175 for a 2019 vw atlas. So my bags ripped or popped and want to know could I buy replacement bags and not the whole kit?

I reached out to Firestone and the air bags used in the # F4175 are not available by themselves.

To replace them you'll need an entire new kit # F4175.

The most common reason your bags would both rip or pop is due to under inflation. They need to have a minimum of 5 PSI air pressure at all times, so it's recommended to double check the air pressure every month. A 10 degree change in weather can change the PSI in the air bags by 1 PSI so if you're really keeping them at 5 PSI I'd be checking them sooner than every month.
