Customer Q&A - Firestone W237604174


Will it fit a 2011 Rave 4 V 6

Asked
Yes, Firestone Coil-Rite kit 4174 will fit a 2011 Toyota Rav4 V6.


Hi Is the maximum pressure for these air bags 35psi? thanks, Adam

Asked
Yes, the operating pressure for Firestone air bag kit 4174 is 5-35 p.s.i.


G'day mate Just looking at this Firestone air bag for a 2008 Toyota prado in Australia with a 2" life and how much would it be to ship to Australia Thank for your help

Asked
Our air bag kit applications are for North American vehicles. Many of the Firestone Coil-Rite kits do cross over to vehicles in Australia. To make sure the air bags will fit, we recommend measuring the inside length and width of your coil springs. The air bags should be as close to these dimensions as possible. The air bags in kit 4174 are 4 inches wide x 6 inches tall.
