W8006413-P - Front Suspension Air Bag Inside Coil Spring Kit (Pair W/ Air Line & Fittings)

The W8006413-P is a pair of air bags that go inside your front suspension coil springs.

Yes, those would be the correct airbags for your RV . 

Minimum air pressure is 40 PSI and maximum air pressure is 90 PSI. You will want to set the pressure based on ride height. Optimal ride height is between 1.75"-2.5" measured from the top of the lower bump stop to the bottom of the frame where the bump stop would make contact.

These were factory installed, their purpose is to adjust the front ride height for proper steering geometry.

Hello Mike, there are two options for those, one way is to basically cut and tear the old ones out, then squeeze or vacuum out the new airbags , use soapy water and work them up through the hole in the lower control arm. I have heard of using zip ties to compress the bags to try to make them fit up through that hole as well, The other way is to drop the lower control arm down and remove the coil spring, replace the airbag and re-install . I've done both and found it just as fast to remove the coil spring, although that does require big jack stands and a good floor jack . Backyard method would be working it into place from below, not easy as there are also plastic discs, that go on top and bottom of the bags .
