Product Description

Firestone Coil-Rite Air Helper Springs Firestone air helper springs are designed to fit inside existing coil spring suspensions, creating a variable rate spring.

I installed these in my 2006 Toyota 4Runner because I tow a 3800# camper about once a month and past experience taught me these help make the road trips more comfortable. It took me half a day to get the kit fully installed but having owned an Airlift 1000 kit on a previous vehicle I can say I am much happier with the fittings on this kit. Push the hose into the fitting as deep as it will go and then pull firmly and done. No leaks and that is a big deal. I do wish there was an included T connector so I didn't have to run two separate valves but that is just a preference and barely worth complaining about. Bags are nice and thick material, hose is more than long enough with extra to spare, and everything necessary was included in the kit.My first trip out loaded up with the family I had only 10 PSI per bag because there was no sag in the suspension and I figured I didn't need the kit until we got about halfway to our destination. You could feel the road's imperfections clearly so I pulled over and aired the bags up to 20 PSI (30 PSI max) and that made all the difference. I keep it at 10 PSI for unloaded driving because it isn't recommended to deflate the bags and at this pressure they have plenty of wiggle room in the coils but when it comes time for hooking up the camper it takes me all of 1 minute to inflate both bags to 20 PSI and tow off on another adventure in comfort.No, this kit does not add a lift, increase the max towing capacity of your vehicle, or replace the need for a weight distribution hitch. It does allow you to reduce rear sag so you can ride more comfortably and safely though and believe me for the price of this kit it was money well spent so I don't have a grouchy spouse and child to contend with when going camping.
