Product Information

Firestone Ride-Rite air bag helper springs are the work horse of the Firestone line. The double convoluted air bags offer maximum load support as well as years of worry-free service. These are installed between the frame of your vehicle and the suspension, providing load support through the use of air pressure. Specifically designed to maximize the safe load carrying capacity, stability and ride quality. Will also reduce the suspension fatigue on leaf springs caused by permanently sagging. An optional air control kit (air compressor kit) can be added (not required) for additional convenience.

    great kit and easy install
    I used this on my 2011 f350 diesel and i love it so far. it really helps my towing and also helps my ride quality. i have no more drag while hauling my 31 ft. camper trailer. keep in mind the camper is around 11000 pounds and it handles like a champ.

    Really good kit, i only had one problem, that was the install time, it took me about 2 1/2 hours. I think its just because i was new to this, if you have a better idea, you should be fine. other than that. great product.

    Firestone helper air bags
    Some hardware for this kit is NOT a direct fit. The upper bolt on the passenger side air bag mount is too long and the end of the bolt bottoms out on the Ford factory installed under bed fifth wheel before it tightens up all the way. You need a thick washer or shorter bolt, so be aware in case you try to put this kit on and use it the same day.
