I installed these under my Firestone Ride Rite "Red Label" air bags on my 2017 Ram 3500 4WD SRW diesel truck. (Firestone kit #2705) I take my truck on trails & overlanding trips quite a bit and I immediately knew I needed these when I discovered they existed. The airbags get stretched and greatly restrict the rear axle's articulation - as well as increasing the risk of damaging the bags. Installation for my setup was quick and easy. I let the air pressure out of the bags, unbolted the U bolt holding the lower bracket to the axle. Then removed the one bolt holding the bottom of the air bag to that mounting plate. Compressed the airbags up out of the way. I then bolted the Daystar cradle to the mounting plate with supplied nut and bold & then that plate back to the axle with the u-bolt. Took about 20 minutes to install both cradles using only a 9/16" wrench and 9/16" socket wrench. The added cradle is thick and with the suggested 5lbs psi in the bag it lifts the rear of the truck up about 5/8" without a load. So I keep the bags deflated when not towing or hauling. Truck rides nice and getting my rear axle's articulation back while retaining the airbag system is the best of both worlds. So far very happy with these and will update after a year or so of use.
