I see that the previous gens had aftermarket options for full-strut-replacement airbags, but I haven't found anything but lowering kits for 4th gen, such as AirRex and D2 Racing, both of which are a bit pricier than I want to pay. And also the kits appear to be 4-wheel only, whereas I'm only after the rears. (Suspension help for towing) The only other product I've come across is the Firestone Coil-Rite Air Spring kit, which is MUCH more reasonably priced, but I'm really not understanding how it functions. Anyone that has these, could you tell me how they do in compensating for loaded sag?
Firestone Coil-Rite Air Spring kit is a rear suspension helper kit so when I tow my bikes the rear of the Prius drops.. I just add a little air to raise it back up. Its a DYI install. I always like to use separate air lines to each back instead of splitting one line into two. It is a little tough but not bad folding the air bag and pushing in between the coils to get the bag on the inside of the coils..
