There is NO equal, and there is NO compromise on quality! Teraflex has taken it to the next level with the Falcon series. There's no valid reason to compare the factory components to the Falcons either, it just makes sense, upgrade now and be done. They are rebuildable so it's literally the last set you will have to buy! Installation couldn't be any easier, really no different than installing any other set, they just look way cooler!
