The 2013 4-Star Trailers horse trailer with 'Quiet Ride' technology. Noisy trailers cause unnecessary stress on your horse. The longer the haul, the more stress your horse endures. High performance horses are especially susceptible to stress related performance problems. It is not uncommon for horses to require 2 to 3 days of recovery time after trips as short as 600 miles! Do you and your horse a favor. Check out 'Quiet Ride' technology from 4-Star Trailers.
