Recommended Suspension Enhancement For Dog Trailer That Rides Rough

Question

Question:

I have a 1600 pound to 2000 pound dog trailer that has a two and three eights 3500 pound axle. I would like to add some type of suspension to smooth out the ride considerably for the dogs. The trailer is all aluminum frame with a steel flat bar, bolted to the frame where the leaf springs attach. What type of suspension would you recommend and would be best suited for dirt roads?

Hey Tyler,

For a 3,500lb axle SuperSprings International has you covered with their SumoSprings Helper Spring line, you'll just need to see if the axle is above or below the leaf springs. If the axle is below the leaf springs you have an overslung suspension and need part # TSS-107-40. If the axle is above the leaf springs then you have an underslung suspension and need part # TSS-106-40 instead.

These jounce springs will provide a night and day difference for your trailer's ride quality and help keep the dogs comfortable on while traveling.

Hey Darrel, we actually have exactly what you are looking for with the part #TRU52FR which is for a 7k axle and is 25-1/4 inch from eye to eye. This is also a 6 leaf spring as well. The spring you referenced would be too short.
