68% less G-force vibration.

Trailer Better.

"I love how they feel compared to towing without them. The amount of control the truck and trailer have combined is mind blowing with them. Construction sites generally can feel squirrelly with all the uneven pavement but the reduction in tip and roll really helps keep the trailer tracking flawlessly behind the truck throughout the transitions. These should legit be standard equipment in my opinion."

Two applications. Enough to cover just about every trailer out there.

Trailer SumoSprings are manufactured from our micro-cellular polyurethane. Designed to remove sway, hop, & vibration, this zero-maintenance airbag alternative increases overall driver control and ride comfort when towing.

If your towable has axles with a weight rating of 5,000lb or greater, you'll need the black (-47) option.
This will you give you the best load support and control.
