Rear SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to reduce rear-end sag and increase load carrying ability while decreasing vibration, stabilizing sway, and softening harsh rebounds. 

The SSR-330-47 has a 900 lb capacity when compressed at 50%. The Black SumoSprings shouldn’t be compressed past 65% of their original height in order to keep full memory rebound.

Huge difference in driving quality between the stock bump stop and sumo springs. We went from bumpy ride and feeling every pot hole to better ride quality. Before the sumo springs every high wind areas we passed I have to slow down and manage the steering wheel continuously, After the install, it's much stable and resists cross winds immediately and consistently adjusting the vehicle position in space. Probably the best investment I put on our 2020 Airstream Interstate 19.

Shipping was fast and received parts in few days to Toronto Canada, waiting for a warm dry day to install the complete systems

Absolutely amazing!!!! The ease of install was quick and to the point. The ride quality and handling has improved 150%! Thank you for giving us a way to have a much smoother and less tippy vehicle. If you own a Sprinter Van you need these!
