Front SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to stabilize weight transfer and limit body roll while decreasing vibration, stabilizing sway, and softening harsh rebounds. 

The SSF-604-40 has a 1,400 lb capacity when compressed at 50%. The Blue SumoSprings shouldn’t be compressed past 70% of their original height in order to keep full memory rebound.

Please Note: SuperSprings International products are specifically designed for vehicles equipped with factory suspension. We cannot guarantee their compatibility with aftermarket products or parts. For questions about fitment on your specific vehicle, please contact us.

They made the suspension feel more responsive and raised the body sag.

These are great. Super easy install. I am running the front and rear bump stops along with an ICON stage 4 suspension set-up with 285/70R/17 AT tires. A week after install I took the 4Runner to Big Bend National Park and ran the back roads that had numerous whoops and washboards. These bump stops are awesome. Made the rebound of the suspension smooth as butter. I was running these back roads between 30-40mph, and the 4Runner stayed “planted” and I never felt as if there would ever be a loss of control. If you are on the fence about purchasing these, purchase with confidence. Ordering was simple and the shipment came sooner than expected.

These are great when going off the beaten path, no more creaking and groaning over washboards. Speed bumps? Smooth as silk. The runner flows over bumps, potholes, and washouts with ease. Love these suspension upgrades!!!

I give my purchase a 10/10 as products work as specified which is great. The front kit is great on and off road acting as bump stops. However, the rear is really stiff(airless airbag as advertised) which is great for road control and anti towing sag. Not so good off road though. Would be nice if there was a kit for the rear to act more as a bump stops instead of airless bags. Both kits are fairly easy to install with only a couple tools. Kits seem to be universal fit so some bolt cutting on front springs may be required depending on your application.

Easy installation. I now have Sumo Springs front and rear. Great for driving and towing. Eliminates trailer sag and nosediving on rough roads. Highly recommended!
