I would like to first make it be known that super springs customer service is top notch. We had an issue with shipping and they immediately took care of the issue. Installation of the sumo springs on a 2021 4runner was very simple. I was able to try them out today and they seem to perform well. They still allow my suspension to articulate when off roading but definitely helps with stabilizing the ride when hauling my cargo trailer. The only concern I have is that the sumo spring didn’t line up perfectly with the axle, it just didn’t have enough adjustment to get it perfectly lined up. I honestly dont think this will be an issue though.

Very nice product and smooth ride. Easy to install when you have the right tools. For the fronts, I needed to purchase a large pipe wrench to remove the OEM ones. Highly recommended.
Justin Morgan –
Looks awesome. Can’t wait to try them out. I am looking to soften out the hits when my shocks are are almost fully compressed.
Mike Mikac –

Matt Spelman –
They do exactly what I wanted them to do, and that is to support weight when I need it.
Jeffrey Lee –
Great product, already made a second purchase for my other vehicles

Very helpful when I had questions and I was impressed with knowledge and expertise of your staff. Shipping was on time. I have yet to install the sumo springs and plan to do some right after the new year

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!!!

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.
