Cosa dicono i nostri clienti

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 and super easy to install. I’m running front and rear bump stops with an ICON Stage 4 suspension and 285/70R/17 AT tires. A week after install, I took the 4Runner to Big Bend National Park and hit back roads full of whoops and washboards. The bump stops made the rebound smooth as butter, keeping the 4Runner planted at 30–40 mph with zero loss of control. If you’re on the fence, buy with confidence—ordering was simple and shipping was faster than expected.

I bought these to help my 2021 4Runner tow my 2022 Airstream Basecamp 16X after my airbags failed. The difference was immediate — the springs greatly reduced sag and improved overall stability while towing. I can now lift the trailer off the ball even on unlevel terrain without struggle, and the ride feels more confident and secure. They’ve truly transformed my towing experience.
