Fantastic bump stop replacement. Significantly increased the comfort of my ride while still maintaining good articulation.
Vincent Lo –
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.
Robert Zarate –

I installed the rear ones 2 months ago. No more sagging wend hauling my travel trailer. Now, I just installed the front ones. No more nose dipping when braking. Did not go off road yet so I can’t comment in this regard. On the road, the truck behaves less like a boat. Ride is slightly more rough but it is preferable than sagging and diving. Great addition but VERY EXPENSIVE for what it is. I have a Tacoma 3rd gen TRD OFF ROAD wit a TRD lift kit (1″ lift at the back and 2″ lift in the front). If it was cheaper, I would have give it 5 stars.

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!

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.

Eric Romero –
All good, love the quality and benefit of your products
Ronald Hall –
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!!!
James Vignali –
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.

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