SuperSprings SSF-604-40 Pair of Left and Right Front Blue SumoSprings fits 2000 2005 Tacoma Tundra 4x4 | Decreases Vibration, Stabilizes Sway & Softens Harsh Rebounds

Expensive but well worth it

I recently installed the SSF-604-40 SumoSprings Front on my 3rd genToyota Tacoma, and the difference has been fantastic. With a robust 1400 lb capacity at 50% compression, these springs provide excellent support and stability, making a noticeable improvement in ride quality and handling. The most significant upgrade is how much more pleasant bottoming out has become—there’s a smooth, controlled response rather than the harsh jolt I used to experience. Installation was straightforward, and the fact that they’re made in the USA assures high quality and durability. Overall, these SumoSprings have exceeded my expectations and are a great investment for anyone looking to enhance their vehicle’s performance. Highly recommended!

Had to cut half the thread off before I could attempt to install it. Original bump stop thread was as long as what I ended up with. Truck jacked up to give the most room for install I still had to tap it in compression of the sumo spring on one side of it to align it to thread in. Both installed this way. End result they are in compressed one third when parked (always touching) however the ride has improved. My guess there more universal size for vehicles.

I've had these on every truck I've owned, but in the rear. I decided to try a set on the front of my 4Runner. It already has a set on the rear. I off-road the vehicle regularly so they offer a bump stop and an improvement in ride quality in general. If you're installing these on a 5th generation 4Runner, you'll need a huge set of pliers to remove the stock stops. You could install the Sumos in two ways. The right way is to lower the lower control arm. The other way is to cut off about 1/2 inch of the threads I order to squeeze them in.I haven't put a lot of miles on them, but as usual I like them. They're a great alternative to airbags of you tow, traditional bump stops if you wheels, and if you've removed your sway bars they can help the truck not feel like a trophy truck on the road.My only gripe was that the threads on one were a little boogered up. I just ran a thread chaser down them and all was good.

2023 Tacoma. Fits no problem. Dont have to cut bolt as other reviews said. You can but not needed. You have to lift the front end up. Tire off ground. Enough room to install. I have front and back installed. No more squat with bed full of wood. I would purchase again.

Even with the suspension fully extended on my 2020 TRD Sport, I had to cut the bolt about 1/2 an inch. Thank goodness for angle grinders. Unlike the factory setup, this provides preload on the front all the time. Lifts the front about 3/4 of an inch. Cutting the bolt was a pain, but they work great otherwise.

I have the ones in the rear. I DO help keep the truck from squatting and roll. Good.

This solo sumo spring is just too big. I have a 2000 tundra 4X2 with a 1” leveling kit and installed these for the front end. I replaced the forward bump stop to avoid working around the sway bar and tie rods plus the forward hinge on the lower control arm is wider than the rearward hinge. The bottom bolt of the strut tower is also factory installed this way. Now, to make them fit, I literally cut off about two thirds of the installation bolt and pushed it in at an angle while the truck was jacked up off the ground. Once installed, the spring was already compressed about halfway between the frame and lower control arm on the backside without a load which made the ride tight and bouncy. So I took a hacksaw sawzall and carefully cut off the lowest layer (donut). That was what it needed. Now the back of the spring barely touches the control arm on the backside while unloaded and feels way better driving. Once installed after these modifications, I get the front end support boost I wanted without the damn bounce and it feels great with a lot less of the notorious sloshy boat ride (yes, the struts and shocks are brand new as well as the ball joints in case you’re asking).
