Hey Hiroshi, yes the SumoSprings Solo Custom Helper Springs # SS68DR are going to work with your 2024 Lexus GX 550 and won't require anything else because this kit come with everything you'd need.

Please feel free to let me know if there is anything else I can do to help!

Hey Hiroshi, how did the SumoSprings work out on your GX550? It’d be great to hear how the ride and support turned out after adding them. Your update could make it easier for the next person with the same setup.

@LazerS The sumo springs do what they say it will do but, you may need to cut them to make them fit correctly. Mine wouldn't fit in my GX550. Too long so I cut one lug off and it works good. When sitting on the springs, it does make the ride a lot firmer unless you have a real heavy load in your vehicle. Took it on a 3k mile boondocking trip loaded and pulling a travel trailer, no levelers because of some off road traveling. Sure saved the back end of the vehicle and tongue of the trailer going thru washes and ruts. I like them very much.

@HiroshiM I forgot, I gave mine a 2 inch clearance so it would ride noemally when not loaded. Makes a big difference.

@HiroshiM Glad to hear you are liking them! I definitely get not wanting them engaged all the time as well. They absolutely help when loaded and or towing, but can make the ride a bit harsh when you aren't. I hope they continue to serve you well! Have fun out there! : )
