Question:
I have a question about the SumoSprings solo custom helper springs product number ssr-307-47 and product number ss97uj. The mounting system looks to be the only difference and why did they change it? Thanks Russ

Expert Reply:
Yeah, those two kits use the same SumoSpring, the real difference is the mounting hardware. The # SSR-307-47 is the older design, while the # SS97UJ is the updated version with a revised bracket setup. SuperSprings changed the mounting system to make the installation cleaner, improve fitment on newer chassis, and get more consistent engagement between the spring and the axle.
Performance-wise, you're not gaining or losing anything. The spring itself is doing the same job in both kits: controlling squat, reducing sway, and helping stabilize the load. The newer bracket design is simply a better way of mounting the spring to the vehicle. If both part numbers fit your application, I'd lean toward the # SS97UJ because it's the newer kit and benefits from those mounting improvements, but you're not looking at a difference in load support or ride control between the two.
Oh and to answer the other question you sent in, the listed weight rating is for the pair of springs.
