SuperSpringsSSR-117-47 | SumoSprings Rear Solo for Ford F-150 | Left/Right Pair | 1500 (lb) Capacity at 50% Compression | Made in the USA, black

This product installed quickly and performs as advertised. Provides additional support when loaded while maintaining a smooth ride unloaded. I did not use the second acre on my install.

Installation:The SumoSprings were very easy to install. Total install time was about an 1 hour on a 2013 F150. The location and difficulty of removing the factory bolts was the only issue that added to install time. Removing the rear wheels before install would be advisable.Performance:The SumoSprings definitely increased the ride height of the truck when hauling. I installed these to counteract the tongue weight of the travel trailer that I haul (about 800 lbs). Without the springs there was a lot of squat and dolphining when towing even with the weight distribution hitch. After I installed the springs the squat is minimal and most of the dolphining is absorbed by the springs while towing. I can't speak on any sway or stability performance increase while towing because I never experience a problem without the springs. Sway control was not an issues, and continues to not be an issue with the SumoSprings installed. Overall, I am very impressed by how much these springs changed the performance of the truck. I am very pleased.Unloaded:There is no identifiable, negative change to the truck when unloaded that I can notice. In fact, the only two attributes that I feel might have changed are positives. I believe the truck absorbs shock from bumps much better. What was once rattle and clatter is now a thump and dampen experience that is quite noticeable. The other change is body roll. The SumoSprings noticeably react while cornering to counteract body roll. The truck is much more stable in turns, and I can only assume that provides added stability while towing. I enjoy that it did not change ride height and did not stiffen the suspension.SSR-117-47: I ordered these because they are rated at 1500 lbs. The other springs on Amazon are rated at 1000 lbs. These did not show they were compatible with my truck from Amazon. However, they were the model number that was recommended by the SuperSprings website. I had no fitment issues. Not to mention the price was unbelievable!Conclusion:Extremely happy. I had some reservation with the bump stop replacement springs not being able to provide the additional support I needed. I wanted to increase ride height while towing, and my concern with the SumoSprings is that the 1500 lbs was not available until the springs were 50% compressed. I was afraid that the squat was still going to be present with these type of springs. This could not have been any further from the truth. The SumoSprings dramatically increased ride height, and performed flawlessly for what I wanted. I am highly recommend these towing applications.

Very expensive for what you get but they work very well

2020 F150, Borla Attak Dual Exhaust and Hellwig Rear Sway Bar. This combination causes the bar to hit the exhaust over large bumps or if the truck is loaded which mine is often. Spoke to hellwig and they said, oh yeah it doesn't clear with a dual exhaust. I try 10 different adjustments and nothing worked. Then I thought up trying suno springs as they prevent sagging. Since then I have adjusted the system as tightly as possible. Have no hitting and issues. Also truck is more controlled when heavily loaded. Didn't affect ride besides a tiny bit of bounce if you are on the back seats and the vehicle is max loaded going over bumps. These will be in every truck I get moving forward.

Great product and easy to install, although the first removal (right side) took 4X the time…not a product issue but one side took SIGNIFICANTLY longer to remove. Total time to remove/replace left (2nd) side was about 8 minutes. Have not driven with trailer yet but looks like it’ll work great to limit “sag”. I used it on a 2018 Ford F-150 Super Crew 4WD. Did not use the optional spacer because it would have taken out all movement. Ended up with about 3/4-1” movement prior to SumoSpring engagement. All in all, great product. I will update if not great with trailer attached.
