Thomas Thompson –
I utilize the SumoSprings (Heavy Duty) on a 2014 Chevrolet Silverado with 120k+ Miles, an ARE truck topper, long distance road travel and towing/hauling at max GVWR. I have utilized ‘leaf helpers’ on previous work trucks, but this is far better for a daily driver. The body roll/‘Cadillac’ sway is removed and the feeling of a stabilized rear end (towing with a weight distribution hitch) is very noticeable and desired. When loading the rear end, you don’t get the hard bump stop feel and bottoming out to the ‘pig’/rear end as with a stock bump stop.
I utilize the SumoSprings on the rear and the Coil SumoSprings on the front. It will change the trucks feel and ride to a much more desirable ride, if you tow/haul and just as a daily driver.
I’d recommend these products to anyone with novice installation experience and as a ‘must have’ upgrade for the life of a truck, out of the box/factory. Worry free; Always nice when traveling and towing/hauling for a long 4+ hour trip away from home.
*Great product with easy installation and maintenance free.

As a welder, with approximately 800 pounds in the bed of my Sierra 1500, the rear yellow sumo springs lifted my rear end completely, eliminating body roll. It made the truck feel significantly more comfortable while taking corners on country backroads. When I added the front helper springs, the only thing I can say is if you don’t have them, you’re missing out. 10/5 stars 100%
