Expert Reply:
Between the SumoSprings and the Timbren kits for your 2015 GMC Sierra 1500 I'd go with the SumoSprings # SS95MR as the Timbrens are notoriously harsh when the truck is unloaded.
That said the best option is the RoadActive Suspension kits like the part # RAS54FR for if you have a non-Denali or part # RAS2611 for if you do have a Denali with the Magneride. This gives you the support of the best systems out there while improving ride quality and stability so it's definitely the best option.
