G, Yes both the Hellwig EZ-990 Helper Springs # HE67FR and the SumoSprings Solo Custom Helper Springs # SSR-117-47 can be used together.

The SumoSprings will replace the factory bump stops, and the Hellwig bolts above the factory leaf springs so the two won't interfere with each other.

The main difference between SumoSprings part #SSR-117-47 and Timbrens part #TFR1504E for a 2017 Ford F-150 is ride quality and support. The Timbrens are stiffer so they provide more support but this also means there is not as much give so the ride…
