You'll be happy with your choice. Rough country is great quality stuff. I don't care what anyone says. There's also some youtube videos on the install but it's pretty straight forward. I've even towed with the kit. I have a 5500 lbs travel trailer. Barely even sags in the back with this kit...
Rough country has been making shocks for off road since the 60s and springs since the 70s. If you want expensive then spend top dollar. But Rough country is good stuff.
