Review on Rancho RS999297 RS9000XL Series Performance Shock by Justin Munajj

Purchased to replace the rear shock absorbers on a 2014 Silverado 4x4 Crew Cab. There are 9 settings to adjust the harshness of your ride. Settings 1-8 are useless. They don't even seem to have shocks. 9 rides softer than the original, but still too soft under any load. and you still can't load the quad/tow a heavy trailer (handy). Maybe with a single cab or a 4WD truck that doesn't tow they would be great.
