So I need to replace both upper and lower ball joints on my truck as well as the hub bearing on the passenger side. Truck is a '13 Z71 1500 and currently has 100,000 miles. Has had a CCM 2.5" level on it since about 10,000 miles. I know I've seen some guys use the Cognito UCA's to level their trucks without using a leveling kit at all. I guess my question is should I do away with the 2.5" CCM kit and use the Cognito kit alone for leveling or can I keep the CCM kit and run it with the Cognitos? And are the Cognitos worth it for the $500 they cost? The truck is equipped with the factory Rancho shocks as well if this helps.
