I run the HD TC's on mine (6.2, Ramsey 9k, custom bumper). I previously had Skyjacker softrides on it (prior to the winch and front bumper) for about 6-7 years with no obvious sag. The TC HD's are factory rated slightly softer than the Skyjackers were, and gave me the same ride height but a slightly softer ride.
Anyway, get the HD versions...............they are the same as the EZ rides with the exception of an extra leaf, and all for the same price. Put the HD's on and if you think it's too stiff just pull one leaf out and they will be EZ's.....
