It would allow you to adjust your ride height to your liking. Also, it should allow you the ability to change your spring rates as well.
The reason no one makes coilovers for the 2WD's is because, Dodge in their infinite wisdom, decided to go with a traditional shock and spring combo for the front suspension. They should have just used the same suspension for the 2WD's as the 4WD's like most manufacturers (that have a brain). Would have saved engineering costs as well as tooling...
To make a coilover setup (that is worth a damn) for the 2WD's, you would either have to drill the stock coil buckets to give the coilover hat something to bolt to and weld in a couple of shock tabs on the LCA to give it something to mount to there, or do it right and cut off the stock coil bucket and build a shock hoop for the coilover and re-engineer the LCA specifically for coilovers, but at that rate, you might as well go LT.
