It depends on what you're looking to do with the mod. The lift kit will actually raise the bike by the amount indicated on the kit. Ride will be pretty much the same. The HL springs don't technically add lift. They are the same length but stronger than stock so they don't sag as much under load. They will add about 100 lbs to the weight capacity of the bike with a resulting increase in ride stiffness.
Another popular option is the Perfex Long Travel Suspension Kit. It gives 1" to 1 1/2" of lift plus softens the ride. So what you add first or at all depends on what changes you are tyying to make in your bike.
