Carli Starter System With BilsteinsThe Starter System is a great system for daily on-road encounters and moderate rough off-road. Not a racing system. The only con for the system is a rear hop when encountering higher undulations. Hitting whoops, it hugs the mound at low speeds and feels good.

Kore Chase System With Fox Shocks
Stiffest ride on-road and off-road. Not as smooth of a ride for your daily driver, but when your drive takes you over rough patches of freeway or expansion joints, it shows great control. Speed bumps and undulations are handled very well: no or little rear wheel hop.
Off-road, the system shows great control, steers great, but still, a stiff ride. This suspension likes to be driven hard and fast.
I'd recommend the system to those who like to drive their truck over really rough roads at high speeds. Control is this system's priority - comfort is second.
Note: Truck is running E-rated tires. I believe switching the truck to a D-rated tire will soften the ride, or run Es at a lower air pressure.
Kersten Pankatz's '04 Dodge Ram 3500 with 35-inch Toyo M/Ts and KORE's Chase system. Although the ride is firm compared to the Bilstein-equipped Rams, the cornering and handling are awesome. This system is for the off-roader who drives his truck to the trail. You get sports-car handling in a 7,500-pound package. | 
James Miller's '05 Dodge Ram 2500, equipped with 35-inch Toyo A/Ts and Lorenz Industries' Bilstein 5100 Series system. It is similar in ride quality to the Carli system, with a little more sway in the turns. This suspension seemed to offer a softer freeway ride, but that is most likely due to the softer D-rated tires. This is a great all-around suspension that will take you on and off the road in comfort. | 
Kevin Collins' '05 Dodge Ram 2500 is outfitted with 35-inch Toyo M/Ts and Carli Suspension's Starter System. The Bilstein shocks provide a great road ride and good control off-road. This system is recommended for drivers who want a smoother ride on pavement and good off-road ability. |
Lorenz System With Bilsteins
My favorite all-around ride. It handled the expansion joints the best, keeping the truck fairly level with little bounce. Very little sway in high-speed turns. Steering felt good. Some wheel hop in the undulation test. Off-road, it felt similar to the Carli. A little more control in the rough stuff.
I recommend the Lorenz if you're looking for a great all-around suspension.
Note: The Lorenz truck is running D-rated tires. I believe running Es will stiffen the ride and affect its handling, perhaps producing a harder ride.
Carli Starter System With Bilsteins
Softest ride of the group. Very comfortable for city driving, freeway cruising. I felt more bounce on expansion joints. Fast, winding roads felt loose, as if it needed more sway control.
Some wheel hop over undulations. Good control over the rough stuff. Good ride off-road. Steering was good. The suspension seems to float, making the ride more comfortable, yet it loses some road feel/control.
I'd recommend the system to those who drive 70 percent pavement, 30 percent off-road.
Note: The Carli truck is running E-rated tires. I would not run this system with D-rated tires, as the ride is already soft.
I think if we did this over again with the three systems, but matched with equal tires/trucks (i.e. stick versus auto), the results may have been a little different but not by much.
Although any one of these systems will improve the ride of your truck, each does have its own style of comfort and handling. Contact the manufacturers and ask if they have done any installs in your area for you to test-ride. Or join those guys from Northern California when they host their next Suspension Day!
