ICON engineers have also developed optional "Performance Systems" that include multi-rate rear coil springs in place of the rear spacer. The lighter initial droop rate of these performance rear coil springs helps the truck feel smoother and more controlled over washboard roads, small whoops, or similar terrain. The secondary ride rate allows the truck to maintain exceptional ride quality, while the aggressive third overload rate helps prevent bottom outs and provides payload support. These systems were developed with the chase truck type of application in mind, and will significantly increase the on and off-road performance of the RAM 2500 when driven aggressively.

• Vehicle specific design yields .5" of rear lift on Ram 2500 equipped with rear coil spring
• Triple rate rear coil springs with ICON-engineered droop, ride, and overload rates
• Significantly improves on- and off-road ride quality and performance over stock
• Rear extended length shocks are recommended for complete installation
• Durable powder coating for corrosion resistance
• Lifetime guarantee against sagging/breakage
