They combine multi-stage valving, a large-diameter body for heat dissipation and nitrogen charging to reduce fade during repeated use. Durable construction and vehicle-specific tuning mean you get predictable handling whether you're towing, hauling or navigating rough terrain.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these shocks improve handling on lifted 2500\/3500 HD trucks?\u003c\/h3\u003e\n\u003cp\u003eThe N3 valving is tuned to compensate for lift kits up to 3 inches, delivering firmer control through compression and rebound cycles.
