Shock N2 Upgrade W/#700 Spring

Nitrogen-charged shock upgrade for the Rush SR with 700 lb/in spring rate. The N2 (nitrogen gas) charging provides more consistent damping performance throughout the shock stroke and reduces cavitation compared to standard oil-filled shocks. This upgrade offers better suspension control for aggressive driving and higher-grip tire compounds.

The Rush SR standard suspension uses two-way adjustable coilover shocks. This N2 upgrade takes that platform further with nitrogen gas pressurization that maintains damping consistency as the shock heats up during track sessions. The 700 lb/in spring rate provides a moderate increase in stiffness over the baseline setup, suitable for drivers seeking improved suspension response without the added stiffness of the 800 lb/in spring option.

Sold individually—the Rush SR uses four shocks (front left/right, rear left/right). Two-way adjustable for compression and rebound damping. Includes spring perch adjusters for ride height tuning. See the Rush SR Manual section on shock adjustments for tuning guidance.
