XR1 Single Way Adjustable Coilover Kit

The Stance XR1 coilovers are engineered as a daily-driveable suspension upgrade for the 2003-2009 Nissan 350Z (Z33), designed to handle commuting, spirited driving, and occasional track days. Each kit is dyno-tested to ensure performance and shipped ready for installation with pre-tuned spring rates and fully adjustable damping. Key features include 16 levels of single-way damping adjustment for precise tuning, an inverted monotube front damper with a 45mm shaft for increased rigidity, and digressive valving for optimal chassis control and bump absorption. The coilovers utilize pillowball front top mounts for direct steering feel and are constructed with heat-treated chromoly piston rods and T6061 aluminum brackets. A two-stage zinc and electrodeposited coating provides over 1,000 hours of salt-spray resistance. These coilovers are 100% rebuildable and revalvable at the Stance Suspension facility in Texas, allowing them to adapt to evolving driving needs. The rear assembly retains the OEM spring location with an included adjustable spring perch for ride-height adjustment. Swift Springs are available as an upgrade. Important fitment notes indicate that all suspension products, including this kit, are designed for 2WD vehicles only. Aftermarket coilovers are generally not compatible with OEM electronic damping control systems unless explicitly stated. The product images provided may not precisely represent the actual SKU.
