QA1 TD803 Stocker Star Double Adjustable Shock Absorber

The QA1 Precision Products TD803 Stocker Star shock absorber delivers professional-grade suspension tuning with dual adjustment capabilities. Designed for drag racing and street/strip applications, this shock features independent compression and rebound adjustment knobs that provide 18 clicks each, creating 324 distinct valving combinations to fine-tune your suspension for optimal weight transfer and traction.

Key Features:

• Double adjustable design with independent compression and rebound control
• 324 valving combinations (18 clicks compression x 18 clicks rebound)
• High-pressure monotube construction for consistent performance and fade resistance
• Precision-machined aluminum body with hard-anodized finish
• Large 1.375-inch bore diameter for increased oil capacity and cooling
• Serviceable and rebuildable design for long-term value
• Application-specific valving optimized for drag racing weight transfer

The Stocker Star series is engineered for racers who demand precise suspension control. The dual adjustment knobs allow you to dial in the perfect balance between compression damping (controlling how the shock compresses under load) and rebound damping (controlling how quickly the shock extends). This level of adjustability enables you to optimize launch characteristics, control weight transfer, and maintain traction across varying track conditions.

QA1's monotube design ensures consistent damping performance by eliminating aeration and maintaining stable oil temperatures even during repeated hard launches. The serviceable construction means these shocks can be rebuilt and revalved as your setup evolves, making them a long-term investment in your vehicle's performance.
