QA1 R356-170S Single-Adjustable Coilover Suspension Conversion System 170 lb/in

The QA1 R356-170S is a single-adjustable coilover suspension conversion system engineered for enthusiasts seeking improved handling, ride height adjustability, and performance over factory suspension setups. QA1 Precision Products designs this system to replace stock suspension components with a fully integrated coilover solution, allowing precise corner-weight tuning and ride height adjustment without compromising ride quality.

Key Features:

• Single-adjustable damping — easily dial in compression and rebound with a single adjustment knob for simplified tuning
• 170 lb/in spring rate — matched spring rate provides a balance of performance handling and street drivability
• Ride height adjustability — threaded shock body allows fine-tuned ride height settings for aggressive stance or improved cornering geometry
• High-strength aluminum construction — lightweight components reduce unsprung weight for improved suspension response
• Rebuildable and serviceable design — QA1 coilovers are fully rebuildable, extending service life and reducing long-term ownership costs
• Precision-machined components — manufactured to tight tolerances for consistent, repeatable performance

QA1 Precision Products has been a trusted name in performance suspension for decades, supplying components to drag racers, road racers, and performance street drivers alike. The R356-170S conversion system is a direct upgrade path from worn or inadequate OEM suspension, delivering the adjustability and performance expected from a purpose-built coilover system.
