QA1 GD401-10350C Pro-Coil Front Coilover Kit GM For Sale

Upgrade the front suspension of compatible GM applications with the QA1 GD401-10350C Pro-Coil Coil-Over Shock Kit. Designed for performance-focused street, autocross, road racing, and other driving applications, this matched pair combines QA1 twin-tube shocks with adjustable coilover components and 350 lb/in springs. Verify vehicle compatibility and suspension requirements before purchase, as fitment varies by GM application.
The double-adjustable shock design provides separate control over compression and rebound settings, allowing suspension tuning for handling balance, ride quality, and changing track or road conditions. The Pro-Coil system is intended for users who want greater control than a conventional fixed shock and spring combination while maintaining a serviceable, tunable front suspension setup.
This kit includes a pair of front coil-over shocks with 350 lb/in springs for the specified applications. QA1 and Pro-Coil branding are referenced for product identification and fitment verification. Installation should be completed by a qualified technician using the appropriate vehicle-specific hardware, alignment procedures, and manufacturer-recommended settings. Always confirm chassis compatibility, available suspension travel, ride-height requirements, and spring selection before installation.
