QA1 Precision Products 8Q45 Twin Tube Racing Shock Absorber 4-Inch Stroke

The QA1 8Q45 is a high-performance rebuildable twin-tube shock absorber engineered for racing applications demanding precision, consistency, and tunability. Part of QA1's 8Q Series (formerly known as the 82 Series), this aluminum small-body shock features a 4-inch stroke and comes pre-valved with 5C/5R (5 compression/5 rebound) settings to deliver balanced damping control right out of the box.

Key Features:

• Aluminum small-body design with threaded body for easy coil-over configurations
• Rebuildable twin-tube construction for long-term serviceability and tuning flexibility
• Bearing mount configuration with scalloped base loop for improved clearance in tight areas
• High-quality raw aluminum pistons for maximum consistency and performance
• Compact outside diameter ideal for lightweight racing classes and clearance-restricted applications
• Approximately 15.75 inches extended length with eyelet mounts
• Fully tunable - can be revalved with bleed shims or drilled bleeds to customize damping characteristics

The QA1 8Q Series delivers all the performance of QA1's proven large-body shocks in a more compact, space-saving package. Designed specifically for circle track racing, drag racing, and other motorsports applications where rules or physical constraints require a smaller shock footprint, the 8Q45 combines professional-grade performance with the versatility racers need to dial in their suspension setup.
