QA1 6Q64-650R Rebound Adjustable Twin Tube Circle Track Shock 6" Stroke Large Body Aluminum Coil-Over

The QA1 6Q Series is a large-body aluminum shock formerly known as the 60 and 62 series, specifically engineered for circle track racing and high-performance coil-over applications. This 6Q64-650R model features a 6-inch stroke with rebound adjustable valving (650R specification), allowing racers to dial in their suspension settings at the track for optimal performance.

Key Features:

• Threaded body design for easy integration with QA1 coil-over kits
• Rebound adjustability to easily fine-tune valving at the track
• High-quality raw aluminum pistons to maximize consistency
• Scalloped base loop increases clearances in tight areas like upper control arms and shock mounts
• Racer rebuildable and re-valveable in minutes using basic tools and available kits
• Twin tube design provides excellent feel and grip across all track conditions
• Large body construction for increased oil capacity and heat dissipation

These shocks are commonly used in coil-over applications on both dirt and asphalt tracks and can be used in any late model or modified racing applications. The 6Q64-650R delivers professional-level performance with the tunability and rebuildability that serious circle track racers demand.
