QA1 63 Series Sealed Threaded Body Twin Tube Shock Absorber - 9in Stroke - 4-4 Valving - Aluminum

The 63 Series is a sealed non-rebuildable version of the 62 Series. These are most commonly used in coil-over applications on both dirt and asphalt tracks. The twin tube design gives excellent feel and grip across all track conditions, but they really shine when there is a lack of grip. Built as a spec shock that could be used at specific tracks or series, the 63 Series can be used in any late model or modified.
