51 Series Twin Tube Steel Shock

The best keep getting better! Weve taken your feedback, added new technology and developed an improved 50 Series shock absorber the 51 Series. QA1s 51 Series features a brand new in-house machined body, which has a large inside diameter for easy installation of gas bags. This twin tube shock absorber features hard anodized internals and has a zero gas pressure design providing the most grip on slick tracks and the best feel of any shock. Available in seven and nine inch strokes, the 51 Series is the premium twin tube choice for dirt and asphalt modifieds, late models and super stocks. The 51 Series is manufactured in QA1s Lakeville, MN facility and is completely racer rebuildable and revalveable.

Additional Piston Option: QA1 also offers a brand new high-flow linear two port piston for the 51 Series as an additional accessory. This two port piston design allows the valve discs to open consistently which results in a smoother force curve and accommodates independent compression and rebound bleed circuits for precision low-speed force control.

Note: Be sure to check compressed and extended lengths carefully for proper fit. QA1 lengths do not necessarily correspond to competitors lengths.

QA1 also offers these shocks in packages specific to a variety of series. Contact QA1 for more information.
