The best keep getting better! We've taken your feedback, added new technology and developed an improved 50 Series shock absorber - the 51 Series. QA1’s 51 Series features a brand new in-house machined body, which has a large inside diameter for easy installation of gas bags. The 51 Series is the premium twin tube choice for dirt and asphalt modifieds, late models and super stocks.

• Available in seven and nine inch strokes
• Racer revalveable & rebuildable
• Twin Tube Shock Absorber features hard anodized internals
• Steel Large Body style
• Zero gas pressure design provides great grip on slick tracks and an outstanding feel
• Premium Aluminum piston - dual bleed circuits for standard or custom valvings
• Premium proprietary blend of specially engineered oil prevents fading
• 15mm centerless ground, hard chrome plated, solid piston rod
• Deflective disk valving allows control of suspension at low shaft speeds without creating extreme forces at high shaft velocities
• Can run upside down with no rate change to reduce unsprung weight
• Replaceable 1/2" I.D. bearings
• 100% Dyno tested & serialized

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.
