The 28A Series shocks feature a sealed hyperscrew. The gas pressure of these shocks is only adjustable by QA1 and QA1 Authorized Rebuilders per sanctioning body, like IMCA, and track rules.
Electroless Nickel Plated Body
The 28A Series is electroless nickel plated on the inside and out, encapsulating the base metal to completely seal out the elements and creating a durable, smooth finish on the inside for a consistent performance. This nickel plating provides excellent corrosion resistance, superior hardness, consistency and lubricity.
Expanded Gas Chamber
The 28A Series also features an expanded gas chamber. This expanded gas chamber eliminates the unwanted rod force increase when the shock is compressed.
Linear, Digressive and Low Speed Super
Digressive Valving Available
Digressive is the classic monotube shock feel. Linear provides a more stable car and allows the driver to feel the car better. Low Speed Super Digressive is an excellent choice when maximum rebound force is needed for big, low speed, tie-down applications

In this episode, Project Chevelle gets coilovers and a much-needed altitude adjustment. Watch as we install QA1 bolt-on coilover kits front and rear, then dial in the perfect stance and shock settings. Our old Chevelle is really starting to look mean!
