    Electroless Nickel Plated Body
    Based on the rock solid 26 Series platform, the 28 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 28 Series also features an expanded gas chamber. This expanded gas chamber eliminates the unwanted rod force increase when the shock is compressed.

    Hi-Lo Piston
    The newly designed Hi-Lo Piston is designed to be user friendly and extremely versatile, featuring kidney shaped ports on one face and round ports on the other. This feature allows the piston to be flipped to create a softer curve on one side coupled with a stiffer curve on the other side. This versatility allows the Hi-Lo piston to be used in any position on the car. The hard anodized finish creates a wear resistant surface and reduces valve friction for more consistent performance. The piston features substantial porting to increase flow characteristics and can be retrofitted to QA1 26 Series shocks, too.

    Sealed Hyperscrew (28A Series)
    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 (IMCA) and track rules.
