QA1 just announced the latest addition to its ever-popular and expanding circle track line of products--the 28 Series gas-pressurized shock. The 28 Series gas-pressurized shock includes an expanded gas chamber. This chamber eliminates unwanted rod force increase when the shock is compressed. The 28 Series also includes the tried and true features of the 26 Series, including the electroless nickel-plated body for excellent corrosion resistance, superior hardness, consistency, and lubricity and the 15mm centerless ground, hard chrome-plated piston rod that eliminates piston rod flex, increasing valving consistency.
The 28 Series also features QA1's new Hi-Lo piston. This piston is designed to be user friendly and extremely versatile with substantial porting to increase flow characteristics. It features kidney-shaped ports on one face and round ports on the other, allowing the piston to be flipped to create a softer curve on one side coupled with a stiffer curve on the other, allowing it to be used in any position on the car. With a hard coat anodized finish on the Hi-Lo piston, valve friction is reduced for more consistent performance. The Hi-Lo piston can be retrofitted to QA1 26 Series shocks also.
