The 26 Series shock is a one piece monotube shock that is well suited for a variety of track conditions or as a traction shock in various applications. Constructed with a zinc plated body for corrosion resistance, this shock is a popular choice for modifieds, late models, super stocks and various other classes. Works best on rough tracks and as an easy-up shock on many dirt cars, and on bumpy asphalt tracks in all banking types. Made with a 2'' O.D. zinc plated steel monotube body and available with hyperscrew, sealed Hyperscrew (IMCA Legal) or Schrader valve configurations, the 26 Series shocks use deflective disc valving with either linear, digressive or linear/digressive valving. The hyperscrew equipped shocks have a threaded round port near the bearing end of the shock body. This hole is then sealed with a small screw that has an O-ring built into it, sealing the nitrogen gas pressure inside the shock. The gas pressure of the sealed hyperscrew configurations is only adjustable by QA1 and QA1 Authorized Rebuilders per sanctioning body, like IMCA, and track rules. With a Schrader valve you can easily adjust your gas pressure. Much like adding air to your car tires, the Schrader valve allows you to make ''on the fly'' gas pressure adjustments between heat races and features to adjust for varying track conditions. The 46 MM piston allows for maximum car control at all shaft velocities. They are racer rebuildable and revalveable for unparalleled repeatability. Made in the USA and 100% dyno tested and serialized.

  • Every QA1 shock is dyno-tested and serialized to guarantee peak performance
  • Multiple valving curve and gas charging options
  • Racer rebuildable and revalveable
  • Made in the USA

Vast improvement in substance and organization; a few downsides
Format: Spiral-bound, Format: Spiral-bound
Among my other writing-related pursuits, I edit PhDs. This APA 7 manual is a big improvement over earlier APA editions. The primary purpose of any edition is to update the APA standards. This manual is packed with content and examples that were IMO long overdue. For instance, there are templates to show the order of data for Reference entries, and there are side-by-side examples of Reference and in-text citations. I ordered the wire-bound version because it works well in any workspace (i.e., you can easily fold the book in half or leave it wide open. The chapters are divided by tabs, with the ToC (table of contents) for that chapter printed on the tab. Compared to earlier versions, the font is smaller, but it remains highly readable. The margins are wide enough for notes. There are several downsides to the manual that I hope will be resolved in the next edition: (a) For such a large manual, the cover on the wirebound copy is both too short and relatively flimsy. It is too short because it is only the width of the pages. It does not extend over the tabs. It is too flimsy because it is the same weight as earlier and less substantial manuals. (b) There is no tab for the index. (c) Although the font in the chapters is a sufficient size, the font in the index is much smaller and the index pages are crowded; there is less room in the margins for taking notes. I dealt with the cover-related problems by cutting up a transparent binder/page sleeve for the front, back, and spine of the cover, and by creating my own tab for the index. There's nothing to be done for the index font except to live with it. You can get the gist of what I've reported here by looking at the pictures I've attached.
