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

Great Cabin Filter Upgrade
Style: BE-729H 1-Pack, Style: BE-729H 1-Pack
I recently replaced my old cabin air filter with this one, and the difference was noticeable right away. Installation was quick and straightforward took less than 10 minutes with no special tools needed. What I appreciate most is the air quality improvement. The airflow feels stronger, and there’s a clear reduction in dust, odors, and outside pollution entering the cabin. If you’re looking for an easy, affordable upgrade that actually makes a difference in everyday driving comfort, this cabin filter is definitely worth it.

Excellent Air filter - Easy installation.
Style: BE-743 1-Pack
Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.

Great filter and easy installation
Style: BE-159 1-Pack, Style: BE-159 1-Pack
For my 2016 Hyundai Sonata Hybrid Limited. I cannot believe I paid so much more for a brand-name filter that does the same thing as this one. It is made of the same material as the dealer one I took out. Very easy to install, cant believe I paid for this to be done in the past with oil changes. Requires no tools and did not get dirty at all. No mechanical skills needed, especially if you run into trouble and can use YouTube. PROS - great quality, cannot tell that it is after-market - very professionally made, not irregularities seen - excellent fit in position, no adjustment needed - very easy to install, cannot believe I paid to have this done in the past - no mechanical skills needed to install - great price compared to what big name productions want for the same thing - cannot tell the difference in air quality between this and the dealer filter I took out - removes outside odor completely - did not require tools are getting dirty CONS - None

Fits perfect and works as designed. Flows like OEM and looks well made.
Style: BE-553B 1-Pack
This filter is very comparable to the stock filter. Fits the BMW G20 just like OEM. I would not say it is two times "heavier" as advertised on the box, but it is very comparable to stock. It's the same weight and similar construction. BMW has a very robust cabin filter. This will be my go to. I did purchase another aftermarket cabin filter that fit well, but was thin, flimsy and had a bad chemical odor. This one is fine and airflow is the same as OEM. I change them every year or so. I don't worry too much about longevity with cabin filters personally.

Good quality but it was slightly longer than original and needed modification.
Style: BE-182 1-Pack
Bought this cabin filter for a 2023 Acura TLX. While the filter seems to be made of quality material, it was just a little too long (about a 1/16 of an inch, so I had to trim it to make it fit so the cover would fit snug. I was able to do that without compromising the filter itself. But this might be an issue for some people
