Bilstein Shocks for Circle Track & Road Racing
Why Race On Bilstein Shock Absorbers?
  1. Because the valvings are consistent, your set-ups will be more precise.
  2. Bilstein’s larger piston and deflective disc valving develop control force when you need it, at the slightest movement of the suspension. You’ll get weight transfer when you need it, better control under braking and your tires will stay on the track through the rough spots.
  3. Bilstein shocks don’t fade. Your chassis will handle as good at the end of the race as it did at the start.
  4. Bilstein shocks are rugged. They last for years and are rebuildable and revalvable.
  5. When the advantages of Bilstein gas pressure shocks are tallied up, you will have spent less money on shock absorbers and collected more money at the pay window.

Why is the shaft on a Bilstein shock always extended?

As monotube gas shocks, Bilstein shocks are under gas pressure to deliver the most responsive valving for ultimate control. This pressure, called the gas reactive force, and Bilstein’s perfect internal seals force the shaft to be extended.

Is the car more difficult to scale with Bilstein shocks?

Bilstein shocks have no effect on the results as you weigh the four corners. The gas reactive force in Bilstein shocks may raise your car’s ride height slightly. Simply adjust the chassis downward to the desired ride height.

Does Bilstein offer specific applications for the various dirt and asphalt racing series?

As the set-up charts in this catalog indicate, Bilstein has shocks specifically valved for both dirt and asphalt surfaces of various track lengths.

Are Bilstein shocks difficult to understand and use?

After reviewing the various set-ups in this catalog, you’ll be ready to select the proper shocks for your specific race car. Bilstein valving is precise. Once you purchase your Bilstein shocks, you can be certain they will perform at peak efficiency throughout their long life.

I can buy twin-tube shocks for less money than Bilstein shocks. Why should I spend the extra money?

As we point out in this catalog, Bilstein shocks are fabricated from the highest quality components for long life performance. Typically, Bilstein shocks are only slightly more expensive than twin-tube brands. Since they will far outlast conventional shocks, Bilstein shocks cost much less over the long run. Bilstein shocks are the least expensive way to lower your lap times.

The companies that sell only twin-tube (low pressure gas) shocks say their design out performs monotube (high pressure gas) shocks. How can I know the truth?

Take a trip to a local discount department store that sells replacement shocks for cars and trucks that drive on the street. You’ll find shocks priced from about $8.99 to $29.99. All of the shocks on display will be twin-tube shocks. Their price reflects the fact that twintube technology is relatively unsophisticated and very low cost to produce. At a new car dealership you’ll find that low cost base line cars and trucks are factory equipped with twin-tube shocks that add very little to the cost of the vehicle. Factory installed Bilstein shocks can also be found on Mercedes-Benz, Ferrari, Porsche, Toyota TRD, Roush and many other high performance vehicles around the world. Finally, take a stroll through the pit area at a NASCAR Cup, Busch, Craftsman Truck, CART, IRL or Formula One race and you’ll find not a twin-tube shock in sight! The top racing engineers in the world always use monotube gas shocks! By searching out the facts, you will know the truth...and the truth will make you faster!
