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!
