Going fast off-road has always involved a trade-off between control and comfort. In stock form, most trucks drive down the highway very smoothly, but mash the loud pedal through the whoops and you'll realize how horrible they handle when the speeds increase. Once you upgrade your suspension to deliver a decent amount of travel, you can really start pushing the limits of your truck.
Reservoir shocks are perfect for smoothing out the ride over harsh terrain, but if you want more control at higher speeds, you often lose ride comfort at lower speeds. Well, thanks to Bilstein, you can now have it all.
Bilstein has bridged the gap between control and comfort with its new revolutionary 60mm ACV (Anti Cavitation Valve). The ACV restricts the flow of the oil in the reservoir at higher speeds giving you a stiffer valving that is ideal at higher speeds when you need to keep the front end elevated. This allows the valving in the main piston to be lighter, increasing overall smoothness and comfort at lower speeds while still delivering precision control at higher speeds. Because the ACV is velocity sensitive, the harder and faster you hit, the more it restricts flow, eliminating any possibility of oil cavitation.
The ACV is made out of 7075 aluminum and has a heat sink integrated into its design to help dissipate heat in the shock. Best of all, it can be added on to all Bilstein shocks from the 7100 series and up.
