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. At first glance the reservoir looks slightly different than what we're accustomed to seeing. That's because the ACV has a heat sink built into its design to help prevent oil from thinning out due to heat build up.At first glance the reservoir looks slightly different than what we're accustomed to seein Here you can see why the ACV can make any coilover or reservoir shock more effective. The oil is forced through channels in the ACV before it reaches the inside of the reservoir. This allows the shock to remain stiff over high speed bumps without the use of a stiff main stack valving. The ACV is velocity sensitive, so it only kicks in at high speeds and hard hits - unlike conventional internal bypass shocks, which are position sensitive.Here you can see why the ACV can make any coilover or reservoir shock more effective. The The ACV creates a pressure surge in the shock when you encounter a large bump at high speed. It can almost double the pressure inside the shock so you don't blow through the travel. This is similar to an internal bypass shock except that it can go to a stiffer zone at high speeds without having to go through another zone first.The ACV creates a pressure surge in the shock when you encounter a large bump at high spee The ACV is perfect for applications in which both low-speed comfort and high-speed control are necessary. It may be too aggressive for the rear, because you normally want a softer ride in the rear. The ACV is excellent for Class 11 buggies where you need a stiffer rear, but other than that Bilstein recommends them for use on the front only.The ACV is perfect for applications in which both low-speed comfort and high-speed control Just in case you're wondering how the ACV performs, we have a set of Bilstein's coilover shocks with the new ACV system that are just waiting to go on one of our project trucks. We're definitely looking forward to seeing how they perform at high speeds.
