Doetsch Systems' HV1 Remote Reservoir Shocks
Doetsch Enterprises has been a leader in the manufacturing of performance shock absorbers (dampers) for about 22 years. The company's quest for the ultimate in shock absorbers is continually refined using the latest technology and hands-on race and four-wheeling experience. Doetsch has personally developed and raced each shock system it sells.
The HV1 performance shock was originally designed for testing and ride evaluation purposes only, but due to its high demand and reputation, the dampers are now available to the public. These high-performance shocks come with or without remote reservoirs. We chose the HV1s with the remote reservoir for our 300,000-mile Toyota because of the many different types of terrain the rig is driven on. The shock may run a bit cooler with the addition of the reservoir because it holds more of Doetsch's high-temperature compensating fluid, but the reservoir mainly reduces hydraulic lock, offering a smoother, more consistent dampening effect as the fluid moves in and out of the reservoir.
The shocks are built with rugged 46mm-bore housings and then coupled with chrome-plated piston rods for dependability and strength. Each shock is built in-house with the disk valving tuned exactly for the specific needs of each customer. Each shock is filled with the right amount of the finest high-temperature compensating fluid and uses high-pressure nitrogen gas with free-floating valve technology. The HV1s are completely rebuildable.
Before Doetsch built the shocks for our 300,000-mile Toyota, it specifically asked what types of terrain we would be driving over. The 4x4 is used almost weekly on an adventure basis, so we needed a universal type application; one week we may be running the Hammer Trails in Johnson Valley, the next week exploring the High Sierras, and the week after that blazing across Death Valley. As soon as the new performance HV1s were bolted to the truck, we could immediately notice the difference between the custom-built dampers and the mass-produced factory shocks we replaced. The HV1s are extremely forgiving and comfortable out on the trail, especially while absorbing the blunt trauma of a trail hazard. The dampers' on-highway performance are exceptionally surprising, especially because we are running very large and very heavy tires with an aggressive mud-terrain-type tread pattern.
