“Death wobble” manifests as the steering wheel violently moving back and forth under your hands. Vehicles that utilize a track bar with solid front axle are more likely to develop a death wobble. To eliminate the effect, you need to determine which parts of your vehicle’s suspension are causing the issue. Despite its frightening name, […]

(Leave shock pressurized to begin, as it will assist with removing wipercap) Clean shock, and put into soft jawed vice or something to hold it upside-down. Loosen wiper cap with a spanner wrench/channel-lock pliers. Unscrew and slide wiper cap assembly up shock shaft. De-pressurize shock completely. Push sealhead assembly downward into shock to expose snap […]

F-O-A starts out with the longest Teflon shaft bushing in the industry, at a full 1 inch long, it is 33 percent longer giving you more shaft support. F-O-A continues with a double OD O-ring seal. Over time and with use, a single O-ring design can leak. With constant pressure variations causing O-ring flexing, the […]
Off-Road Shock Tuning Guide Without getting too advanced, shock tuning is about selecting the right combination of compression and rebound shims and stacking them in the proper order to get the shock damping characteristics you are after. While shock tuning is as much of an art as it is a science which takes a lifetime […]
How Shocks and Shock Valving Works Shock absorbers dampen the suspension movement of a vehicle to improve handling and performance by forcing specially formulated shock oil through tightly controlled holes (ports) in the shock piston to convert kinetic energy (movement) into thermal energy (heat). Most high performance shocks are similar in design and feature a […]
