We have just added the new Pro Comp Pro Runner Shock series to our site. They are Monotubes, and are a great upgrade to a stock or slightly lifted FJ. They feature vehicle specific ride tuning and have a Lifetime warranty.
Pro Runner™ monotube shocks are specifically designed for late model trucks, Jeeps® and SUV's. At its heart is a gas-charged monotube design that delivers superior performance compared to traditional twin tube shocks. The nitrogen gas pressurized body eliminates performance-robbing cavitation during compression and rebound, allowing efficient heat dissipation. The Vehicle Specific Ride Tuning (VSRT™) in each shock was produced using extensive dyno and real world testing. The result is multi-stage valving to optimize the ride and handling characteristics for each application.
