For vehicles that need a little extra fluid capacity in their steering systems, these reservoir extensions are a simple thread-on solution.
Available in heights of 3" or 6", they install between the reservoir body and cap to provide additional volume for fill level rise that can be caused by fluid thermal expansion or shaft displacement of single ended steering cylinders and active air shock setups used in some competitive rock crawlers.
These fit all Radial Dynamics Gen II Vortex Steering Reservoirs as well as latest generation reservoirs from PSC Motorsports. Reservoir and/or cap sold separately.
