How to Spec

Each FlowBelow Tractor AeroKit and Wheel Cover Kit is assembled to match the specifications of your truck or trailer.  It is important that we gather and understand your vehicle’s specs to ensure we ship the correctly configured products. 

To spec Trailer Wheel Covers, contact us or give us a call at 512-524-4510.

NOTE: If you have multiple identical trucks, you can update the 'truck quantity' field to the appropriate quantity. Otherwise, each unique truck will require a separate spec submission.
