NOTE: A 4-point subframe is advantageous for additional support point loading, and is required for sub-frame length greater than 14'.

NOTE: A 3 / 4-point subframe is available for larger subframes (14' and greater) that need a four point subframe for additional pin pointed loading requirements, but also want to pass through. This subframe allows the habitat to track more closely to the cab of the truck and helps to prevent the pass through boot from dislodging. Add the Heim Joint Kit below for total pricing.
