Install Stabilizer Foot
Attach one Stabilizer Foot (K) to the Left (E), Right (F) and Center
Support (AB) Brackets by threading one Flange Nut - 5/16” (P)
onto Stabilizer Foot (K) shaft and insert through the lower hole of
each Bracket (E,F and AB). Thread a second Flange Nut (P) onto
Stabilizer Foot (K) shaft sandwiching the Bracket in between.

Extended Stabilizer Foot
Some installations require a longer Stabilizer Foot (K) (Toyota
Tundra for example). In such cases, prior to installing the
Stabilizer Foot (K), attach one Hex bolt - 5/16” x 2” (U) and
Coupling Nut - 5/16” (X) to each Stabilizer Foot (K).
