INSTALLTION OF RACK
STEP 9: Measure the length of the top rail on your truck bed with the tailgate closed.
Subtract 3 ½” from this measurement, this gives you the approximate spacing needed between the
front and rear uprights.
Adjust your front uprights by sliding them forward or backwards to match this measurement.
(Fig O, P) Once position is correct tighten bolts snug, but not completely.
(Fig O) (Fig P)
STEP 10: Place the adjustable cross bar (#11) in the desired location. This bar can always be moved around
depending on the size and weight of your load. (Fig Q,R,S)
Attach using two M12x75 bolt sets. You may tighten completely at this time.
