located on the CabRac base one inch from the end, as shown, tighten
using a5/16" Allen Wrench. Reference Figure10. Torque to 270 in/lbs.
4. Repeat for opposite side.
5. Go through all bolted connections and ensure that they all are fully
secured and tightened to the recommended torque.
Notes:
For good performance and safety, we recommend re-torquing all clamps and fasteners to the proper specifications after
the first 500 miles and every 5000 miles thereafter.
Carrying high loads over rough roads with excess speed may damage the system on your truck. Exercise good judgment
at all times.
