Frequently Asked Questions

How do I know if I need the left hand or right hand torsion arm?

Stand facing your RV awning from outside. If the arm you need to replace is on your left side, order the left hand version. If it's on your right side, order the right hand version. Ordering the wrong orientation will not fit your awning.

Can I install this torsion arm assembly myself?

Yes, this is a direct replacement part. However, torsion arms are under spring tension and can be dangerous if mishandled. We recommend having a qualified RV technician perform the installation to ensure proper alignment and safe operation. Improper installation can result in awning malfunction or injury.

What symptoms indicate my torsion arm needs replacement?

Common signs include difficulty extending or retracting the awning, the awning not staying fully extended, visible bending or damage to the arm, or grinding/squeaking sounds during operation. If you notice any of these issues, replacement is typically necessary to restore safe awning function.
