Frequently Asked Questions
Q: How do I know if my torsion arm needs replacement?
A: Signs include awning that won't extend fully, uneven deployment, grinding noises during operation, or visible cracks in the arm. If one side extends faster than the other, the torsion arm is likely worn.
Q: Do I need to replace both left and right torsion arms?
A: While you can replace just one side, Dometic recommends replacing both arms together for balanced performance and even awning operation. Order the right-side assembly separately if needed.
Q: Will this fit my Dometic awning model?
A: This assembly is designed for Dometic 8500 and 9000 series awnings. Verify your model number on the awning bracket before ordering to ensure compatibility.
