Frequently Asked Questions

Q: How do I know if my torsion assembly needs replacement?
A: Signs include uneven awning extension, difficulty retracting, sagging on one side, or the awning feeling heavier than normal. A worn torsion bar loses tension over time and can strain your awning motor.

Q: Will this fit my Dometic SlideTopper awning?
A: This 43-inch left-hand assembly fits most standard Dometic SlideTopper models. Verify your awning model and confirm the left-hand orientation before ordering. Contact our support team if you're unsure about compatibility.

Q: Is professional installation required?
A: Torsion assembly replacement involves spring tension and requires mechanical knowledge. We recommend professional installation to ensure proper tensioning and safe operation. Improper installation can damage the awning or cause injury.
