Bonbo RV Torsion Arm Assembly, Right-Hand — Fits Dometic A&E 8000/8500/9000; OEM-fit spring & travel latch

If your RV or camper awning struggles to roll in, rolls unevenly, or won’t stay secured while driving, swapping in a matching right-hand torsion spring assembly is often the fastest and most cost-effective fix. This Bonbo assembly is built to meet OEM fit and function for popular Dometic A&E and Sunchaser II models, giving your existing roller tube the correct spring tension, cam action and travel latch so the fabric rolls up cleanly and remains locked during transit.

How does this part get my awning rolling like new again?

The torsion arm replacement includes the wound coil spring and right-end cam assembly that together apply the correct torque to the roller tube and prevent rollback. When installed, the spring tension assists winding the fabric while the cam and latch hold the roller in the travel position, eliminating sagging and unwanted unrolling.

• Complete right-hand end assembly with spring and top casting
• Cam prevents billowing and rollback during travel
• Restores original tension for even, smooth rolling
