Garage Door Cable Drum Replacement Austin, TX
The drums are what wind your cables and lift the door evenly. A cracked or worn drum makes the door hang crooked and jump the cable — we replace them in matched pairs.

Cable drums are the grooved wheels at each end of the torsion shaft that the lift cables wrap around as the door opens. They do the quiet, critical work of raising both sides of the door evenly — and when a drum cracks, wears, or the setscrews slip, the door starts hanging crooked, one cable goes slack, and the whole system binds. On heavy or tall doors, the wrong-size drum can also let cables slip off entirely, dropping the door or leaving it jammed at an angle. Shockwave replaces cable drums on residential and commercial doors across Austin, always in matched pairs so both sides wind at the same rate. Because the drums sit inside the tensioned spring system, replacing them means safely unwinding the springs, resetting the cables, and re-tensioning to spec — not a DIY job. While we're in there, we inspect the cables, bearings, and springs so you don't get a repeat visit for a related part.
Signs Your Cable Drums Need Replacing
How We Replace Cable Drums
We safely release all spring tension before touching the drums, then remove both worn drums and install a correctly matched pair sized to your door's height and lift type. We rewind and set the cables to equal tension, secure the setscrews properly, re-tension the springs, and balance the door so both sides lift together. We always replace drums in pairs — installing one new drum against an old, worn one just leads to uneven lift and another service call. Cables and bearings get inspected in the same visit.
Frequently Asked Questions
How much does cable drum replacement cost in Austin?
Replacing both cable drums typically runs $180–$350 depending on door size and whether cables or bearings need replacing at the same time. We quote a firm price after inspecting the system.
Why replace both drums if only one is bad?
Drums must wind at the same rate to lift the door evenly. Pairing a new drum with a worn one causes uneven tension and crooked travel, so we always replace them as a matched pair for reliable operation.
Can I replace a cable drum myself?
We don't recommend it. The drums sit inside the tensioned spring system, and unwinding those springs without proper tools is how serious injuries happen. This is a job for a trained technician.
What causes a garage door drum to fail?
Age and metal fatigue, impact damage, overloading a heavy door with undersized drums, or a loose setscrew that lets the drum spin on the shaft. Cracked grooves then fray the cable and throw off the door's balance.
Do you service high-lift and commercial drums?
Yes. We stock and install standard, high-lift, and commercial drum types, sizing them correctly to your door's height and lift configuration so cables wind properly and the door lifts evenly.
