We stock torsion springs in the sizes that match 1980s and 90s residential doors, since that's most of what we're repairing out here - standard wind counts, standard wire gauges, not the oddball sizes you'd need for a much older or much newer build. Cable, rollers, and the common extension spring sizes ride along too, along with the hardware for track realignment, which handles a fair share of the cold-weather calls.
What we don't carry on every truck is opener logic boards or less common gear-drive assemblies for openers that have been swapped out over the years - if your opener's been replaced once or twice already and isn't a stock unit, that part sometimes has to be ordered. We'll tell you straight if that's the case rather than have you wait on a truck that isn't bringing the right board. For doors and hardware original to the house, though, the truck's built around exactly what West Pasco has.
