Craftsman Torsion Spring Replacement: The Tarzana Owner’s Guide
We stock and install Craftsman-compatible torsion springs in Tarzana, with most replacements running between $180 and $340 installed, depending on the spring size and cycle rating on your door. If your Craftsman door is sitting dead on the tracks, the spring is almost always the culprit, and we can usually have it turning again the same day you call. The story we hear most from Tarzana homeowners goes like this: the door worked fine last night, and this morning it made a sound like a rifle shot, the cable went slack, and nothing would budge. That’s a torsion spring letting go, and it’s the single most common failure on any Craftsman door in the San Fernando Valley.

Which Craftsman Models This Applies To
Craftsman has put its name on a lot of door hardware over the years, so here’s the straight answer on compatibility. The torsion spring itself doesn’t care what badge is on the door. What matters is the spring’s inside diameter, wire gauge, length, and the wind direction, left or right. Every Craftsman door we service in Tarzana, from the older 1/2 HP chain-drive era doors to the newer belt-drive models paired with Craftsman openers, runs on a torsion assembly sized to the door’s total weight. You’ll find the spring specs printed on a tag near the spring pad, or painted on the end cone of the spring itself. And if the tag’s gone, we measure the old spring before we quote a replacement. One thing to know: Craftsman discontinued its own door line years ago, so there’s no such thing as a genuine Craftsman spring anymore. What you get from us is an OEM-equivalent from manufacturers like SSC or Raynor-grade stock, cycled to match or beat your original. The aftermarket springs we install in Tarzana are every bit as good as, and often rated for more cycles than, the spring that came with the house.
Signs Your Craftsman Torsion Spring Replacement Is Failing
- The door feels heavy when you pull the manual release. A healthy spring carries most of the door’s weight. When it’s losing tension or has broken, you’re lifting 150 to 200 pounds by hand. If the door suddenly feels like dead weight, the spring has already failed or is about to.
- You can see a visible gap in the spring coil. Torsion springs snap clean in two. Walk out to the garage and look up at the shaft above the closed door. If you see a two-inch separation in the coil, that’s your break.
- The door only opens a few inches and then stops. The opener is pushing against the full weight of the door because the spring isn’t doing its job. Continuing to run the opener this way burns out the motor and strips the gears inside.
- The cables look loose or have jumped the drum. When the torsion spring breaks, the lift cables lose tension instantly. A dangling cable or one that’s wound over itself on the drum is a tell-tale sign the spring let go first.
- The door slams hard when it closes, even with the opener attached. The spring controls the descent as much as the lift. A worn spring lets the door drop faster than it should, which stresses every hinge and roller on the way down.
Replacement Cost & What’s Included
A Craftsman torsion spring replacement in Tarzana runs $180 to $340, installed. The spread comes down to spring size: a single spring on a lightweight 7-foot door lands near the bottom of that range, while a pair of heavy-duty springs on a 16-foot or custom door pushes it toward the top. Every quote includes both springs replaced as a matched pair, which is how the job should always be done. When one goes, the other has the same number of cycles on it and is usually weeks behind. You’re also getting the labor to unwind and rewind the springs, reset the cables and drums, balance the door, lubricate the assembly, and test the full cycle by hand and with the opener. The price we quote on the phone is the price on the invoice. Period. And the whole job is covered by our 90-Day Done Right Promise: if it’s not done right, we make it right, one call to me personally. You’ll also get the $40 Off Any Repair Over $200 offer and, if you’re a senior or veteran, the standing 10% discount.
DIY or Call Us?
Here’s the honest split. You can safely check whether the spring is broken by looking up at the shaft with the door closed. You can test the balance by pulling the release cord and lifting the door by hand. What you cannot safely do is wind or unwind a torsion spring with a pair of bars from Harbor Freight and a prayer. The spring is under hundreds of pounds of torque. One slip and that bar becomes a projectile. A door is 200 pounds riding on two springs. Respect it. We carry a full range of Craftsman-compatible springs on the truck, so if you call us before noon, there’s a good chance your door is working before the school bus rolls by. Call (818) 431-2466 and Otto will tell you what it’s doing wrong and what it actually needs. Those two things aren’t always the same.

FAQs
Most Craftsman torsion springs are rated for 10,000 cycles, which works out to 8 to 12 years for a typical Tarzana homeowner who opens their door three or four times a day. Springs with a 20,000-cycle rating can push that to 15 to 20 years. Tarzana’s dry heat doesn’t rust springs the way coastal air does, but the repeated thermal expansion from our hot garage interiors does take a toll on the coil’s molecular structure over time. The best way to know what’s left on yours is to count the cycles, same way you’d count tire miles. Call us for an inspection and Otto will tell you exactly what’s left.
No. A broken torsion spring cannot be repaired, welded, spliced, or otherwise coaxed back into service. The steel has failed at a stress point. The only safe and correct fix is a full replacement, and we always replace both springs as a matched pair so the door lifts evenly and the opener doesn’t strain. Call (818) 431-2466 for an exact quote. Estimates are free.
A standard two-spring replacement on a single door in Tarzana takes 45 to 90 minutes from the time the truck parks to the time we hand you the invoice. That includes unwinding the old springs, installing the new pair, resetting the cables, balancing the door, and running it through a full cycle test. If you call before noon, we’ll usually have it done same day.
We stock a full range of torsion springs on the truck in common sizes that cover nearly every Craftsman door we see in Tarzana, from single-car to oversized double doors. If you have an unusual size, we’ll have it in hand the next business day. Either way, we’ll tell you the timeline before any work starts. Call (818) 431-2466 and we’ll confirm what your door needs.
