Garage Door Springs & Wires

Measure the door weight, height, and track type; note whether the springs are torsion (mounted above the door) or extension (mounted along the sides) and record the spring length, wire diameter, and inner diameter or the cable diameter and length. Consult manufacturer or sizing charts with those measurements to match replacement springs or cables to the door’s weight and cycle rating

Garage springs and cables store high tension and can cause serious injury if released improperly; use the correct winding bars, secure the door, wear eye protection, and follow torque and installation procedures exactly. If you are unfamiliar with spring winding or lack proper tools, hire a trained technician

Choice depends on your door and existing hardware: torsion springs mount on a shaft above the door and offer smoother, longer-lasting operation and easier balancing, while extension springs run along the door sides and are often less expensive but may require safety cables and more frequent replacement. Match the replacement type to the original system unless converting with appropriate hardware and expertise

Replacement parts generally range from budget options under $50 for simple cables or single extension springs to higher-quality torsion spring kits and cables that can cost over $100, with an average around $80 across the category. Look for corrosion-resistant coatings, correct cycle ratings (10k, 20k cycles), and heavy-gauge wire or braided cable for durability

Perform regular inspections for corrosion, fraying, or gap in coils; lubricate torsion springs and bearings with a light garage-door lubricant every 6–12 months; maintain balanced door operation to avoid extra strain; and replace worn cables or springs promptly to prevent further damage

Kits often include replacement springs, cables, center brackets, and mounting hardware; higher-end kits may include winding cones for torsion springs. Additional tools usually required are winding bars for torsion springs, adjustable wrenches, pliers, a level, clamps or locking pliers to secure the door, and safety gear

Replace both springs if one has failed and the other shows similar age, wear, or cycle count, because springs installed together typically share the same lifespan and the remaining spring is likely to fail soon after; replacing both ensures balanced operation and reduces repeat labor
