OEM vs Aftermarket
Garage Door Spring Cost
The OEM premium is real but rarely justified. Here is when the original-equipment part is mandatory, when a quality aftermarket spring is the better economic call, and how to spot the difference on the invoice.
Headline number: OEM springs add $40 to $100 over aftermarket on a standard residential pair. Proprietary systems (Wayne Dalton TorqueMaster) can add $150 to $300.

What OEM actually means in spring parts
OEM stands for Original Equipment Manufacturer. In the garage door world, an OEM spring is one supplied by the same manufacturer that made the door (Clopay, Amarr, Wayne Dalton, Garaga, Haas, CHI). The packaging is branded, the part number ties back to the manufacturer's catalogue, and the installer can order it from the manufacturer or from authorised dealers.
Aftermarket means any spring manufactured by a third-party supplier and engineered to match the specifications of the original. Major aftermarket suppliers (Service Spring, IDC Spring, Holmes Garage Door Company, DURA-LIFT) sell springs that meet or exceed the same DASMA specifications as the OEM equivalent. The wire is the same oil-tempered steel, the manufacturing tolerances are the same, and the cycle ratings are the same.
Why aftermarket is usually fine
Garage door springs are a relatively simple commodity component. The wire material, the manufacturing process, and the engineering specifications are well-standardised across the industry through DASMA guidance. Both OEM and aftermarket springs from reputable suppliers come off the same kinds of spring-winding machines, use the same kinds of steel wire, and undergo similar quality control. The performance difference in field service is, by all available data, minimal.
Aftermarket springs are also commodity-priced because of the competitive supplier market. A standard 10,000-cycle torsion spring sold by Service Spring or IDC Spring costs the contractor $20 to $30 wholesale. The same nominal spring sold under a Clopay or Amarr OEM label costs the contractor $35 to $55 wholesale. The retail markup is similar, so the retail price difference is roughly $40 to $100 per pair for an aftermarket vs OEM standard spring replacement.
For most residential customers replacing standard torsion or extension springs, aftermarket is the smart economic choice. The performance is equivalent, the warranty is often similar (one to five years from major aftermarket suppliers), and the savings are real.
When OEM is genuinely required
Proprietary spring systems. The most common is the Wayne Dalton TorqueMaster, an enclosed-shaft torsion system where the spring is sealed inside a metal tube above the door. The TorqueMaster spring is engineered as an assembly with the shaft and cannot be swapped out independently. Replacement requires the OEM TorqueMaster spring assembly, which costs $120 to $200 per spring (against $40 to $80 for a standard aftermarket equivalent). Labor is also longer because the assembly requires more careful handling.
Doors under active manufacturer warranty. Some premium residential door lines (Clopay Avante, Garaga Standard+, certain Amarr Premium series) carry extended warranties of 7 to 10 years on the door system. Some of those warranties require OEM parts for any in-warranty service to maintain coverage. Read the warranty terms. If OEM is required and the door is still in its warranty window, the OEM premium is warranted in order to preserve the larger warranty value.
Commercial or industrial doors with non-standard spring specifications. Large commercial roll-up doors, jackshaft-operated overhead doors, and high-lift configurations often use spring systems with no aftermarket equivalent. The OEM is the only supplier. Parts cost is whatever the manufacturer charges, which is rarely competitive but is the only option.
The Wayne Dalton TorqueMaster wrinkle
Wayne Dalton sold residential doors with the TorqueMaster system extensively from the late 1990s through the mid-2010s. The system was marketed as safer (the spring is enclosed and cannot fly across the garage if it breaks) and quieter than standard exposed torsion springs. The trade is that the proprietary spring assembly is more expensive and replacement labor is longer.
For Wayne Dalton homeowners with a TorqueMaster door, spring replacement options are limited. The OEM TorqueMaster spring is the standard answer. Some installers will convert the door to a standard external torsion system, which removes the proprietary lock-in but adds $200 to $400 for the conversion hardware. The conversion is worth considering if the homeowner plans to keep the door for another decade and wants to avoid future OEM premiums.
How to ask for what you want
When the contractor arrives and quotes the spring replacement, ask directly: "Are these OEM or aftermarket springs?" A reputable contractor will tell you immediately. If the contractor is using aftermarket, ask which manufacturer (Service Spring, IDC Spring, and Holmes are the most common in the North American residential market). If the contractor is using OEM, ask why (proprietary system, warranty preservation, customer preference) and whether an aftermarket alternative is available at lower cost.
For most standard residential doors, you should be able to request aftermarket and receive a meaningful quote reduction. If the contractor insists on OEM without a specific technical reason, that is a flag. Either they only stock OEM (in which case ask whether they can source aftermarket on request) or they are using the OEM label as a margin-protection lever.
What to ask before booking
- Are the springs OEM or aftermarket?
- What is the manufacturer (for aftermarket: Service Spring, IDC, Holmes, etc.)?
- Is OEM required for my door (proprietary system or active warranty)?
- What is the price difference between OEM and aftermarket for my door?
- What is the parts warranty on each option?
- For Wayne Dalton owners: is conversion to standard torsion an option?

Frequently Asked
Are OEM garage door springs better than aftermarket?
For most standard torsion and extension springs, no. Aftermarket springs from reputable manufacturers (Service Spring, IDC Spring, Holmes) meet or exceed the same DASMA specifications as OEM equivalents. For proprietary systems like Wayne Dalton TorqueMaster, the OEM part is required because the system is engineered around it.
How much more does an OEM spring cost?
OEM springs typically cost 30 to 60 percent more than aftermarket equivalents. On a residential pair replacement, the premium is roughly $40 to $100 over an equivalent aftermarket install. For proprietary systems where OEM is required, the absolute cost is much higher because the parts are not commodity-priced.
When is OEM actually required?
Three scenarios. First, proprietary spring systems like Wayne Dalton TorqueMaster where the spring is integrated into a sealed shaft assembly. Second, doors under active manufacturer warranty where the warranty requires OEM parts. Third, commercial or industrial doors with non-standard spring specifications where the OEM is the only supplier.
Will using aftermarket void my door warranty?
Almost always no for standard residential doors, where the manufacturer warranty (typically 5 to 10 years on the door itself) is separate from the spring system. Spring is considered a wear item and is not under door warranty. For commercial doors and some premium residential lines under extended warranty, OEM may be required. Read your warranty terms or call the manufacturer to check.
Can I tell if my installer is using OEM or aftermarket?
Ask. Reputable installers will tell you directly and show you the part packaging if requested. OEM parts arrive in branded manufacturer packaging (Clopay, Amarr, Wayne Dalton, Garaga). Aftermarket parts arrive in supplier packaging (Service Spring, IDC Spring, Holmes). The spring itself usually has no visible branding, so packaging is the easiest tell.
