1. A1 Electric Power Window Conversion Kit: Best Overall
In our evaluation, the A1 Electric Power Window Conversion Kit stands out as a top performer. Based on owner feedback and the spec sheet, the high-torque motor provides consistent lifting power even for heavier windows. The wiring harness is well-labeled, which simplifies installation for DIYers. Many owners noted that the kit fits most vehicles with minimal adjustments, though some older models may require slight modifications to the door panel or regulator mounting points.
However, this kit is not ideal for vehicles with complex factory wiring or those seeking a completely seamless OEM look. If your car has unusual door dimensions or you prefer a fully integrated switch panel, you might want to look elsewhere. The plastic switch housings feel sturdy but not premium, so those wanting a luxury feel should consider other options.
- Universal fit for most vehicles with manual crank windows; includes detailed installation manual.
- High-torque motor tested for over 10,000 cycles based on manufacturer claims and owner reports.
- Plug-and-play wiring harness with color-coded wires and relay protection.
Pros: Smooth and quiet operation; Comprehensive installation instructions
Cons: Some users reported needing to modify door panels for perfect fit
2. Dorman 761-600 Power Window Conversion Kit: Best Durability
The Dorman 761-600 is a strong contender, especially for those prioritizing longevity. Based on owner feedback and the spec sheets, the use of metal gears in the motor assembly significantly reduces wear compared to nylon gears found in many competitors. We found that this kit is particularly popular among truck and SUV owners who need reliable operation in demanding conditions. The wiring is straightforward, and the kit includes everything needed for a two-door conversion.
That said, the included switches have a plasticky feel and may not match the interior aesthetics of higher-end vehicles. If you care deeply about switch feel and appearance, you might want to purchase aftermarket switches separately. Also, some owners noted that the motor can be slightly louder than premium kits, though it remains acceptable for most users.
- Robust motor assembly with metal gears for extended lifespan.
- Comes with both left and right door components for a complete front conversion.
- Includes easy-to-follow instructions and all necessary hardware.
Pros: Metal gears enhance durability; Good customer support from Dorman
Cons: Switches feel a bit cheap
3. Spal Power Window Kit 4-Door: Best for 4-Door Cars
For those converting all four doors, the Spal Power Window Kit offers a comprehensive package. In our evaluation, the pre-wired relay box is a standout feature, as it centralizes the electrical connections and reduces the risk of shorts. Based on owner feedback, the motors provide consistent power even with larger windows. The kit is universal but works best on vehicles with standard door layouts.
However, the installation is not for the faint of heart. The wiring diagram can be confusing for novices, and some owners reported needing to drill additional holes for mounting. If you are not comfortable with basic automotive electrical work, you may want to hire a professional. Also, the switch panel design is basic and may not blend well with all interiors.
- Designed for four-door conversions with independent motor control.
- Pre-wired relay box simplifies electrical connections and reduces wiring errors.
- Motors are rated for continuous duty, suitable for frequent use.
Pros: Complete 4-door solution; Relay box improves safety
Cons: Installation can be time-consuming for beginners
4. OEM Power Window Kit by ACI: Best OEM Feel
The ACI OEM Power Window Kit is tailored for those who want a factory-like finish. Based on the spec sheet, the switch plates are molded to resemble OEM designs, and the included weather seals help protect the motor from moisture. Owner feedback indicates that the installation is straightforward for compatible vehicles, with many noting the clean look of the final result.
However, this kit has a narrower fitment range. It is designed for specific makes and models, so you must check compatibility before purchasing. Some users reported that the motor speed is slightly slower than aftermarket alternatives, which may be a concern for those with heavy windows. If your vehicle is not listed as compatible, this kit is not a good choice.
- Switch plates designed to mimic factory appearance for a seamless look.
- Includes weather seals to protect against moisture ingress.
- Motors are pre-assembled to brackets for easier installation.
Pros: OEM-style switch plates; Weather seals included
Cons: Not universal; limited vehicle compatibility
5. Electric Life Power Window Kit: Best Value
For budget-conscious buyers, the Electric Life Power Window Kit offers a cost-effective entry into power windows. Based on owner feedback, the kit works reliably for light to moderate use, and the compact motors fit easily into most doors. The wiring is simple, making it a good choice for first-time installers. In our evaluation, the value proposition is strong for those on a tight budget.
However, the use of plastic gears in the motor means it may not last as long as metal-gear alternatives. Some owners reported slower operation after a few months of heavy use. This kit is best for vehicles that are not daily drivers or for those who are willing to replace parts sooner. If you need long-term durability, consider spending more.
- Affordable option for two-door conversions without sacrificing basic performance.
- Includes simple wiring harness with inline fuses for circuit protection.
- Motors are compact and fit most standard door cavities.
Pros: Very affordable; Compact motor design
Cons: Plastic gears may wear faster
6. Power Window Kit by A-Team Performance: Easy Install
The A-Team Performance Power Window Kit is designed with the DIY installer in mind. In our evaluation, the pre-terminated wires and color-coded connectors significantly reduce the chance of wiring errors. Based on owner feedback, the included video link helps clarify steps that might be confusing in text. The adjustable brackets also simplify alignment.
However, the motor power is only average, and some owners noted that it struggles with larger or heavier windows. The plastic components feel less robust than higher-priced kits. This kit is a good choice for small to medium cars where ease of installation is a priority, but it may disappoint owners of trucks or SUVs with heavy glass.
- Pre-terminated wires with color-coded connectors reduce wiring complexity.
- Includes a detailed installation video link for visual guidance.
- Mounting brackets are adjustable to fit various door configurations.
Pros: Installation-friendly design; Good instructions
Cons: Motor power is average
7. Xtreme Power Window Conversion Kit: Budget Pick
The Xtreme Power Window Conversion Kit is the most affordable option we evaluated. It is suitable for those who just need basic power window function without frills. Based on owner feedback, it works adequately for occasional use in small cars. The lightweight design can be an advantage for older doors with weak springs.
However, the lack of a relay means the full current passes through the switch, which can lead to voltage drop and slower operation. Durability is a concern, with several owners reporting motor failure within a year. This kit is only recommended for budget builds where reliability is not critical, or as a temporary solution. We suggest skipping this if you plan to keep the vehicle long-term.
- Entry-level price point for basic power window functionality.
- Simple two-wire motor design (no relay) for quick hookup.
- Lightweight components reduce strain on door panels.
Pros: Lowest cost option; Lightweight
Cons: No relay; may cause voltage drop
Frequently Asked Questions
Are aftermarket power window kits universal?
Most aftermarket power window kits are designed to be universal, but fitment can vary. We recommend measuring your door cavity and regulator mounting points before purchasing. Some kits include adjustable brackets to improve compatibility, but you may still need to modify door panels or drill new holes.
How difficult is it to install a power window kit?
Installation difficulty ranges from moderate to challenging, depending on your vehicle and the kit. Basic kits with pre-wired harnesses are easier, but you should have experience with automotive wiring and door panel removal. Expect to spend 2-4 hours per door for a first-time install.
Do I need to upgrade my car's electrical system for a power window kit?
In most cases, no. Aftermarket power window kits draw relatively low current (typically 10-20 amps per door) and work with the existing battery and alternator. However, if you have a very old vehicle with a weak charging system, ensure the battery is in good condition.
Can I install a power window kit on a vehicle with manual windows that originally had power windows?
Yes, but you may need additional parts like the original wiring harness or switch bezels. Many aftermarket kits are designed to replace manual regulators, but the door panels might already have cutouts for switches. Check compatibility before buying.
How long do aftermarket power window motors last?
Based on owner feedback and manufacturer claims, quality motors can last 5-10 years with normal use. Motors with metal gears tend to outlast plastic-gear units. Proper installation and occasional lubrication can extend lifespan.
Our Verdict
After researching and comparing these seven kits, our top pick is the A1 Electric Power Window Conversion Kit for its overall balance of performance, durability, and ease of installation. For those seeking maximum longevity, the Dorman 761-600 is an excellent runner-up with its metal-gear motor. Choose based on your vehicle type and budget.
