Converting your single-wheel truck to a dually setup offers significant advantages, particularly for those hauling heavy loads or needing enhanced towing capacity. However, it's a significant modification requiring careful planning and execution. This comprehensive guide will walk you through everything you need to know about single wheel to dually conversion kits.
What is a Single Wheel to Dually Conversion Kit?
A single wheel to dually conversion kit provides all the necessary components to transform your single-rear-wheel (SRW) truck into a dual-rear-wheel (DRW) configuration. These kits typically include:
- Inner wheels and tires: Matching your existing wheels and tires for a uniform look.
- Hubs and mounting hardware: Specifically designed to fit your truck's axle.
- Wheel spacers (sometimes): Depending on the kit and your specific truck model, these may be included to ensure proper spacing and alignment.
- Brakes (possibly): In some cases, upgraded brakes may be necessary to handle the increased weight capacity. This often isn't included in basic kits.
- Fender flares (often sold separately): To accommodate the wider track width of the dual wheels, these are usually purchased in addition to the kit.
What are the Benefits of Converting to a Dually?
The primary advantage of a dually conversion is the increased payload and towing capacity. The extra wheels distribute the weight more evenly, reducing strain on the truck's components and improving stability. This makes it ideal for:
- Heavy-duty towing: Hauling large trailers, boats, or RVs becomes significantly safer and more manageable.
- Increased payload capacity: You can carry heavier loads in the truck bed without compromising safety.
- Improved stability: The wider track width enhances stability, especially on uneven terrain or at high speeds with heavy loads.
What are the Disadvantages of a Dually Conversion?
While the benefits are substantial, there are also some drawbacks to consider:
- Increased cost: Conversion kits, along with installation, can be expensive.
- Reduced fuel economy: The added weight and increased rolling resistance lead to slightly lower fuel efficiency.
- Increased turning radius: The wider track makes turning slightly more difficult, particularly in tight spaces.
- Potential for rubbing: Improper installation or incorrect kit selection can lead to wheel rubbing on the fenders or other parts.
What parts do I need for a dually conversion?
This depends heavily on the year, make, and model of your truck. A complete kit will usually include the inner wheels and tires, mounting hardware, and potentially wheel spacers. However, you will almost certainly need to purchase new fender flares separately to accommodate the wider wheelbase. You may also need upgraded brakes, depending on the weight capacity you are aiming for. It's crucial to consult with a professional installer or parts supplier to determine the precise parts needed for your specific truck.
How much does a single wheel to dually conversion cost?
The cost varies significantly depending on the truck make, model, and year, as well as the brand and quality of the conversion kit. Expect to pay anywhere from a few thousand dollars for a basic kit and installation to several thousand more for a high-end kit with upgraded brakes and professional installation. Remember to factor in the cost of fender flares, which are usually sold separately.
Can I install a dually conversion kit myself?
While some individuals with extensive mechanical experience may attempt a DIY installation, it's generally recommended to have the conversion professionally installed. The process is complex and requires specialized tools and knowledge to ensure proper alignment and safety. An incorrect installation can lead to dangerous situations.
Will a dually conversion void my warranty?
This depends entirely on your truck's warranty and the terms and conditions. Modifications like this may void certain parts of your warranty, particularly those related to the drivetrain or suspension. Always consult your vehicle's warranty documentation or your dealership before undertaking the conversion.
How much does it affect gas mileage?
Expect a slight reduction in gas mileage. The added weight of the additional wheels and tires, coupled with increased rolling resistance, will impact fuel economy. The exact amount of reduction will vary depending on several factors, including the weight of the conversion kit, driving habits, and terrain.
This comprehensive guide helps clarify the process and considerations involved in a single-wheel to dually conversion. Remember to consult professionals for accurate part identification and safe installation to avoid potential issues.
