Wheel extender

Types of Wheel Extender

A wheel extender is a simple mechanical tool that is attached to the hub of a vehicle. It is designed to push the wheel outward, away from the vehicle. Car wheel spacers can be used for a variety of reasons, but they are often fitted to improve a car's handling, increase its stability and make it more visually appealing.

Wheel extenders come in different types based on construction, size, and bolt pattern.

• By Construction

  Slip-On Wheel Extenders: Slip-on extenders have a simple design. They slide onto the wheel's hub and fit over the wheel's lug bolts. This type of extender requires the lug nuts to be tightened to secure the wheel in place. Slip-on extenders are usually thinner and can provide a tighter fit.

  Bolt-On Wheel Extenders: Bolt-on wheel extenders are thicker than slip-on extenders. They are attached to the wheel hub using bolts. Then, additional studs are installed on the face of the extender, allowing the wheel to be mounted securely. Bolt-on extenders are more stable and are often used for off-road vehicles.

• By Size

  Thin Wheel Extenders: Thin extenders are typically 5 to 15 mm thick. They are used to slightly adjust the car's handling or aesthetics without affecting the vehicle's performance. They are mostly used on sports cars or luxury vehicles.

  Standard Wheel Extenders: Standard extenders measure 15 to 25mm. They provide a noticeable change in the vehicle's stance and improve its handling. They are mostly fitted on trucks and off-road vehicles.

  Large Wheel Extenders: Large wheel extenders are 25 mm and above. They drastically change the vehicle's appearance and widen the wheelbase significantly. Large extenders can also be used to prevent the wheels from rubbing against the car's body. They are commonly fitted on modified vehicles.

• By Bolt Pattern

  5-Bolt Wheel Extenders: 5-bolt extenders are the most common type. They fit a wide range of passenger vehicles, including sedans, hatchbacks, and SUVs. They come in different bolt patterns, such as 5x100 mm, 5x110 mm, and 5x120 mm. The specific bolt pattern should match the vehicle's wheel hub for a proper fit.

  6-Bolt Wheel Extenders: 6-bolt extenders are less common and mainly used on trucks, vans, and some high-performance sports cars. They also come in different bolt patterns, such as 6x114 mm, 6x120 mm, and 6x139.7 mm.

Specification and Maintenance of Wheel Extender

When buying a wheel extender, there are many specifications to consider to make sure the product meets the intended needs. Here are some of the key specifications.

• Width

  The width of the wheel extender is one of the most important specifications to consider. It determines how far the tires will stick out from the fender. It comes in different sizes, and the choice should depend on how much one wants to achieve the wheel's clearance. A wider extender can offer more protection against debris but may result in increased wind noise and drag.

• Length

  The length of the wheel extender is equally important. This is because it dictates how far the wheels will protrude beyond the vehicle's body. A longer extender can enhance a car's stability on uneven terrains by providing a wider track. However, it may affect the turning radius and could potentially scrape the bodywork on tight turns.

• Material

  Different materials are used to make wheel extenders, and each comes with its advantages. Some of the common materials include steel, ABS plastic, and aluminum. Steel is strong and durable. It can withstand rough use. ABS plastic is lightweight and affordable. Aluminum is resistant to corrosion, making it a suitable choice for off-road conditions.

• Fitment

  Wheel extenders come in different sizes to fit various vehicle models. When choosing the right-sized extender, consider the bolt pattern, pitch diameter, and thread type. The right fitment is very important as it enhances the performance and safety of the vehicle.

Maintaining a wheel extender is very important as it ensures durability, performance, and safety. Here are some important maintenance tips.

• 1. Inspect the extenders regularly for signs of wear or damage. This includes checking for cracks, loose bolts, and distortion. Do this especially after off-road adventures or long trips on rough roads.
• 2. Make sure that the wheel extender is correctly installed. Follow the manufacturer's instructions or have it done by a professional. Improper installation can cause serious damage to the vehicle.
• 3. Clean the wheel extender regularly to prevent the build-up of dirt, mud, and debris. Use a soft brush and mild detergent to remove the dirt. Avoid using harsh chemicals that can damage the material.
• 4. Lubricate the bolts and threads of the wheel extender to prevent rust and ensure smooth operation. Use a suitable lubricant and wipe off any excess to prevent dirt from sticking.
• 5. Avoid overloading the vehicle, as this can put excessive pressure on the wheel extender and lead to premature wear or failure.

How to Choose Wheel Extender

• Purpose

  Consider why the vehicle needs wheel spacers. Is it for off-road driving, improving the car's look, or making it more stable when turning?

• Vehicle Compatibility

  The spacer should fit well with the car's make, model, and year. Check the owner's manual or talk to an expert to find the right size.

• Quality and Material

  Choose spacers made from strong materials like forged aluminum or high-quality steel. These last a long time and keep the wheels straight.

• Thickness

  Wheel spacers come in different sizes. A thicker spacer moves the wheel out more. But it can cause problems if it rubs against parts of the car. Measure carefully and pick a size that works well.

• Type of Wheel Extender

  There are two main kinds of spacers. Bolt pattern adapters change the number of bolts on the hub. Slip-on spacers go between the wheel and the hub. Think about which type is best for the vehicle.

• Offset

  The offset is how far the spacer pushes the wheel out. A higher offset means the wheel sticks out more. But it can affect how the car drives. Ask a mechanic what offset is good for the vehicle.

• Load Rating

  Each spacer can support a certain amount of weight. This is called the load rating. Make sure the rating is high enough for the vehicle. If the spacer is too weak, it can break or cause an accident.

• Installation

  Installing the spacer correctly is very important. If not, the wheels could come loose. Follow the instructions carefully. Or take it to a professional to put on the spacer right.

• Brand Reputation

  Choose spacers from well-known companies that many people trust. Look up reviews to see what others think of the quality and service.

• Price

  Set a budget for the wheel spacer. Remember, sometimes a higher price means better quality. But expensive does not always mean best. Find a spacer that is good quality and fits the budget.

How to DIY and replace wheel extender

Most wheel extenders come with installation instructions that are easy to follow. Below are the general steps on how to install a 5 lug wheel spacer:

• Preparation

  Park the car on a flat surface and engage the parking brake. Loosen the lug nuts and raise the vehicle with a jack. A jack stand is placed under the vehicle for extra safety. The wheel is removed by taking off the lug nuts.

• Clean the hub

  The hub's surface where the wheel sits is cleaned. This ensures a tight fit and prevents wobbling.

• Align the spacer

  The wheel spacer is placed on the hub. The holes on the spacer are aligned with the holes on the hub. This is usually easy for a wheel spacer because it is flat. The extender's bolts are inserted into the holes and hand-tightened.

• Attach the wheel

  The wheel is placed over the wheel spacer. The lug nuts are screwed on the bolts. The car is lowered onto the ground, and a torque wrench is used to tighten the lug nuts securely. The manufacturer’s torque specifications are followed.

• Check everything is secure

  After driving for about 50 miles, the wheel is checked to ensure the lug nuts are still tight. The process is repeated for the other wheels.

Q&A

Q1: Do wheel extenders need maintenance?

A1: Wheel extenders do not require maintenance, but it is essential to check the bolts regularly. Ensure the bolts are tight and secure to prevent any problems or accidents when driving.

Q2: How long do wheel extenders last?

A2: Wheel extenders can last for many years, just like other car parts. Their lifespan relies on how well they are installed, the quality of the extender, and how it is used.

Q3: Do wheel extenders affect driving?

A3: Yes. It might be difficult to park in small spaces because the wheels stick out further. Additionally, the car's weight distribution may change, making it less stable in turns.
