What is a Strut Spreader Tool?

Before we get into the specifics of the ReluxGo model, let’s clarify what a strut spreader tool actually does. On many modern vehicles, especially those from European manufacturers like Volkswagen, Audi, and BMW, the suspension strut is clamped tightly into the steering knuckle.

This design is robust, but it makes removing the strut a real challenge. The fit is so precise that you can’t simply pry it apart without risking damage to the knuckle, the strut, or yourself. A strut spreader tool directly addresses this problem. It’s a small, specialized tool designed to fit into the split of the steering knuckle.

When you turn the tool’s bolt, it has a cam-like action that gently and evenly widens the gap in the knuckle. This releases the clamping force holding the strut, allowing it to slide out with minimal effort. The effectiveness of the tool depends on the shape of the bit, which can be oval, flat, or other designs, as different strut spreader tools use various bit shapes to spread the knuckle safely and efficiently.

Who needs one? It is crucial for anyone dealing with strut issues.

DIY Mechanics: Anyone planning to replace struts, shock absorbers, or coil springs on a compatible vehicle will find this tool indispensable.
Professional Technicians: For professionals, time is money. This tool significantly accelerates suspension work, enhancing efficiency and minimizing the risk of damage to customer vehicles.
Automotive Students: Learning with the correct tools is crucial. A strut spreader is a perfect example of a specialized tool that teaches the importance of working smarter, not harder.

Without this tool, mechanics often resort to less elegant methods like hammering chisels, allen wrenches, or pry bars into the knuckle. These techniques can easily damage the aluminum or cast-iron knuckle, leading to expensive repairs and compromising the vehicle’s safety. A dedicated strut spreader is the professional and safe way to perform the job.

The Importance of a Spreader Tool

When it comes to working on the suspension of cars, especially popular models like BMWs and Audis with a strong drive ,the strut spreader tool quickly proves itself as a must-have in any toolkit. Removing or installing struts can be a pretty challenging task, and using the right tool makes all the difference.

While some might be tempted to reach for an allen wrench, chisel, or even try to grind down an adapter or insert to fit, these improvised solutions rarely deliver the precision or safety needed for the job. In fact, using the wrong tool can easily damage the strut, the knuckle, or even cause injury.

A dedicated strut spreader tool is explicitly designed to handle the force required to safely compress and spread struts. Look for a tool made from strong metal, ideally with a robust drive system. Many feature a 1/2” drive, making them compatible with a wide range of drive tools you might already have in your workshop. This versatility is especially valuable for both professional mechanics and DIY enthusiasts who want to ensure their tools fit a variety of jobs and vehicles.

If you’re tackling a DIY project, remember to take your time and don’t rush the process. It’s always wise to search for advice from experienced mechanics or online forums, especially if you’re working on a car for the first time.

The right spreader tool not only makes the work easier but also helps you avoid costly mistakes. In some cases, you might find that a specific adapter or insert is needed for your vehicle’s strut design, so double-check compatibility before you buy.

Shopping for a strut spreader tool can also be a smart move in nov, as many online retailers offer discounts and promotions during this time. When searching for the best deal, consider the location of the seller and the estimated delivery time. Some sellers may offer free shipping or bulk discounts, which can be a bonus if you’re outfitting a larger workshop.

Ultimately, investing in a quality strut spreader tool for quick pickup is a decision that pays off every time you work on suspension components. It saves time, reduces frustration, and helps ensure a professional result, leaving you free to focus on the rest of your project with confidence. Whether you’re a seasoned mechanic or just starting your DIY journey, having the right spreader tool in your arsenal is essential for safe, efficient, and successful strut work.

Key Features of the ReluxGo Strut Spreader

The ReluxGo Strut Spreader Tool, while simple in design, packs several features that make it a compelling option for both amateurs and pros. Based on its specifications and user feedback, here are the standout characteristics, including its versatile adapter option.

Wide Vehicle Compatibility

One of the tool's biggest selling points is its broad application with various adapter options . The strut spreader tool is designed to be compatible with a wide range of vehicles that use a clamped strut housing design. The manufacturer explicitly lists compatibility with:

Audi
BMW
Citroën
Ford
Peugeot
Volkswagen

This covers a significant portion of the cars on the road, particularly popular European models known for this type of suspension setup. Its "universal" claim suggests it may work on other makes as well, provided the knuckle gap is similar. However, it's always wise to verify fitment for your specific vehicle in each case, as one customer noted it did not fit their 2011 Audi Q5, where the gap was less than 5mm.

Premium Material and Construction

A strut spreader tool designed to exert force needs to be strong. ReluxGo addresses this by constructing the tool from durable metal, specifically AISI 1045 medium carbon steel. This material is known for its high hardness and strength.

The tool is also heat-treated, which further increases its durability and resistance to wear and deformation under pressure. The finish is designed to be corrosion-resistant, which is crucial for a tool that will be exposed to the harsh environment of a workshop. This focus on robust materials ensures a long service life, even with regular professional use.

Ease of Use and Design

The ReluxGo tool is engineered for simplicity. Its compact, single-piece design makes it easy to handle in the tight confines of a wheel well. The operating principle is straightforward: insert the bit into the knuckle's slot and turn the 10mm hex head.

This intuitive operation significantly lowers the learning curve. The tool effectively turns a potentially difficult, multi-person job into a manageable one-person task. By providing controlled and even pressure, it removes the guesswork and brute force from strut removal.

How to Use the ReluxGo Strut Spreader Tool

Using the tool is simple, but following the correct procedure and safety precautions for the bit is essential for a successful and damage-free repair.

Safety First:

Always wear safety glasses and gloves.
Ensure the vehicle is securely supported on jack stands. Never work under a vehicle supported only by a jack.
Chock the wheels that remain on the ground to prevent the vehicle from rolling.

Step-by-Step Guide:

Prepare the Vehicle: Raise the vehicle and remove the wheel to gain access to the suspension components.
Clean the Area: Before inserting the tool, thoroughly clean the steering knuckle area, especially the slot where the tool will be inserted. Use a wire brush to remove any rust, dirt, or debris. A clean surface ensures the tool seats correctly.
Loosen the Pinch Bolt: Locate the pinch bolt that clamps the steering knuckle around the strut. Loosen and remove this bolt and nut completely.
Insert the Tool: Insert the spreader tip of the ReluxGo tool into the now-empty slot in the steering knuckle. You may need to tap it in gently with a hammer to ensure it is fully seated.
Spread the Knuckle: Using a 10mm wrench or socket, slowly turn the hex head on the tool clockwise. You will feel resistance as the tool begins to spread the knuckle. The manufacturer specifies a maximum torque of 13 Nm (approximately 9.6 ft-lbs). It is critical not to exceed this torque to avoid damaging the tool or the knuckle.
Remove the Strut: As you turn the tool, the gap will widen, releasing the pressure on the strut. You should now be able to push down on the lower suspension arm and slide the strut assembly up and out of the steering knuckle.
Remove the Tool: Once the strut is free, turn the hex head counter-clockwise to retract the spreader tip and remove the tool from the knuckle.

Important Note: The manufacturer recommends keeping the threads of the tool clean and lightly lubricated to continue its smooth operation . This will ensure smooth operation and prevent the threads from galling or seizing under load.

Weighing the Pros and Cons

No tool is perfect. Here’s a balanced look at the strengths and weaknesses of the ReluxGo Strut Spreader Tool.
