Installation Guide and Best Practices
Proper installation is crucial to ensuring the optimal performance and longevity of the ARANA gas struts. The following steps outline the recommended installation process, based on the manufacturer’s guidelines and user experiences from the RX-7 community:
Pre-Installation Considerations
Before beginning the installation, it is important to assess the specific requirements of the application. The ARANA 23-inch struts are designed for lids that are between 34.5 and 46 inches in width. It is also essential to measure the weight of the lid or door being supported. These struts are rated for 35 pounds of operating force and are suitable for lids weighing between 26 and 39 pounds. Using them on lids outside this range may result in improper function, such as the lid not holding in the open position or being too difficult to close.
Mounting hardware is not included with the ARANA gas struts, so it is important to select appropriate screws or bolts based on the material being used (e.g., wood, metal). The manufacturer’s manual provides guidance on the types of hardware that are suitable for different applications.
Step-by-Step Installation
Positioning the Struts: The positioning of the gas struts is critical to their performance. The manufacturer recommends trial and error to determine the optimal placement, particularly for custom or non-standard applications. The struts should be positioned so that they do not bottom out before the lid is fully closed, and the lid should open to the desired angle (e.g., 90 degrees) without overextending the struts.
Mounting the Struts: The L-shaped mounting brackets included in the package should be attached to the lid and the frame or support structure. The brackets are designed to provide a secure and stable mounting point for the gas struts. It is important to ensure that the mounting points are aligned correctly to avoid misalignment or binding during operation.
Connecting the Struts: Once the brackets are in place, the gas struts can be attached. The manufacturer’s manual provides detailed instructions on how to connect the struts to the brackets using the M8 nuts included in the package. It is important to follow these instructions carefully to ensure a secure and stable connection.
Testing the Installation: After the struts are installed, it is important to test their performance. The user should apply a small initial force to lift the lid, and the gas struts should take over, smoothly raising and holding the lid in the open position. To close the lid, the user should gently push it downward, overcoming the strut's force, and it should retract smoothly.
Adjustments and Fine-Tuning: In some cases, adjustments may be necessary to fine-tune the performance of the struts. This may involve repositioning the brackets or adjusting the tension on the struts. The manufacturer recommends periodic inspection of the mounting points and ball socket connections to ensure they remain secure and tight.
Maintenance and Longevity
ARANA gas struts are designed for long-term, maintenance-free operation. However, periodic inspection and cleaning can help ensure continued optimal performance. The following maintenance recommendations are provided by the manufacturer:
Cleanliness: The strut rods should be kept clean and free from dirt, dust, or debris. If necessary, they can be wiped with a clean, damp cloth. It is important to avoid using abrasive cleaners, as these can damage the surface of the struts and reduce their lifespan.
Inspect Connections: The mounting points and ball socket connections should be periodically checked to ensure they remain secure. Any loose nuts or screws should be tightened to prevent loosening over time. This is particularly important in applications where the struts are subjected to frequent use or heavy loads.
By following these maintenance guidelines, users can help extend the lifespan of their ARANA gas struts and ensure continued reliable performance.
Real-World Applications and User Experiences
In addition to the manufacturer’s specifications and installation guidelines, real-world user experiences provide valuable insights into the practical application of the ARANA 23-inch 35 LB Gas Struts. These insights are particularly relevant in the context of automotive applications, such as the retrofitting of these struts into third-generation Mazda RX-7 models (1993–2002).
Retrofitting the Mazda RX-7
Several users in the RX-7 community have documented their experiences with retrofitting the ARANA gas struts into their vehicles. One user, for example, described the process of replacing the OEM rear hatch lift supports with aftermarket struts. The user noted that while the new supports matched the OEM lengths and fit, some modifications were required to accommodate the new hardware. This included removing the OEM brackets and making adjustments to the mounting points.
The installation process involved several steps, including removing plastic trim pieces, scuff plates, and seat belt mounting bolts. The user also noted the importance of using a “skyhook” method to hold the hatch lid in place during installation. This involved tying a rope from the hatch lid’s latch bracket to an overhead garage door hinge, allowing the lid to remain in an open position while the installation was completed.
Another user provided a detailed step-by-step guide for modifying the OEM lift supports to accommodate the new struts. This involved securing the bracket in a vice and drilling out the smaller end of the bracket using a 7/16 drill bit. The user then used a Dremel tool to carefully cut the outer edge of the metal retainer, allowing the strut to be removed with ease.
These user experiences highlight the importance of careful planning and attention to detail when retrofitting gas struts into existing systems. While the ARANA struts offer a cost-effective and durable solution, the installation process may require some modifications to ensure compatibility with the existing hardware.
