A Closer Look at the Hellwig Big Wig
For truck owners and RV enthusiasts seeking enhanced stability, improved load-carrying capacity, and a more comfortable ride, aftermarket air suspension systems offer a compelling upgrade. Among the leading manufacturers in this segment, Hellwig stands out with its reputation for quality engineering and durable products. One of their flagship offerings, the Hellwig Big Wig air suspension kit, promises to transform the handling and towing characteristics of your vehicle. This comprehensive report details the installation process of the Big Wig system on a [Year] [Make] [Model] pickup truck, followed by a detailed performance review, providing valuable insights for potential buyers. Our goal with this installation was to mitigate the substantial sag experienced when towing our [Type of Trailer] and to improve overall stability on long trips.
The Hellwig Big Wig air suspension kit is designed to provide significant load-leveling capabilities, effectively counteracting the effects of heavy loads on your vehicle’s suspension. The heart of the system lies in its robust air springs, constructed from high-strength rubber compounds and designed to withstand substantial pressure and repeated flexing. These air springs are significantly larger than those found in many competitor kits, allowing for a greater volume of air and, consequently, a higher load-carrying capacity.
The kit also includes heavy-duty mounting brackets, meticulously engineered from high-grade steel for exceptional strength and durability. These brackets are designed to integrate seamlessly with the vehicle’s existing suspension components, ensuring a secure and reliable installation. The quality of the brackets is immediately apparent – they are thick, well-welded, and powder-coated for corrosion resistance, inspiring confidence in their long-term performance.
High-quality air lines and fittings are essential for a reliable air suspension system, and Hellwig doesn’t cut corners in this area. The kit includes durable air lines that are resistant to punctures and abrasions, along with brass fittings that provide a tight, leak-free seal. While a basic kit provides manual inflation, offering the possibility of adjusting each spring individually, Hellwig offers optional accessories such as onboard air compressors and in-cab controls, adding convenience and allowing for on-the-fly adjustments. The Big Wig system differs from some other air suspension kits due to its focus on heavy-duty applications and its larger air spring size, which translates to a greater load-carrying capacity and potentially better ride quality under heavy loads.
Diving Into the Installation Procedure
The installation of the Hellwig Big Wig kit is generally considered a moderately challenging project, best suited for individuals with some mechanical experience and a well-equipped garage. However, with patience and attention to detail, it can be successfully tackled by a competent do-it-yourselfer.
Before beginning the installation, it’s crucial to thoroughly read the instructions provided by Hellwig. This will help you familiarize yourself with the components and the steps involved. Gather all the necessary tools, including a jack, jack stands, sockets, wrenches, torque wrench, drill (for some applications), and a cutting tool for the air lines. Safety glasses are a must!
Preparing the Vehicle
Begin by safely raising the vehicle and supporting it with jack stands. Ensure the vehicle is stable before proceeding. Disconnect the battery’s negative terminal to prevent any electrical issues.
Removing Existing Components
Depending on the vehicle, you may need to remove the factory jounce bumpers or other suspension components to make room for the Big Wig air springs. Follow the instructions carefully for your specific vehicle model.
Installing the Mounting Brackets
The mounting brackets are typically installed on the vehicle’s frame and axle. Securely bolt the brackets in place using the provided hardware, ensuring they are properly aligned and torqued to the specified values. This is a critical step, as the brackets provide the foundation for the entire system.
Attaching the Air Springs
Position the air springs onto the mounting brackets and secure them with the appropriate hardware. Ensure the air springs are properly seated and aligned.
Routing the Air Lines
Carefully route the air lines from the air springs to the desired inflation points. Avoid sharp bends or kinks in the air lines, and secure them with zip ties or clamps to prevent them from rubbing against other components. Careful planning is key here for a clean and professional installation.
Connecting the Air Fittings
Connect the air fittings to the air springs and the inflation valves. Ensure the fittings are tightened securely to prevent leaks. Use thread sealant on the fittings to ensure a tight, leak-free connection.
Testing for Leaks
Inflate the air springs to a low pressure (e.g., 20 PSI) and check for leaks using a soapy water solution. If you find any leaks, tighten the fittings or replace the air lines as needed.
Optional Compressor Installation
If you purchased an optional onboard air compressor, follow the manufacturer’s instructions to install it. This typically involves mounting the compressor, wiring it to the vehicle’s electrical system, and connecting the air lines.
Final Inspection
Once the installation is complete, double-check all connections and ensure that all components are securely fastened. Lower the vehicle and test the air suspension system by inflating and deflating the air springs.

Performance Evaluation and Observations
With the Hellwig Big Wig air suspension system installed, the transformation in the vehicle’s handling and ride quality was immediately noticeable.
Unloaded Ride Quality
Even without a load, the Big Wig system improved the ride quality. The suspension felt more controlled, and the vehicle absorbed bumps and imperfections in the road more effectively. This is likely due to the larger air springs providing a more progressive spring rate.
Towing Performance
The most significant improvement was observed when towing our [Type of Trailer]. Before the installation, the vehicle experienced significant sag, causing the headlights to point upwards and reducing steering control. With the Big Wig system inflated to the recommended pressure, the vehicle sat level, and the handling was dramatically improved. Steering felt more precise, and the vehicle tracked straight and true, even in windy conditions. The reduction in sag also improved visibility and reduced driver fatigue.
Handling Improvements
The Big Wig system also enhanced the vehicle’s handling in corners. Body roll was noticeably reduced, and the vehicle felt more stable and planted. This is particularly beneficial when towing a trailer, as it reduces the risk of sway and improves overall safety.
Air Pressure Adjustments
Experimenting with different air pressure settings allowed us to fine-tune the ride quality and handling to suit various load conditions. Higher air pressures provided greater load-carrying capacity and reduced sag, while lower air pressures offered a softer ride.
The kit’s ability to maintain a level ride height, even under heavy loads, is impressive. The difference between the stock setup and the Big Wig system is night and day, particularly when towing. The improved stability and control instill confidence and make towing a much more enjoyable experience.
Considering the Long Term
While the installation was relatively recent, we anticipate the Hellwig Big Wig kit to provide years of reliable service. The quality of the components is evident, and the robust construction suggests excellent durability.
