When it comes to heavy-duty trucks and vehicles that frequently tow or haul heavy loads, a robust suspension system is paramount. That’s where the Hellwig Big Wig air suspension kit comes into play. Designed to provide superior load leveling and ride comfort, the Big Wig promises to transform the driving experience. This article isn’t just about bolting on some new parts; it’s a comprehensive Hellwig Big Wig installation report and performance review, detailing the installation process, challenges encountered, and, most importantly, an in-depth assessment of its real-world performance. The goal here is to provide potential buyers with a clear and honest picture of what to expect when upgrading to the Hellwig Big Wig. Having spent countless hours wrenching on vehicles, I was eager to see if this kit lived up to the hype.
The Big Wig Kit: Unboxing and Initial Impressions
The arrival of the Big Wig kit was met with anticipation. Upon unboxing, the first thing that struck me was the sheer size and robust construction of the components. The kit included everything needed for a complete installation (for my particular vehicle, a 2018 Ford F-250): the air springs themselves, heavy-duty mounting brackets, all necessary hardware (bolts, washers, nuts), air lines, fittings, and detailed instructions.
The quality of the materials was immediately apparent. The air springs were thick and appeared incredibly durable. The brackets were made from heavy-gauge steel and powder-coated for corrosion resistance. Even the smaller components, such as the fittings and air lines, felt well-made and of high quality. This initial assessment suggested that Hellwig wasn’t cutting any corners, a promising start to this Hellwig Big Wig installation report. The weight of the kit was substantial, further reinforcing the impression of a heavy-duty, well-engineered product.
Installation Process: A Step-by-Step Guide
Before diving into the installation, it’s crucial to gather the necessary tools. You’ll need a good socket set (both metric and standard), wrenches, a torque wrench, a jack and jack stands, a drill with various drill bits, a tubing cutter or sharp knife for the air lines, safety glasses, and work gloves. A penetrating oil spray is also highly recommended for loosening stubborn bolts.
The installation process, while relatively straightforward, requires patience and attention to detail. I would estimate about six to eight hours for a typical DIYer. Always consult the specific instructions included with your kit, as variations may exist depending on your vehicle.
First, the existing suspension components needed to be removed. This involved safely lifting the truck, securing it on jack stands, and disconnecting the factory jounce bumpers and any related hardware. Penetrating oil proved invaluable here, as some bolts were quite stubborn.
Next, the Big Wig mounting brackets were installed. These brackets attach to the truck’s frame and axle and provide a secure base for the air springs. Proper alignment of the brackets is critical for optimal performance. The instructions were clear on this point, and I took my time to ensure everything was perfectly aligned before tightening the bolts. Torque specifications were clearly provided in the instructions, and it’s essential to adhere to these to prevent component failure.
With the brackets in place, the air springs were installed. They bolted directly to the brackets, and the process was relatively simple. The instructions included specific torque values for these bolts as well.
Routing the air lines was the next step. I opted to run the lines to the rear of the truck near the license plate, where I planned to install the inflation valves. Careful routing is essential to prevent the lines from being pinched, kinked, or exposed to excessive heat. Zip ties were used liberally to secure the lines to existing frame members.
Wiring the system isn’t needed in this manual inflation setup. However, for those opting for an onboard air compressor, wiring is required. Always consult the wiring diagram provided and use proper crimping techniques to ensure reliable connections.
One challenge I encountered was the limited space around the axle. Getting a wrench on some of the bolts was a bit tight, but with some patience and creative tool use, I was able to overcome this. A tip for future installers: consider using a ratcheting wrench or a swivel socket to access these tight spots.
Post-Installation Checks and Adjustments
With the Big Wig kit fully installed, it was time to perform some essential post-installation checks. The first and most crucial step was leak testing. Using a spray bottle filled with soapy water, I sprayed all the fittings and air line connections, looking for bubbles. Fortunately, there were no leaks to be found, a testament to the quality of the fittings and the care taken during installation.
Next, I adjusted the air pressure in the springs. The Big Wig kit provides a recommended air pressure range. I started with the minimum pressure and gradually increased it until the truck sat level. Remember never to exceed the maximum rated pressure of the air springs.
An alignment check is recommended after any significant suspension modification. While the Big Wig kit didn’t drastically alter the suspension geometry, it’s always a good idea to have the alignment checked to ensure proper tire wear and handling.
The initial test drive was promising. The ride felt noticeably smoother, and the truck sat level, even with a moderate load in the bed. It was time to put the Big Wig to the real test.
Performance Review: The Rubber Meets the Road
This is where the Hellwig Big Wig installation report transitions into a crucial performance review. The difference the Big Wig made was immediately noticeable.
Ride Comfort
The ride comfort was significantly improved, especially when unloaded. The truck no longer felt as harsh over bumps and potholes. It absorbed imperfections in the road more effectively, resulting in a smoother, more comfortable ride. When loaded, the difference was even more pronounced. The air springs effectively cushioned the load, preventing the truck from sagging and maintaining a level ride height.
Load Leveling
This is where the Big Wig truly shined. With a heavy load in the bed, the truck typically would sag significantly. However, with the Big Wig inflated to the appropriate pressure, the truck remained perfectly level. This not only improved the ride quality but also enhanced safety by maintaining proper headlight alignment and preventing the rear of the truck from dragging. Before and after photos clearly illustrate the dramatic difference the Big Wig makes in load leveling.
Stability and Handling
The Big Wig also improved the truck’s stability and handling, particularly when towing. The reduced body roll and sway made the truck feel more planted and controlled, especially in windy conditions. Cornering was also noticeably improved, with less lean and more predictable handling. This added a significant degree of confidence behind the wheel.
Towing Performance
Towing a trailer with the Big Wig installed was a game-changer. The truck felt more stable and controlled, and the ride was noticeably smoother. Braking performance also seemed to improve, as the truck remained more level under hard braking. The Big Wig instilled a sense of confidence that was lacking with the stock suspension.
Long-Term Durability
While I haven’t had the Big Wig installed for an extended period, the quality of the components suggests that it will be a durable and reliable upgrade. The heavy-duty construction and corrosion-resistant finish should withstand the rigors of daily use. I’ll continue to monitor its performance over time and update this review if any issues arise.
Conclusion: A Worthwhile Investment
The Hellwig Big Wig installation report ultimately leads to one conclusion: this is a worthwhile investment for anyone who frequently tows or hauls heavy loads. The improved ride comfort, load leveling, stability, and handling make a significant difference in the driving experience. The installation process is relatively straightforward, although patience and attention to detail are essential. The quality of the components is top-notch, and the performance is outstanding.
If you’re looking to upgrade your truck’s suspension and improve its load-carrying capacity, the Hellwig Big Wig air suspension kit is definitely worth considering. It delivers on its promises and provides a noticeable improvement in both ride comfort and handling. This is a product that truly enhances the functionality and enjoyment of your vehicle.
