Hellwig 7320 Details

Hellwig Big Wig

Hellwig Logo

Big Wig sway bars are a more heavy duty version of the standard Hellwig sway bars. Since they feature a thicker diameter, these sway bars offer better vehicle control by reducing body roll while taking a corner. By keeping the weight on all four tires while cornering, these sway bars produce a greater amount of traction, making them an exceptional choice among sway bar products.

Big Wig sway bars are a perfect fit for GM, Chevy, Ford and Dodge Super Duty and Heavy Duty trucks.

Hellwig Big Wig rear sway bars are load specific, meaning that they are great for truck campers, heavy haulers and heavy tow applications, because they are made specifically for vehicles with an exceptionally high center of gravity. Vehicles with a high center of gravity have more stress on their suspension while negotiating a turn.

This added stress makes controlling the vehicle more difficult. Combat this issue with the Hellwig Big Wig. Due to it's larger diameter and increased surface, the Hellwig Big Wig rear sway bars provides over 20% more stability by increasing the roll stiffness of the suspension. This added stability creates better traction and handling, giving you increased safety and comfort while cornering.

Creating a firmer suspension is important but a sway bar has to be able to withstand the stress and strain created by the additional weight of the camper. Again the extra wide diameter adds to durability of the Big Wig. Further improving the durability of the Big Wig is the included mounting hardware. This hardware has been stepped up in size to give this sway bar the resistance to vibration and shock that it needs to get the job done.

Hellwig Sway Bars are made in the USA and have a lifetime guarantee.

Customer Q&A - Hellwig 7320

What is the difference between the 7321 and the 7320 sway bar ?, and don't tell ones for the 4 wheel drive. Tell me the difference in the length in the adjustable links, between the 2 sway bar kits. Thanks you

The difference in the two kits is the length of the links, The 7320 has 11"-14" adjustable links and the 7321 has 8" - 11" adjustable links.

Are there any fitment issues with this sway bar? For example, with the factory spare tire, factory exhaust, etc.? I've heard from people who have replaced sway bars on various makes and models that have had to make some modifications and I'm just wondering if there are any that need to be made with this bar on a stock 2018 F350 diesel with 8' bed. Thanks

This sway bar should have no fitment issues. There is ample space for these and on a stock truck, there should be no need to make any modifications. There is some adjustment for positioning so it may take some tweaking to get everything to fit correctly.
