One of the most reassuring aspects of this sway bar kit is its construction. ADDCO uses high-grade steel combined with a durable black powder-coated finish, which not only provides strength but also protects against rust and corrosion. This is crucial for older vehicles like the ’65-’79 Ford trucks that might be exposed to the elements or occasional off-road use. The powder coating ensures the sway bar maintains its integrity and appearance over time, reducing maintenance concerns. For me, this means investing in a product that will last and continue to perform well even in less-than-ideal conditions.

The fact that these bushings provide an exact fit means I can expect a precise and responsive feel when driving, which is a big plus for anyone looking to enhance their truck’s handling dynamics without sacrificing comfort. Compared to stock rubber bushings, urethane offers better longevity and performance, making this kit a smart upgrade.

The bar diameter of 1.000” (1 inch) is another thoughtful detail that strikes a good balance between stiffness and ride quality. It’s stiff enough to reduce body lean significantly but not so aggressive that it makes daily driving uncomfortable. For me, this means I can enjoy better control and confidence in turns, whether I’m cruising around town or taking my truck on winding roads. This size is also compatible with the front position on the specified models, ensuring that the sway bar works in harmony with the truck’s suspension setup.

Lastly, the ADDCO Forever Warranty adds a layer of trust and assurance that I really appreciate.
