The Classic Volkswagen front suspension features a beam assembly that contains internal torsion slats, providing the vehicle with its suspension. In its original format, this system works well for classic vehicles, offering a vintage look and feel. However, this design has its limitations.

A common upgrade for Classic Volkswagens is a disc brake upgrade. This makes sense; we all want enhanced safety, and it's essential. To achieve this added safety, the caliper and rotor must be larger to effectively slow down a vehicle that tends to go faster than it should. This upgrade results in increased width in the vehicle's track, making the drivetrain wider. Depending on the vendor and the bolt or lug pattern chosen, the track width can increase by anywhere from zero to 1.5 inches (38 mm) with this upgrade.

Another standard improvement is the addition of a dropped spindle. For the Beetle and Ghia models, drop spindles add a total of ¾ inch (19 mm) to the overall track, or ⅜ inch (9.5 mm) on each side.

Many enthusiasts also opt to install a new set of wheels on their Classic Volkswagen. This upgrade can further alter the track width, as wheels come in various offsets and widths, allowing for either an increase or decrease in track width.

These three common upgrades can significantly change the vehicle's track width, which means that a narrowed beam may need to be purchased to return the wheels to OEM specifications or to achieve a specific look or stance. However, it's important to note that reducing the width without incorporating components that add track can greatly impact the driving experience. While a narrower stance might look appealing, it may not offer an enjoyable driving experience, so keep that in mind.

Since 2007, Airkewld has been manufacturing the Ultimate Beam, crafted from high-quality American steel. The professionals at Airkewld have built over 23,000 beams in the past 16 years. If you are considering a suspension upgrade for your Classic Volkswagen, the experts at Airkewld are knowledgeable and can guide you in the right direction, even if that doesn’t mean opting for a narrowed beam.

There are three options available to achieve your desired outcome:
1. Order and install an Ultimate Beam narrowed to the necessary specifications for your intended stance or fitment.
2. Order a PRObuilt Complete Lowering Kit, which includes all the parts needed to achieve your desired stance or fitment, along with an Ultimate Beam.
3. Order a spindle-to-spindle PRObuilt Beam from the team at Airkewld, who specialize in Volkswagen drive-trains. This option also includes the Ultimate Beam.
