Brock’s Performance / Vity’s Design Billet Aluminum Swingarm (Red) for Harley-Davidson Touring Models (2009-2025)

When engineering a modern high-performance bagger, standard factory components quickly become the weak link in your chassis setup. The stock stamped-steel swingarm on Harley-Davidson Touring models is notorious for flexing under heavy acceleration, cornering loads, and high speeds, resulting in unstable rear-end sway or the dreaded bagger wobble. The Brock’s Performance Vity’s Design Billet Aluminum Swingarm provides an uncompromising solution for competitive performance bagger builds, aggressive street riders, and custom enthusiasts alike. Precision-machined in Italy and distributed by the sportbike and V-Twin tuning experts at Brock’s Performance, this structural masterpiece eliminates chassis deflection while giving your motorcycle an elite racing aesthetic.

The Critical Performance Advantages of Billet Aluminum Construction

The primary enemy of precise motorcycle handling is unsprung weight and torsional flex. By upgrading from the heavy factory steel assembly to the Vity’s Design billet aluminum architecture, you achieve two vital performance milestones simultaneously. First, the incredibly high structural rigidity of CNC-machined 6061-T6 aluminum ensures that your rear wheel remains perfectly perpendicular to the frame, maintaining exact tracking through high-speed sweepers and under intense torque. Second, reducing the unsprung mass allows premium aftermarket rear shocks—such as Ohlins, Legend, or Bitubo—to react with vastly superior speed and efficiency to road imperfections. This drastically improves your tire’s contact patch with the asphalt, yielding maximum mechanical grip, safer braking, and a significantly smoother ride profile.

Exquisite Italian Craftsmanship and Anodized Finish

Vity’s Design is globally renowned for producing some of the finest bespoke custom motorcycle components in the world, and this swingarm is no exception. Sculpted with aggressive, flowing lines that mirror the structural stress points of the chassis, every angle is meticulously CNC-milled to maximize strength while removing unnecessary material. The entire unit is then treated with a brilliant, highly durable red anodized coating. This chemical finish not only protects the aluminum surface from corrosion, road debris, and weathering, but it also creates a stunning visual centerpiece that commands attention on the street or at the track.

Eliminate High-Speed Bagger Flex and Stabilize Your Geometry

A flexing swingarm distorts the parallel alignment between your motor mounts, transmission casing, and rear axle. Under heavy acceleration or lateral cornering g-forces, this shifting geometry introduces unpredictability into your ride. The Vity’s Design swingarm features an ultra-stiff boxed structure that reinforces the entire rear section of your Harley-Davidson frame. By replacing the sloppy, failure-prone factory rubber bushings with tight-tolerance, industrial-grade spherical bearings, this swingarm provides a zero-play pivot motion. Your motorcycle will track truer, respond faster to rider inputs, and remain completely composed at high highway speeds.

Advanced Technical Specifications

No detail has been overlooked in the development of this ultra-premium swingarm. From the integrated brake lines routing to the beautifully engineered rear axle blocks, it is built to satisfy the demands of professional mechanics and elite builders alike.

Professional Installation and Maintenance Guide

Due to the critical nature of motorcycle rear suspension and drivetrain alignment, installation of the Brock’s Vity’s Design swingarm must be executed with precision. We highly recommend utilizing a certified factory technician or an experienced custom V-Twin technician. During setup, the primary vehicle tracking must be carefully checked using professional alignment tools. Always inspect the condition of your main swingarm pivot shaft and front/rear engine isolation mounts; replacing worn rubber mounts will unlock the absolute maximum performance out of your new billet arm. Ensure that all fasteners, particularly shock absorber mounting points and the rear axle nut, are torqued strictly according to the manufacturer specifications and factory service manuals. Periodic cleaning with mild soap and water is recommended to preserve the brilliant deep-red anodized finish.
