Dayton, Ohio based Brock's Performance is best known for sportbike components - and swingarms in particular - but, as with carbon wheels and other components, it also offers high-end custom and performance Harley parts.
Leveraging one of its specialties, Brock's has announced a new line of swingarms designed for Baggers, Dynas and FXRs.
Manufactured from 6061-T6 aluminum, custom-shaped into rectangular tubes through an extrusion process, resulting in a high-strength, reduced weight hollow structure. These Brock's swingarms are said to be just as strong as a similar swingarm machined from a solid billet of aluminum.
"Mounted to pro-level drag race bikes, these swingarms stand up to launch after launch. Each one comes with a hollow, Chromoly axle (1", 25 mm or 28 mm diameter) and all the hardware necessary for installation, including spherical pivot bearings lined with PTFE - so no service is needed."
Brock's flexible design allows for a wheelbase of up to three inches longer than stock. Multiple shock mount locations (three positions) make it easy to lower the rear up to two inches (all versions) or raise the back up by up to two inches (West Coast Bagger version).
"A combination of innovative design, quality manufacturing and thoughtful packaging means that Brock's Touring and Dyna swingarms are 100% bolt-on, using your OEM rear wheel and pulley, or your favorite aftermarket replacement rear wheel.
"We developed these swingarms as a result of our Pro Street (700 hp/350 ft-lbs) racing experience. We weld them in a precision fixture for an ultra-straight, consistent fit every time. They are designed to accept a stock wheel, spacers and caliper or the aftermarket components of your choice (custom fabrication required on FXR spacing)."
The swingarms ship with Teflon encapsulated spherical bearings pre-installed. They will accept a 200 tire mounted on a 6.75 inch rim, with a chain conversion, and are available for Baggers from '09-'20, FXRs from '82-'00 and Dynas from '00-'17.
