Really happy with the product. Took a while to get my order but they were out of the spark plug cables I ordered. I had to email and inquire what the deal was. They were super helpful once I initiated communication. Would have been cool to get some swag or something since they took so long. But the relocator is great. I really love it. And they responded promptly once I reached out to them. Their customer service is truly fantastic.

Product Information
The Carbon Caliper Duct is engineered specifically for Harley-Davidson Sportsters to address heat buildup at the front brake caliper.
Because most Sportsters rely on a single front caliper to stop a relatively heavy motorcycle, excessive heat can develop during aggressive riding or prolonged braking.
This duct captures airflow from the front of the bike and channels it directly toward the caliper and rotor using internal diverters. Lower operating temperatures help maintain consistent braking performance, reduce fade, and extend the service life of pads, rotors, seals, and brake fluid.
Constructed from carbon fiber and steel with a matte black finish, the duct follows the fork leg for an OEM-style appearance and installs in minutes using factory mounting points.

What Our Customers Say
I had some questions on some bars, so I DMd them on Instagram. The dude I talked to was super helpful. I purchased the shirt because of his response. I’ll rep the brand due to the customer service.
Precision-machined and bolt-on perfect. Took 30 minutes to install and the difference is night and day.
Customer support answered my DMs within an hour. Shipping was on point, packaging was premium.
