Aftermarket Harley-Davidson chopper parts and custom fabrication define Loud House Customs in Santee, where a Magnolia Avenue workshop at suite 132 produces one-of-a-kind and limited-run components for vintage American V-twins. The in-house fabricator mills fender brackets, axle-mount license-plate assemblies, and billet hardware from steel and aluminum stock at the 8733 Magnolia complex, which also houses automotive glazing specialist Apex Auto Glass. The product line targets vintage Harley engine families spanning Knucklehead, Panhead, Shovelhead, Evo Big Twin, Ironhead, and Evo Sportster platforms, with a global online catalog shipping alongside walk-in retail. Custom seat and upholstery coordination for completed chopper builds routes through East County craftspeople, including Bernies Auto Upholstery on Woodside Avenue for hand-stitched saddle work. The signature Phantom II side-mount assembly combines a license-plate bracket and integrated tail light on a single 3/4-inch axle sleeve, eliminating separate mounting hardware for a clean low-profile chopper silhouette.
