Progressive Suspension 412 Series Shock - 12.5 Inch Heavy Duty Black for Harley FL Models (Part Number: 412-4076B)

The Progressive Suspension 412 Series Shock is specifically designed for Harley Davidson FL models, offering a reliable and cost-effective upgrade to your motorcycle's suspension. With a durable construction and straightforward installation, this shock enhances ride quality and handling while maintaining a sleek appearance. Its heavy-duty build makes it suitable for riders operating at or near the manufacturer's maximum load over 50% of the time, ensuring durability and consistent performance under demanding conditions.
Featuring a five-position cam style spring preload adjuster, this shock allows riders to fine-tune their suspension setup easily, providing customized comfort and handling. The black finish adds a modern, aggressive look to your bike, and the shock's design ensures compatibility with a variety of styling options, including full chrome or black covers, springs, and end caps. Made in the USA, this shock is measured center-to-center eyelet to center-to-center eyelet, guaranteeing precise fitment on your Harley.
When installing on '86-'15 XL models, some modifications may be necessary, such as adjusting or spacing the chain or belt guard to ensure proper clearance. Slight variations in length can influence steering characteristics; a longer shock can provide quicker steering while a shorter shock may result in a slower response. Before replacing OEM shocks with non-standard lengths, verify that wheel travel and clearance points—such as swingarm, axle, exhaust, and chain or belt guard—are not compromised. This ensures optimal performance and safety for your ride.
