Progressive Suspension 412 Series Shock - 11.5 inch Heavy Duty Black for Harley FL Models - Part #412-4075B

412 Series Shock - 11.5" - Heavy Duty - Black - FL

The Progressive Suspension 412 Series Shock, designed specifically for Harley FL models, offers a reliable and cost-effective upgrade to your motorcycle's suspension system. Featuring a simple yet durable design, these shocks enhance ride comfort and stability by improving handling performance. The 11.5-inch length provides a balanced stance and is ideal for riders seeking improved responsiveness and control on various terrains. Built in the USA, the shocks are constructed with high-quality materials to withstand heavy-duty applications, making them suitable for bikes operated near their maximum load capacity most of the time. The black finish adds a sleek and modern aesthetic that complements Harley's classic styling.
The 412 Series shocks include a five-position cam-style spring preload adjuster, allowing you to easily customize the ride height and firmness to match your preferences and riding conditions. This feature ensures optimal comfort whether you're cruising city streets or tackling rougher trails. When installing these shocks on '86-'15 XL models, some modifications or spacing of the chain or belt guard may be necessary to ensure proper clearance and avoid contact issues. It's also important to verify that your wheel travel can accommodate shocks of this length without interfering with components such as the swingarm, exhaust, or tires. Slight adjustments in shock length can influence steering characteristics; a longer shock may provide quicker steering, while a shorter one could result in a more relaxed feel. Heavy-duty applications are recommended if your motorcycle regularly operates under maximum load conditions, ensuring durability and consistent performance.
These shocks are available with various styling options, including full show-chrome or black covers, and either chrome or black springs and end caps, allowing you to customize the look to match your bike's aesthetic. Please consult the most recent certification to confirm road-legal status, as some models may require additional approval. Designed for straightforward installation and tailored for Harley riders seeking performance and durability, the Progressive Suspension 412 Series Shock is an excellent upgrade for enhancing your motorcycle's suspension system.
