Progressive Suspension 412 Series Shock - 12.6 inch Heavy Duty Black for Harley-Davidson 412-4048B

The Progressive Suspension 412 Series Shock (Part Number: 412-4048B) is designed to enhance the ride quality and handling of Harley-Davidson models. With a length of 12.6 inches, these shocks offer a reliable upgrade over stock components, providing improved stability and comfort during highway cruising and spirited riding. Crafted with durability in mind, the shocks feature a simple yet robust design that makes them an economical choice for riders seeking to boost their motorcycle's suspension performance. They are suitable for heavy-duty applications, making them ideal for bikes often operated near their maximum load capacity. The black finish adds a sleek, understated look to your motorcycle while ensuring corrosion resistance and longevity.
The shocks come equipped with a five-position cam style spring preload adjuster, allowing riders to fine-tune their suspension setup with ease. This feature provides flexibility in adapting the ride to different loads and riding conditions, ensuring optimal comfort and handling. All shocks are measured from center of eyelet to center of eyelet, ensuring compatibility and straightforward installation. Some models are approved for road use; always refer to the latest certification for current compliance requirements. When installing on '86-'15 XL models, modifications such as spacing the chain or belt guard may be necessary to maintain proper clearance. Slightly longer shocks can alter the head angle, resulting in quicker steering, whereas shorter shocks may slow steering response. It is important to confirm that wheel travel and clearance are adequate before installation to avoid contact issues with the swingarm, exhaust, or tires. The 412 series is available in various style options, including full show-chrome or black covers, and either chrome or black springs and end caps, allowing customization to match your motorcycle's aesthetic.
