Experience true sport performance with the Progressive 494 Series Heavy Duty Shocks designed specifically for Harley-Davidson Dyna models from 2006 to 2017. These shocks feature a high-pressure monotube construction with deflective disc damping technology, providing consistent and reliable damping performance in a variety of riding conditions. The handcrafted, dyno-tested shocks incorporate a lightweight aluminum body and a progressive rate coil spring, ensuring stability and comfort whether you're cruising city streets or tackling the race track. The adjustable rebound damping and hand-threaded preload give you fine-tuned control over your ride quality, making these shocks versatile for different terrains and rider preferences. An integrated jounce bumper with a built-in metal cup helps absorb impacts and control bottoming out for a smoother ride and increased component protection.
