New for 2016 from Progressive Suspension! These 412 Series and 430 Series Shocks are now available for the Harley-Davidson Street XG 500/750 models. Matching these shocks with Progressive's Fork Spring Kit creates a full system that will dial in your bike for optimal performance and comfort. The 412 Series Shocks, the company's most economical option, boasts a simple, durable design to improve performance over the OE stock shocks. The 430 Series Shocks provide threaded pre-load adjusters for tool-less adjustment on the go. Both models are available in lengths ranging from 12 inches to 13.5 inches. The shock absorbers come in Chrome and Contrast Cut finishes. They come in a standard or heavy spring rate for a combined rider’s weight over 250 lbs.
