About This Product
Tuning your front suspension has never been easier than with this 49mm fork spring preload adjuster kit from Progressive Suspension. These black anodized adjusters replace your stock fork tube plugs and provide a full 20mm of threaded adjustment. This allows you to stiffen the front end for aggressive riding or heavy loads, or soften it up for a more relaxed cruise. The kit is sold as a set and includes a hex adjustment tool and an installation socket. It fits a wide range of models, including 2018 to 2026 Softails (excluding inverted forks), 2014 to 2026 Touring and Trike models (excluding 2023-2026 inverted forks), and 2006 to 2017 Dynas, excluding the FXDLRS.
Manufacturer part number: 31-5056.
