The ZETA 50B Preload Adjuster makes suspension preload adjustment easier by replacing the stock locknut and spring seat. Its turning adjustment method eliminates the need to tap the spring retainer during setup, allowing preload changes by hand even when the component is installed on the motorcycle.
Using a band-style adjustment method associated with WP and other suspension companies, the adjuster can be locked and unlocked with a 5mm hex wrench. The ZETA ZE56-13042 fits the 2018–2022 Suzuki RM-Z450, 2019–2021 Kawasaki KX450F, and 2021 Kawasaki KX450X. Manufacturer part number: ZE56-13042. Vendor part number: ZE56-13042.
