Harley-Davidson X440 / X440 OBDII / X440T Rear Wheel Damper OEM | HDH41241-ACD-000

Replace worn rear wheel dampers with this genuine OEM rear wheel damper for Harley-Davidson X440 series motorcycles. Part number HDH41241-ACD-000 is the correct OEM replacement for riders searching for the rear wheel damper, cush damper, rear hub damper, or sprocket carrier damper on the listed X440 models.

Rear wheel dampers help absorb drivetrain shock between the sprocket carrier and rear wheel assembly. When these rubber dampers wear out, riders may notice extra play in the rear hub area, harsher driveline feel, clunking during throttle transitions, or a loose feel from the rear sprocket carrier. Replacing worn dampers helps restore tighter driveline response and smoother power transfer.

This page is written in buyer language, not factory-jargon-heavy wording. Customers rarely search only by the internal description, so this listing is optimized around the names riders actually use: rear wheel damper, cush damper, and rear hub damper.

Confirmed fitment: Harley-Davidson X440, X440 OBDII, and X440T. This SKU is not confirmed here for X440X or Hero Mavrick 440, so please do not assume it is common across all 440-family motorcycles.

This listing is for one rear wheel damper unit. Please match the old part number and your rear hub / cush drive requirement before ordering.
