Replace a worn or leaking front shocker oil seal with this genuine OEM oil seal for Harley-Davidson X440 series motorcycles. Part number HDH91255-RAA-000 is shown as SEAL OIL. In normal buyer language, this is best understood as a front shocker oil seal, front suspension oil seal, or front fork oil seal style sealing component for the listed X440 models.
SOLD INDIVIDUALLY
This is a small but important sealing component used in the front suspension setup. Buyers usually look for this part when there is oil seepage, visible leakage around the front suspension area, reduced damping feel, or while rebuilding and servicing the front shock / fork assembly with the correct OEM sealing part. Replacing a worn oil seal helps maintain cleaner sealing and supports proper front suspension function.
This page is written in buyer-friendly language so customers can find the part using the terms they actually search, such as front shocker oil seal, front suspension oil seal, and front fork oil seal, rather than only the factory wording.
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 shared across all 440-family motorcycles.
This listing is for one oil seal only. It is not a complete front shocker, not a full fork assembly, and not a full suspension rebuild kit unless separately stated. Please match the old part number and exact requirement before ordering.
