Harley-Davidson X440 / X440 OBDII / X440T Chain Slider OEM | HDH52170-ACJ-000

Protect the swingarm and guide the chain correctly with this genuine OEM chain slider for Harley-Davidson X440 series motorcycles. Part number HDH52170-ACJ-000 is listed as SLIDER CHAIN. In buyer language, riders are more likely to search for this as the chain slider, swingarm chain slider, chain guide slider, or chain rubbing pad.

This part sits along the chain path and helps reduce direct rubbing between the drive chain and the swingarm or guide area. When the old slider wears down, cracks, breaks, or gets chewed by a loose or badly adjusted chain, it can allow unwanted chain contact, extra noise, faster wear on nearby parts, and an untidy drivetrain setup. Replacing it with the correct OEM chain slider helps restore proper chain guidance and protection.

This page is written in customer-first language so buyers can find the part using the names they actually search. Instead of relying only on the factory term, it naturally includes search phrases like chain slider, chain guide, swingarm slider, and chain pad.

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 chain slider only. It is not the chain, not the sprocket, and not a complete chain kit. Please match the old part number and exact requirement before ordering.
