Kuryakyn Cylinder Base Timing Hole Cover For Harley-Davidson Softail (2007–2017)
Seamless Chrome Transition & Custom Engine Base Detail for Softail Twin Cam V-Twins
Clean up the left side of your Harley-Davidson engine bay and mask unfinished crankcase castings with the Kuryakyn Cylinder Base Timing Hole Cover. Specially contoured for 2007 through 2017 Harley-Davidson Softail models powered by Twin Cam 96, 103, and 110 engines, this custom dress-up piece bridges the gap between the primary case, inner crankcase, and lower cylinder fins.
Finished in Kuryakyn’s show-quality mirror chrome, this sleek accent cover transforms a dark, unfinished utilitarian section of the engine block into a smooth, continuous polished surface. It conceals exposed bolt heads, rough casting lines, and the crankcase timing plug region, delivering a pristine visual flow that perfectly complements outer primary covers, transmission shrouds, and chrome horn covers.

Design Highlights & Custom Engine Aesthetics
### Concealing Unfinished Softail Engine Castings
Late-model Twin Cam 96, 103, and 110 Softail engine cases feature exposed crankcase timing plugs and rough aluminum casting seams where the cylinders bolt to the block. The Kuryakyn Cylinder Base Cover acts as a smooth architectural shroud, draping over these raw areas to create a polished, custom-built look across the lower left side of the engine.
### Engineered for Heat & Vibration Resistance
Designed specifically to endure the extreme operating temperatures generated by large-displacement air-cooled V-Twins, this cover will not tarnish, discolor, or peel. Its precise, vibration-isolated fit prevents annoying rattles, keeping your powertrain looking smooth and running quietly down the highway.
