When refreshing the cylinder heads on a 1957 to 1983 Sportster, choosing the right guide size is critical for heat transfer and stability.

It features a +.002 inch oversize outer diameter, allowing for a proper interference fit in heads where the original bores have been cleaned up or slightly enlarged. The standard non-oversize dimensions for reference are 0.5650 inch outer diameter, 0.3085 inch inner diameter, and 1.77 inch overall length. Sold individually, these guides provide the durability required to keep your vintage Sportster running strong across the long haul.
