905283 Replacement XL 900cc cast piston. +.020"

This cast replacement piston is a dependable choice for refreshing a classic Ironhead Sportster. Specifically engineered for 1957 to 1971 XL900 models, this +.020" oversize piston maintains the factory 9:1 compression ratio, making it perfect for a standard stock rebuild. The package includes the wristpin and wristpin clips, but please note that piston rings must be purchased separately. As a mechanic, I always recommend verifying component suitability and clearances before installation. Proper break-in procedures are essential for any overhauled engine to ensure long-term reliability. This part is a direct replacement for OEM 905283 and helps bring that vintage 900cc motor back to life.
