When the Ironhead Sportster first appeared in 1957, it combined high-tech four-cam OHV design with the reliability of cast iron cylinder heads. This bike was a reply to the Brit-bike challenge, and hot rodders immediately set to work matching its great looks with increased performance.

The tradition continues. We supply a range of products and services that'll make your Ironhead run with today's Sportsters.

For starters, you should consider our No Lead conversion service to save your valves from today's lower-octane, lead-free gas.

Our replacement valve springs will reduce friction; Dual Plugging will eliminate detonation you may not even be aware of,  and our Super Port Flow process will give you more horsepower per dollar—guaranteed!
