Frequently Asked Questions

Will this cam work with my stock valve springs?

Yes — the 514 is engineered to work with factory valve springs, so you don't need additional valve-train upgrades.

What's the peak power band for this cam?

Peak performance occurs between 1500 and 5000 rpm, optimized for cruising torque rather than high-rpm horsepower.

Is this better for heavier bikes?

Yes — low-rpm pulling power and stock compression compatibility make it ideal for larger, heavier Harley cruisers.

Do I need to retune my ECM?

Rocket recommends pairing this cam with a free-flow air cleaner and performance exhaust for best results. ECM tuning may vary by setup.
