How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

Description

Fleece Performance

The Fleece Performance Freedom Series Cummins Performance Cylinder Heads are engineered for high horsepower diesel applications where strength and reliability are critical. Each cylinder head is manufactured in Fleece Performance’s state of the art cylinder head machine shop and is guaranteed to meet or exceed factory specifications.

Every head is fully inspected, pressure tested, decked, painted, and shipped ready for installation. The addition of 11 screw-in freeze plugs eliminates the risk of coolant leaks under the valve cover, a common failure point on factory cylinder heads.

Whether the application is sled pulling, drag racing, or heavy towing, the Fleece Performance 5.9L Cummins Performance Cylinder Heads deliver the airflow and durability needed for serious power. These heads are rated to support up to 1,100 horsepower.
