Application
6NZ / 9NZ, original 435–550 HP. Piston construction and service sizes are matched to your engine. One-piece piston conversions are quoted separately.
Match engine serial, arrangement, installed components and service sizes before shipment. Different engine applications are not interchangeable upgrades.
Freight and cores
Included standard outbound freight covers lower-48 commercial-dock delivery. Residential, liftgate and other accessorials require a separate quote. Injector core obligations are separate from merchandise and tax. Deferred core handling requires final return and payment authorization paperwork; selecting a variant does not authorize a later card charge.
Included coverage
Selected heads have one-year included coverage and no core. Inframe and injector coverage varies by exact part and supplier terms. Paid Protection Plus is not currently available for online purchase. No whole-engine guarantee is offered.
Machining, installation labor, fluids, filters and unlisted repairs are excluded. Reference photos may include optional parts. The confirmed selected bill of materials controls what is supplied.
Ordering and delivery
Available to order while the selected cylinder head remains in stock. Other selected package components are sourced to order. JAK's confirms the engine configuration and delivery timing before dispatch. No same-day shipment is promised.
