JAK’s Dominator C15 ACERT 435–550 HP Rebuild Package

JAK’s Dominator — C15 ACERT 435–550 HP

Build your C15 ACERT around an Excel by PAI inframe kit and a loaded head with Inconel intake and exhaust valves. The Dominator package includes E-series oil and water pumps, head bolts and exhaust hardware. Keep serviceable injectors or add six JAK's flow-matched 10R1273 injectors.

Inframe and loaded head are required. The starting configuration excludes injectors, the optional spacer plate and paid protection.

Package contents

  • One selected PAI inframe
  • One selected loaded head
  • 1 × Oil pump — 341312E
  • 1 × Water pump — 381809E
  • 1 × Head bolt kit — 340097
  • 1 × Exhaust manifold hardware — 340098

Stage 6 replaces the base head and includes one fire-ring gasket. No additional gasket charge is added.

Application

Original on-highway BXS / MXS / NXS 435–550 HP. Factory 600–625, SDP and non-ACERT use separate configurations.

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.
