Nissan K21 & K25 Forklift Cylinder Heads & Engine Parts

Looking for a premium aftermarket replacement Nissan K21 or K25 forklift cylinder head? We supply brand-new complete heads, gasket sets, and internal engine components from premium Australian stock with rapid nationwide delivery to get your equipment back to work.

The Nissan K21 and K25 inline-four engines are industry-standard powerplants across Australian warehouses, but running constantly on dry LPG under heavy load creates extreme thermal stress. Common symptoms of a failed K21/K25 head include hard starting, loss of hydraulic or driving power, mysterious coolant consumption, or heavy bubbling in the radiator.

Why Choose Midland Cylinder Heads?

  • Australian-Assembled Quality: Our licensed technicians build and inspect every brand-new cylinder head to strict OEM specifications, with all valve depths pre-set during assembly.
  • Premium Standard-Thickness MLS Gaskets: Our kits feature high-grade, standard-thickness multi-layer steel (MLS) head gaskets engineered to handle continuous high-temperature LPG operation and ensure a perfect compression seal.
  • Included Torque Specs: Every order includes the correct tightening sequence and torque specifications for a perfect installation.
  • 12-Month Warranty: Drive with peace of mind with our 12-month, unlimited-kilometre warranty on all parts.
  • Fast Dispatch & No Core Exchange: Units are sold outright (no need to send your old head back), with fast dispatch from our Perth and Melbourne hubs to minimise business downtime.

Our Parts Summary

  • Brand New Assembled Cylinder Head: Premium replacement unit with brand-new valves and valve springs, professionally fitted and vacuum-tested.
  • Premium Head Gasket Set with Bolts: Comprehensive standard-thickness multi-layer steel (MLS) head gasket set with all required seals, O-rings, and fresh Torque-to-Yield (TTY) stretch bolts.
