Cylinder head Kubota V2403 engine

Description

PLEASE NOTE — this is the DI version only (Direct Injection). This cylinder head fits only the newer Kubota 03-series engines with direct injection and is not interchangeable with the older indirect (pre-chamber / IDI) version. Not sure which one you have? A DI engine uses thin pencil injectors and a rocker cover with 10 bolts. In doubt? Just email us your engine number and we’ll check it for you.

Brand-new cylinder head, made from high-grade castings and precision-machined for an exact OEM fit. Available in two versions — make your choice above between complete or bare.

Version 1 — Complete with valves and springs, ready to fit

This cylinder head is supplied fully assembled, including fitted valves and valve springs. No need to transfer parts or make adjustments: straight out of the box and onto the engine.

✔️ Fully assembled — valves and springs already fitted
✔️ No extra adjustment or build-up work needed
✔️ Ready to fit — saves workshop time
✔️ Lower risk of assembly errors

Version 2 — Bare (cylinder head only) with pre-fitted valve seats

This bare cylinder head is supplied with valve seats already fitted, ready to be built up with your own or new components.

✔️ Brand-new top-quality cylinder head
✔️ Valve seats already fitted
✔️ Ready for further assembly
✔️ Ideal for overhaul or custom builds where you want to reuse parts

The difference between the two versions

Choose Complete if you want a ready-to-fit head without transferring valves/springs. Choose Bare if you do the final assembly yourself or want to reuse existing components. Both versions are the same DI head — the difference is purely in what’s already fitted.
