Genuine Kubota Style Piston & Ring Kit – Fits V2203, V2403, V2403MDI (1G790-21112) By HQ

About This Product

Alright, so here’s the deal: this is a brand new piston assembly that’s a dead ringer for the Kubota OEM part.

It’s made by HQ, and it’s ready to get your machine purring again.

We’re talking a perfect fit for a ton of equipment—think Dynapac rollers, Bobcat loaders, and a whole slew of Kubota tractors and excavators like the L3830D, BX2670, or the KX018-4.

This specific one is the 1G790-21112 replacement, so you know you’re getting the right gear.

Let’s get into the nitty-gritty details.

The piston diameter is a solid 87mm, and the ring set is configured at 2mm, 2mm, and 4mm.

The bowl measures in at 47mm.

Everything is brand new, still in its original packaging, so you’re not getting someone else’s problem.

It’s a straight-up replacement part to get you back to work.

If you’re rebuilding a V2203 or a V2403, this is the core component you’ve been looking for.
