FAQ

Common Questions

What's the difference between this ring set (16423-21110, $44.99) and SKU 2442 (17331-21050, $19.99)?

Both are V2203 STD 87mm ring sets but for different OEM applications. SKU 2442 (17331-21050) is the common Bobcat 753/763/773 ring with specific dimensions (87 × 2.50 × 2.00 × 5.00 mm) and is sold per cylinder. This SKU 2435-2442 (16423-21110) covers V2203 IDI applications and L3830D / BX2670 / M7060D / KX018-4 / KX91-3SS / BX2660 — different ring section than the Bobcat version. Match the OEM number on your old rings or in your engine manual.

Does this include a piston?

No — ring set only. If you need a piston with new rings, that's a separate Piston + Ring Kit SKU.

How do I know if my engine needs STD or oversize rings?

Measure the cylinder bore with a bore gauge. If the bore is at or near 87mm standard and within Kubota's wear limit, STD rings are correct. If any cylinder has been bored oversize previously (0.25mm, 0.50mm), you need oversize rings — see SKU 2447 (Ring Set Oversize). Call (818) 261-3896 if you need help interpreting your measurements.

What's your return policy

We offer free returns within 30 days if the part doesn't fit or you're not satisfied. Parts must be unused and in original packaging.

Do you offer technical support?

Yes. Call (818) 261-3896 and we'll help you confirm fitment, answer installation questions, or troubleshoot issues.

How long does shipping take?

Orders ship same-day if placed before 3 PM EST. Standard delivery is 3-5 business days.
