Important Service Details – Please Read Before Purchasing
Pricing Note: Cylinders over 90mm in diameter are $120 per bore.
You must send your oversize piston along with the bare cylinder (“jug”). Be sure to select a large enough piston to clean up existing bore damage.
We are not responsible if the cylinder cannot be properly bored due to an undersized piston being provided.
Boring range: 1.5" to 6" in diameter.
Compatible Cylinder Types
This service is for cast iron sleeve cylinders only.
Do not send Nikasil cylinders – they cannot be bored oversize. For damaged Nikasil cylinders, we offer a separate resleeving service. Contact us directly if needed.
