Precision CNC-machined case spigots using Renishaw probing for perfect alignment and fitment.
This service ensures flawless cylinder-to-case alignment and true bore geometry for big bore conversions. Each set of cases is digitally mapped with a Renishaw probing system to establish exact centerlines before machining. The result is unmatched accuracy, proper deck height consistency, and perfect sealing surface alignment for your new cylinder setup.
Digitally indicated with Renishaw probe for absolute alignment and repeatability
CNC-bored spigots for precise cylinder fitment and correct register depth
Chamfered and deburred for clean gasket seating and easy installation
Machined with torque plates installed to replicate in-engine distortion
Matched to customer’s cylinder and piston dimensions for exact clearances
Result: perfectly true, concentric, and aligned case spigots — the professional standard for reliable big bore power and long-term sealing integrity.
Note: This is a send-in machining service.
Customer must ship in clean, disassembled crankcases with a pre-paid return shipping label.
If cases arrive assembled or uncleaned, additional cleaning and handling charges will apply.
Include your cylinder and piston specifications with your shipment to ensure proper bore sizing.
