Spacer Plates
CTP’s new replacement engine block plates are designed to offer precise fit and durability during engine rebuilds. Replacing the engine block plate is crucial to ensure the correct liner projection, which is vital for maintaining optimal engine compression and performance. Accurate liner projection ensures proper sealing of the combustion chamber, preventing potential issues such as compression leaks, oil leaks, reduced engine efficiency, and premature wear. By using high-quality replacement plates, like those from CTP, mechanics can achieve the exact specifications required for reliable and long-lasting engine rebuilds.

CTP has many new spacer plates available in stock.
