Sleeves

When stock cylinder walls aren’t thick enough for your target boost, big-bore or revs, sleeving is the answer. Pro-Race Engineering supplies Darton MID (Modular Integrated Deck) sleeves and other competition-grade sleeve kits — and we also offer a complete in-house block sleeving service from our Maldon workshop, including line boring, decking and combustion-chamber finishing.

Whether you’re planning a one-off race motor or a small batch of customer engines, our engineering team can specify the right sleeve material, interference fit, and machining sequence for your block and intended use. For a quote on sleeves supplied-only, supplied-and-fitted, or a full block-strengthening package, call the workshop on 01621 473023.
