Cylinder Sleeves and Liners for Supercars and Performance Cars

Sleeves are what let a block carry more than it was designed to. They restore a damaged bore that would otherwise scrap an expensive casting, they allow a larger bore than the original material would support, and in closed deck form they stiffen the top of the block so the cylinders stop moving under high boost. This is specialist territory bought by engine builders and workshops preparing supercar and performance car engines for serious output, since sleeving is machine shop work with no shortcuts. We supply cylinder sleeves and liners for supercars and performance cars and deliver across Dubai and the UAE, to India, and worldwide.

What This Collection Covers

• Ductile iron dry sleeves: press fit sleeves for repairing or strengthening a standard block.
• Wet liners: liners in direct contact with coolant for engines designed around that arrangement.
• Big bore sleeves: thicker or larger sleeves that allow a bore size the original casting could not take.
• Closed deck sleeve kits: kits used to convert an open deck block to a closed or semi closed deck arrangement.
• Flanged and non flanged options: top flange designs to suit different retention methods.
• Single sleeves and full sets: individual sleeves for a repair or complete sets for a full block build.
• Sleeve related sealing hardware: O rings and small sealing items associated with liner installation.

Why It Matters

Open deck blocks are the limiting factor on many high output builds, because at high cylinder pressure the tops of the bores can move enough to disturb the head gasket seal, and once that starts the engine will keep failing gaskets no matter what else is changed. A closed deck sleeve kit ties the cylinders back to the outer wall and removes that movement. Sleeving is also the only way to save a block with a scored or cracked bore, and on a big bore build it provides the wall thickness the standard casting simply does not have.

How to Choose the Right Sleeves

This is a decision to make with your machine shop before ordering, because the bore, the interference fit, the height and the retention method all depend on how they intend to machine the block. Repairing a single damaged cylinder is a very different job from a full closed deck conversion, and the sleeve specification follows from that choice. Installation and final honing is machine shop work and we supply the sleeves to their specification. Send us the car, the year, the exact variant, the target bore and the sleeve type they have asked for. WhatsApp us on +971 50 308 5760 or send us an inquiry and we will source them.

Shipping and Availability

We deliver cylinder sleeves across Dubai and the UAE, to India, and worldwide. Sleeves are normally sourced to order in the size and configuration required, and full kits can take longer than single sleeves. The lead time is confirmed before payment so the block can be booked into the machine shop for the right week.
