How to Fit Racing Sleeve Properly, and Improve Engine Power?

Racing Sleeve Properly, and Improve Engine Power

Racing Sleeve offer protection against wear for piston rings. These are not very thing as they are supported by the engine block. Cast iron blocks don’t need sleeves are iron can resist wear, but if the cylinder gets cracked, it needs sleeving to work, and increase its output. Following, we are giving you a deep insight into that.

Racing Sleeve Properly, and Improve Engine Power

Fitting the Racing Sleeve

It doesn’t matter whether you install the sleeve on iron or aluminum block, just make sure it installed according to the dimension. Block cylinders have to be machined as round and straight for a perfect fit.  Bores have to chamfered to minimize bore distortion.

Sleeves have to be made according to tolerance for a proper fit. If the block or sleeve has variation, it distorts cylinder bore, and affects ring sealing. This compresses oil consumption. If the case is severe, it may lead to piston scuffing between the piston and wall.


Converting LS Engine to wet sleeve takes hours of hard work. This approach is adopted to convert improve performance of various different engines.

Wet Racing Sleeve can increase the output of engine without cracking issues. The problem is, dry sleeves can’t take as much heat as wet sleeves. This is why high-end nickel alloy is used with cast or ductile irons in sleeves. This configuration is used for drag racers mainly.

In case you find the after-market Racing Sleeves are not up to your needs, you can always buy custom ones. Ductile iron is a common manufacturing material, and it uses compacted graphite.

Custom part keeps the tolerance tight, this encourages customer to bid their specifications for their custom Racing Sleeve. The only issue is custom sleeves are a bit more expensive than pre-made but they do improve the overall performance of vehicles. This is why most people are happy to by the small difference in price.
