Notes: This is a 99mm Billet Aluminum cylinder that has a forged aluminum sleeve installed it is coated with Ceramic Nickel Bore. At 4mm over OEM bored cylinders have about a 20% failure rate. That is why we designed the Ice Cube cylinder.

The Ice Cube Cylinder is the only aftermarket cylinder available that was designed for big bore applications right from the start.

Most of the cast big bore cylinders that are out there were originally designed as stock replacement cylinders. Once the big bore movement really took off around 2005 companies decided to machine and plate them oversize to sell to the budget big bore market. Most of these cylinders have less than 1/2 of the coolant capacity of the Ice Cube. (We know because we checked them).

Water jacket capacity is not where the Ice Cube advantages stop. The Ice Cube is made from 2 extremely dense forms of aeorspace grade aluminum, billet and forged. Dense forged aluminum (the same grade as piston forgings) provides the higest level of strength and transfers heat faster than steel or even cast aluminum. These strength and heat transfer properties makes it ideal for this application where space is limited and stress is increased. The Ice Cube is also the only cylinder that has extended cylinder skirts that provide piston support at BDC for stroker cranks. This advantage alone increases piston life dramatically in stroker applications.

This kit is a good choice for the customer who is looking for the kit with the best value out there. The addition of this kit not only will raise the value of your machine but it will set you apart from the crowd as an owner that is not willing to compromise on performance. The Ice Cube Cylinder means quality and value backed by Max Power support. The Ice Cube cylinder is compatable with most stroker cranks that require a stock height cylinder. Call if you have application questions.

The Ice Cube is coated with Max Power’s Ceramic Nickel Bore coating. It is the best plating available and Max Power’s plating craftsmanship far surpasses the quality of anything else out there. (Just ask builders like Pro Circuit, Duncan Racing, ATP, Rossier Engineering, CT Racing or any of the factory teams- We plate cylinders for all of them.)

We offer this as a kit with a CP piston kit in various compression ratios. If you are looking to use your own piston we also can make you this cylinder in custom bore sizes for $995. Just call or e-mail us with your requirements.
