The rings are made from a high-temperature, low-friction material that ensures consistent sealing performance throughout the entire RPM range.
Another key component of this kit is the set of high-performance, billet aluminum cylinder heads. These heads offer improved cooling capabilities, thanks to their large, high-flow intake and exhaust ports. They also feature advanced combustion chamber designs that provide improved air/fuel mixture and more complete combustion, resulting in increased power output and improved fuel efficiency.
The WISCO MN/XC2Y Top End Kit is also designed to be easy to install. The pistons come with pre-gapped, low-friction rings and ring compressors, making the ring installation process quick and straightforward. The cylinder heads come fully machined and ready to install, requiring only minimal assembly.
