Overview

Uniform hardness all the way through the steel barrel walls which allows the barrel to provide even wear while withstanding extreme cylinder temperatures and pressures.

Exhaust and intake ports are volumetrically matched to maximum output and performance.

Increased port wall thickness - eliminates problems with warping and cracking.

Computer-generated head fin configuration - deliver more uniform heat transfer and fewer "hot" spots.

Manufactured from the most advanced alloys available - exceed industry standard for strength and porosity.

+ Included with stud assembly.

Reviews

I was told upon ordering that the cylinder would come with the rings fitted and on the piston inserted in the bore. All I would need to do is pull the piston out far enough to get the new wrist pin into the connecting rod and bolt it up. The piston was in a box. The rings were not fitted to the bore and were in a box. There was no new wrist pin in the parts received. There is a rocker arm shaft but no piston wrist pin?
