| 300 HP OMC Pistons | |||||||
|
Wiseco forged pistons are superior in strength due to the inherent nature of both the aluminum alloy and the forging extrusion manufacturing process. |
|||||||
| A PRO Piston is made of the highest quality alloys. Pro Pistons are made from high silicon aluminum alloy and meets or exceeds oem specifications. The Pro pistons are our most economical piston line. | |||||||
| The Pro-V Piston is made of the same alloys as the pro piston adding a gray Moly coating. Moly reduces friction during the critical break-in period and helps dissipate heat as well. | |||||||
| *all pistons are sold with
wrist pins, rings, and clips (unless noted). **all piston kits include one piston only. |
