Overview

The WSM Platinum Series Piston Kit is designed to prevent skirt and ring groove breakage. Made from high-strength hardened aluminum, this piston features a nonabrasive coating on its walls to reduce heat and friction, contributing to added horsepower and extended piston life. This kit is manufactured to exact OEM specifications and includes the piston, rings, pin, and clips. It is designed as a direct replacement for Yamaha OEM part numbers 66E-11631-01-A0 and 66V-11631-00-A0.

This piston kit is specifically designed for various Yamaha marine applications. Fitment includes the 1998-2002 Yamaha GP 800, 2000-2002 Yamaha GP-R 1200, 2003-2005 Yamaha GP-R 800, 2001 Yamaha XL 1200, 2000-2001 Yamaha XL 800, 1999-2000 Yamaha XL LTD 1200, 2002-2005 Yamaha XLT 1200, 2002-2004 Yamaha XLT 800, and the 2000-2001 Yamaha XR 1800 1200.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
