Wiseco SK1413 Complete Top-End Piston Kit for Ski-Doo 600 HO E-TEC Dual Ring 72mm

The Wiseco SK1413 is a complete top-end piston kit engineered for Ski-Doo 600 HO E-TEC snowmobile engines. Featuring a dual-ring piston design at a 72.00mm standard bore, this kit delivers everything needed to perform a full top-end overhaul or overbore in a single purchase.

Wiseco forges all pistons in-house at their facility in Mentor, OH, using dedicated aerospace-grade alloy forgings to achieve a superior strength-to-weight ratio. Compared to cast pistons, Wiseco's forged construction provides condensed grain alignment that results in higher mechanical properties and resistance to impact and fatigue — critical for the demanding thermal and mechanical loads of high-output 2-stroke snowmobile engines.

Kit Includes:

• 2 forged Pro-Lite pistons — CNC machined for optimal cam shape and profile for peak HP and service life
• Dual-ring set — Wiseco high-performance rings matched specifically to these pistons
• Wrist pins and circlips
• Complete top-end gasket set

Specifications:

• Bore Size: 72.00mm (Standard)
• Engine Type: Ski-Doo 600 HO E-TEC (2-stroke twin)

Important: Wiseco rings are not interchangeable with other brands and must be used only with Wiseco pistons. Cylinder sleeves must be purchased separately if re-sleeving is required. Note that oversize piston applications require cylinder re-sleeving.
