Product Details

The Wiseco SK1178 is a complete Pro-Lite forged piston kit designed for Polaris 2-stroke snowmobile engines, featuring a standard bore of 68.25mm. Built for riders who demand performance and reliability during top-end rebuilds, this kit includes everything needed for a proper engine refresh in one convenient package.

Pro-Lite Forged Construction:

  • Aerospace-grade aluminum alloy forgings deliver an optimized strength-to-weight ratio for instant throttle response
  • CNC-machined for optimal cam shape and profile, maximizing horsepower and service life
  • Forged grain structure provides superior resistance to impact and fatigue compared to cast pistons
  • Race-proven design chosen by top snocross and cross-country race teams

Complete Kit Includes:

  • Forged Pro-Lite piston(s)
  • High-performance piston ring kit
  • Alloy wrist pin(s)
  • Top-end gasket kit

Specifications:

  • Standard Bore: 68.25mm
  • Engine Type: 2-Stroke
  • Application: Polaris Snowmobile
  • Note: Cylinder must be bored and honed to size before installation

Wiseco forges and machines all pistons in-house in Mentor, OH, USA, maintaining strict quality control from raw material to finished, skirt-coated component. The SK1178 kit provides a one-stop solution for restoring your Polaris snowmobile's top end to peak operating condition.

So simple and easy. Love the super fast shipping.

Great prices!

Fair product price and shipping was reasonable

Good and fast.

awesome

So far I have a problem. I have a Bilstein steering dampener that I was wanted to mount with this kit. I have discovered that it mounts differently than the Roadmaster. So this kit will not work with the Bilstein. Would it be possible to purchase just the Roadmaster stabilizer without the mounting kit, because, of course, I already have the mounting kit. Monty

It tells me that it works for my car model which is great and has a great price and easy ordering process. But 1 of the pictures doesn't seem to be of the part. That was kind of confusing and has me concerned.

Im very satisfied with how fast i received my product from Autoplicity! The whole process was hassle free. If you looking for quality product for a great price than i would recommend Autoplicity!

Easy to order quick response and got what I wanted.It is very hard to trust a online store curently, but Autoplictity will be on top of my list.
