Product Details

The Wiseco K681M9558AP Professional Series piston kit is a premium forged racing piston set engineered for serious performance builds. This complete kit includes 6 pistons featuring a 95.58mm bore diameter (0.08mm oversize), 34.30mm compression height, 9.5:1 compression ratio, and -1.8cc dish volume. Each piston includes premium piston rings and 23mm wrist pins.

Professional Series Features:

  • Forged from 2618 high-strength aluminum alloy for superior tensile strength and heat resistance
  • ArmorGlide skirt coating reduces friction, minimizes wear, and allows tighter piston-to-bore clearance
  • Armor Plating technology increases ring groove durability and prevents micro-welding
  • Fully machined crown with precision ring grooves and anti-detonation groove
  • HD2 asymmetric skirt design for improved stability
  • Gas ported for enhanced ring seal
  • Forced pin oiling for improved lubrication
  • Engineered, forged, and machined in the USA

Wiseco's Professional Series pistons are designed for heavy to severe duty racing applications where maximum durability and performance are required. The 2618 aluminum alloy construction provides exceptional strength under extreme temperatures and pressures, while the ArmorGlide coating reduces operating friction for improved efficiency and quieter operation.

Found you on ebay, best deal on the part I was looking for!

hope you have everything

Thank you!

I ordered new leaf springs for my Jeep Cherokee. Its already headed out to me. Ordering was nice and easy. I'll post more once i get it.

Product was the cheapest I could find. One other store was cheaper but did not have my product in stock. Autoplicity shipped within 2 days and the product arrived as described. I am happy with my purchase and would do business with Autoplicity again. The only thing I marked them on was that I wish they shipped within 1 day instead of 2.

This was my first time buying from Autoplicity. I had never heard of the site but gave it a shot. I ordered an Autometer gauge and pod and paid less than the price of just the gauge at other vendors. The two items shipped a day later (I ordered Sunday, shipped Monday). I have no complaints at this time.

I just received my order 7260 very quickly and it was as I had ordered............very easy to order and would do business with them again and I also will recommend them to others.

Good

Your site said if I signed up I could get a discount of some sort. Did not specify the amount. Would like to have that applied.
