Product Details

The Wiseco K1757 high-performance piston kit is engineered for 2007-2010 Harley-Davidson TC96 engines, delivering 110 cubic inches of displacement with a 10.5:1 compression ratio. This complete kit transforms your Twin Cam into a powerful big-bore setup with -2.3cc dome configuration for optimized combustion.

Premium Construction:

  • Forged from high-silicone aluminum alloy for exceptional strength and heat resistance
  • Advanced manufacturing process ensures consistent dimensions and greater operating strength at high temperatures
  • Coated skirts reduce friction and provide superior wear resistance
  • Made in the USA with precision tolerances

Complete Kit Includes:

  • Two forged pistons with anti-friction coated skirts
  • Premium ring sets matched to piston specifications
  • Chrome-plated piston pins for durability
  • Retainer circlips for secure installation

Ring Package Options:

  • X-Ring Package: .062" top ring, .062" compression ring, .158" oil ring (part numbers ending in "X")
  • XC-Ring Package: .039" top ring, .062" compression ring, .158" oil ring (part numbers ending in "XC")
  • VM-Ring Package: 1.2mm steel gas-nitrided top ring, 1.2mm cast iron taper scraper ring, 2.0mm three-piece flex-vent oil ring with chrome-faced rails

Installation Requirements:

  • Requires big-bore cylinders for 110 cubic inch displacement
  • Case boring necessary for proper fitment
  • ECM recalibration required for optimal performance
  • Professional installation recommended

Important Notes: Ring packages are not interchangeable between X, XC, and VM configurations. Replacement rings are sold individually (one piston only). Wiseco pistons must use matching Wiseco ring types—VM-ring pistons require VM-rings, XC-ring pistons require XC-rings.

I enjoy shopping autoplicity, normally I make my purchase though friends or at work, but I saw a deal that was better than everyone else. I missed a deal you guys had before, only wished I got it for that price back than. Besides that overall im pretty happy. I have had always good service and products from you guys. :D

I really liked the price and being able to use PayPal is a big help.I really wish the shipping was a little cheaper.Overall I would definitely buy from here again!Thanks PS I need this ASAP!!

why

These people are just awesome! I got my Thule Bike Rack for a fraction of the cost compared to everywhere else. Shipping was very fast and cheap but when I received it there were a couple of missing hardware parts. Thule wanted to make me ship the whole thing back. Rob Fratu of Autoplicity took control of the situation and got Thule to ship me the missing parts and some extras, all within a couple of days. I cant remember a better experience with a retailer.

Great price on the product. Delivery time was faster than expected.

Only one word....FANTASTIC..Thank you Bob in Pa.
