Product Details

The Wiseco K643M955 is a shelf-stock forged piston kit designed for the Nissan VQ37 engine family. Wiseco's shelf-stock kits provide a ready-to-ship performance upgrade using the same high-quality forged aluminum construction found in their custom piston lines, making them an ideal choice for engine builders seeking durability and performance without extended lead times.

These pistons feature a 95.5mm (1.198-inch overbore) diameter, making them suitable for overbore rebuilds and performance engine builds. Wiseco forged pistons are manufactured from 2618 alloy aluminum, offering excellent strength and heat resistance under high-performance and forced-induction conditions.

Key Features:

  • Forged 2618 aluminum construction for superior strength and durability
  • 95.5mm bore diameter — designed for overbore applications on the Nissan VQ37
  • Shelf-stock availability for faster turnaround compared to custom orders
  • CNC-machined to tight tolerances for proper ring seal and reduced friction
  • Compatible with the Nissan VQ37VHR engine platform
  • Includes full piston set for complete engine rebuild

Wiseco is a trusted name in performance pistons for automotive, powersports, and racing applications. The K643M955 piston kit is engineered to meet the demands of street performance, track use, and forced-induction builds on the VQ37 platform.

Purchased my mishimoto heat tape. Cheapest price around and the shipment was delivered in a very reasonable time. Couldnt be happier

Best price on the internet for my parts. Shipped out the next morning.

Thanks for having the part we needed for a great price!

Very fast shipping, always great prices.

shipped fast, cant wait to put it on the jeep, would buy from here in the future.

quick, easy and great price

I'll admit to being skeptical at first, but the price was worth the risk. Turned out to be one of the best online transactions I've experienced. Received item 3 days after purchaseing and the best price I found. And I looked hard! A+

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.
