Product Details

The McLeod Street Twin is a high-performance dual disc clutch assembly engineered for street-driven vehicles that demand serious power handling. Developed in response to the growing popularity of power adders such as nitrous oxide, superchargers, and turbochargers, the Street Twin is designed to be completely street-friendly while handling up to 1,200 horsepower — making it one of the most versatile performance clutch solutions available for Mopar applications.

Unlike traditional single-disc performance clutches that sacrifice drivability for capacity, the Street Twin's twin-disc design distributes clamping load across two friction surfaces. This results in a clutch that engages smoothly and progressively under normal driving conditions, yet holds firm under extreme power and boost loads.

Key Features:

  • Dual disc design supports up to 1,200 horsepower
  • Street-friendly pedal feel and engagement — no harsh chatter or aggressive engagement
  • Steel flywheel construction for durability and consistent thermal performance
  • Designed for Mopar 1964–2003 340, 383, and 440 engines with 6-bolt crankshaft flange
  • 23-spline input shaft compatibility
  • 130-tooth ring gear for OEM-compatible starter engagement
  • Complete kit includes pressure plate, dual friction discs, and flywheel hardware
  • Ideal for street/strip builds running power adders or high-compression naturally aspirated engines

The McLeod Street Twin 6440602 is the go-to dual disc clutch solution for serious Mopar performance builds that see regular street use. Whether you're running nitrous, boost, or simply building a high-compression big block, this clutch delivers the holding power and drivability you need.

I was a bit skeptical about your website since I've never purchased from you before, but your customer service representative was great at answering my questions. Thanks.

All Good

Very quick and easy to use. Also love the detailed fitment.

Best price for a product I've been shopping for, for months, and when I saw Autoplicity having it for A LOT cheaper, putting the product in my sweet spot price wise, I didn't hesitate to order. <br><br>My bank was a little slow to post the transaction, and I was suprised to get a human on the phone with no effort to make sure my order was properly processed. The gentleman I spoke with was very friendly and promptly answered all my questions. <br><br>Only the $5 I'm getting back for this review can make this deal any better, as I have no suggestion for improving the transaction I made with them.

Easy to order from really good price. Thanks! Quick shipping received as advertised. Good place to shop
