Product Details

The McLeod 6340607 Original Street Twin is a high-performance dual-disc clutch kit engineered for Mopar applications with 340, 383, and 440 cubic inch engines. Featuring an aluminum flywheel, this kit is designed for the serious street enthusiast who demands exceptional torque capacity without sacrificing everyday drivability. The kit fits 6-bolt flywheel configurations with a 1-1/8" x 26-spline input shaft and a 130-tooth ring gear, making it compatible with a wide range of Mopar muscle car transmissions from 1964 through 2003.

Key Features:

  • Dual-disc (twin-disc) clutch design for maximum torque capacity up to 1,200 horsepower
  • Aluminum flywheel construction for reduced rotating mass and improved throttle response
  • Compatible with Mopar 340, 383, and 440 engines (1964–2003)
  • 6-bolt flywheel pattern with 0 balance specification
  • 1-1/8" x 26-spline hub fits common Mopar manual transmission input shafts
  • 130-tooth ring gear for proper starter engagement
  • Street-friendly design — smooth engagement suitable for daily driving and spirited street use
  • Compatible with power adders including nitrous oxide, superchargers, and turbochargers
  • Engineered and manufactured by McLeod Racing, the original innovators of the Street Twin platform since 1974

Born in 1974 in response to the growing popularity of forced induction and nitrous-assisted engines, the McLeod Original Street Twin set the benchmark for high-horsepower street clutch systems. Unlike single-disc alternatives, the twin-disc layout distributes clamping load across two friction surfaces, dramatically increasing torque capacity while keeping pedal effort at a manageable, street-friendly level. Whether you're running a big-inch naturally aspirated motor or a power-adder combo, the Original Street Twin is built to handle it.

Very good give you 5 stars

great

Very very good, even great! Best prices on the web and fastes service. Will continue to purchase all my automotive needs from here!

These guys had great pricing and got my order to me very quickly. I would do business with them again for sure!

This my first time to purchase from this company and it was easy and fast. I will be back!!!

I bought a set of 3 MSD Ignition coils for my 2001 Impala LS 3.8 and I am very impressed and satisfied with my purchase. I got an email right away stating what I purchased and within a day or two I recieved a shipping confirmation. My ignition coils arrived fast and I had no problem with the coils been bad or broken. The coils are awesome. There is a significant difference between my old ones and these 3 new ones. The car is very responsive to the accelerator and as stated in the MSD website, the car gained some horsepower. I don't have to press the accelerator in that much to gain the power I need. I'm impressed overall.

Your site is great, just the part I need.

Autoplicity was great. The cheapest price and excellent delivery. I will use them again.

Ordered a DiabloSport tuner for my truck here, as they had the lowest prices on the web with shipping. Order was placed on Saturday and shipped Monday. Although I received my tracking number on Tuesday, I was pleasantly surprised that they had already shipped it out. Nonetheless, my transaction was flawless. I would order from them again with no doubts.

Great store! Best prices, fast fedex shipping. Very satisfied, will buy from Autoplicity again!

Price was perfect, I will definitely be shopping here again.

Nice product, I relly liked these fog lights and they made a difference in visibility. The packaging was pretty good aswell for the shipping aspect.

Very quick service and lowest price.
