Product Details

The McLeod Street Twin is a high-performance dual disc clutch assembly engineered for street-driven vehicles running serious power adders. Developed to meet the demands of nitrous, supercharged, and turbocharged applications, the Street Twin strikes the ideal balance between daily drivability and the ability to handle up to 1,200 horsepower — all without the harsh, unforgiving pedal feel typical of race-only clutches.

This aluminum flywheel-equipped kit is specifically configured for Mopar 1963–1972 Hemi and Wedge engines with an 8-bolt crank pattern. It uses a 1-1/8" x 26-spline input shaft and a 143-tooth ring gear, making it compatible with aftermarket transmissions in high-performance Mopar builds.

Key Features:

  • Dual disc (twin disc) design for maximum clamping force with reduced pedal effort
  • Rated to handle up to 1,200 horsepower — ideal for power adder applications
  • Street-friendly engagement for comfortable daily driving
  • Lightweight aluminum flywheel reduces rotating mass for improved throttle response
  • Fits Mopar 1963–1972 Hemi & Wedge engines with 8-bolt crankshaft flange
  • 1-1/8" x 26-spline input shaft compatibility
  • 143-tooth ring gear for aftermarket starter compatibility
  • Designed for use with aftermarket transmissions

The McLeod Street Twin is the go-to solution for Mopar enthusiasts who demand race-level clutch capacity without sacrificing street manners. Whether building a high-horsepower muscle car restomod or a track-day machine, this twin disc clutch kit delivers the holding power and longevity needed for serious performance builds.

Thanx it was so easy to order

hey had what I needed at a low price and were easy to deal with.

Nice!

Simple ordering process, and the product was exactly as advertised.

Best price by far! Fast shipping!

Easy!

easy peasy

Good so far.

Everything went smoothly, love the prices and the ease of transaction, hope to buy from you real soon, Nice people.

well made website would give 5 stars if i could confirm fast shipping.

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

Great

Fast shipping, exactly what I was looking for, at the best price I could find! Thanks!!

easy
