Product Details

The McLeod 6300304 Original Street Twin is a high-performance twin disc clutch kit engineered for Chevrolet small block (1955–1985) and big block (1970–1990) applications. Rated to handle up to 1,200 horsepower, this kit was purpose-built for high-horsepower street machines running power adders without sacrificing daily driveability.

McLeod pioneered the street-friendly twin disc clutch concept in 1974 in response to the growing popularity of nitrous, superchargers, and turbochargers. The Original Street Twin remains the benchmark twin disc clutch kit for serious street performance builds — combining race-level torque capacity with a pedal feel and engagement characteristics suitable for street use.

Key Features:

  • Up to 1,200 HP capacity — handles nitrous, supercharged, turbocharged, and large cubic inch builds
  • Aluminum flywheel included — lightweight billet aluminum construction reduces rotating mass for quicker throttle response
  • 153-tooth ring gear — compatible with standard Chevrolet starter configurations
  • 1-1/8" x 10-spline input shaft — matches Chevrolet SBC and BBC manual transmission input shaft specifications
  • Twin organic disc design — provides smooth, progressive engagement and excellent release characteristics for street use
  • Blanchard ground floater plate — precision ground for consistent clamping force and reduced noise
  • Street-friendly pedal effort — lighter than a comparable single-disc setup at equivalent torque capacity
  • Designed and manufactured in the USA by McLeod Racing, the originator of the street twin disc clutch

This kit includes the pressure plate assembly, two organic friction discs, floater plate, aluminum flywheel, and alignment tool. The McLeod 6300304 is the go-to twin disc solution for classic Chevy muscle car builds pushing big power while retaining street manners.

Easy shopping and fast checkout, but this isn't the part I needed...

Great deal on my purchase. Tracking # given once order shipped 2 businesss days later. Good merchant.

I had not shopped at Autoplicity before this purchase. Everything worked out great - product was delivered very quickly and exactly what I ordered. Thank you Autoplicity.

I've only just placed my order but the item cost less with you than anywhere else and the ordering process couldn't have been easier. Thanks!

easy

I saved almost %50 using autoplicity. I did not think that I would be able to afford the Odessy battery for my gold wing as they were priced around $175.00 I found one with Autoplicity for less than $100 they shipped it 2 days after if placed the order!

Have been looking for that piston for weeks, so glad you had it!

Quick easy painless
