Product Details

The McLeod 6300307 Original Street Twin is a high-performance dual-disc clutch kit engineered for classic Chevrolet small block and big block applications. Featuring an aluminum flywheel, this twin-disc system dramatically increases clamping force and torque capacity over a single-disc setup while maintaining streetable pedal effort — making it an ideal upgrade for high-horsepower street and street/strip builds.

Designed to fit 1955–1985 Chevrolet Small Block (SBC) and 1970–1990 Chevrolet Big Block (BBC) engines, the kit uses a 1-1/8 in. x 26-spline input shaft interface and is compatible with 153-tooth flywheels, matching standard Chevy bellhousing patterns.

Key Features:

  • Dual-disc (twin) clutch design for significantly increased torque capacity
  • Lightweight aluminum flywheel reduces rotating mass for improved throttle response and quicker revs
  • Street-friendly engagement for daily driving and performance use
  • 1-1/8 in. x 26-spline input shaft fitment
  • 153-tooth ring gear flywheel configuration
  • Compatible with 1955–1985 Chevrolet Small Block engines
  • Compatible with 1970–1990 Chevrolet Big Block engines
  • Manufactured by McLeod Racing, a trusted name in performance clutch systems

McLeod's Original Street Twin series delivers the torque-handling capability of a racing clutch with the drivability required for street use, making this kit a top choice for muscle car restorations, performance builds, and high-horsepower street machines.

The site is clear and easy to navigate. With so many places to get what I want online it is easy to make a mistake and buy through a shady site. I was buying an expensive item ($500) and wanted to make sure that I was not going to have issues. I did my research and read many positive reviews before making my purchase through Autoplicity. Autoplicity is as legitimate as they come. Things went very smoothly.

Easy to use online experience, we'll see how it goes from here.

Best prices on the net. Great selection.

Quick Shipping and friendly Service

I deal with you before and always find some improvement in your business style and i really like it!Keep it good job! Super fast shipping and outstanding product by fantastic prize,lover then anywhere online.I would recommend this supplier to any car enth

So far so good, quick. Hope you have the part !

Cheapest price, manufacturer direct

The listed matching vehicles were a little vague, still a little uncertain if the part will fit, will have to find out for sure once it arrives

Fast and easy

Ordering was a snap, everyone else had it on back order, please let me know if it is on back order.

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34

A bit pricier than other sites, but if you have the item in stock and I don't have to wait a month to get it.

very easy to find merchandise, transaction was simple, received confirmation quickly, good experience so far

Hands down the best price anywhere. Seamless, hassle free shopping with fast status updates- Bookmark this into your favorites!
