Product Details

The McLeod Soft Lok assembly is a high-performance racing clutch designed specifically for drag racing applications. This competition-grade clutch is engineered for NHRA and IHRA sanctioned racing and is NOT recommended for street use.

Key Features:

  • 11-inch diameter with 1-1/8 inch pilot bore and 10-spline design
  • 168-tooth flywheel ring gear configuration
  • Low static pressure for reduced pedal effort and soft engagement
  • Adjustable spring pressure for tuning capability
  • Zero balance design for high-RPM stability
  • Sintered iron disc for exceptional heat resistance and durability
  • Lightweight aluminum flywheel reduces rotational mass

Applications:

  • Chevrolet Small Block (1955-1985)
  • Chevrolet Big Block (1970-1990)

The Soft Lok delivers harder launches with reduced tire spin, making it the most widely used McLeod clutch among serious drag racers. The complete assembly includes pressure plate, sintered iron clutch disc, and aluminum flywheel. The adjustable spring pressure allows racers to fine-tune engagement characteristics for optimal track performance.

Race-Only Application: This clutch is designed exclusively for competition use and should not be used on street-driven vehicles.

Lowest price and S&H around! Prompt responses! Will def buy from again!

I looked around for few months on where to go to purchase JBA headers for my 01 Tundra. I came across Autoplicity and their prices were untouchable. I even called to speak with a sales representative and he gave me a discount code for my purchase. I would highly recommend doing business and plan on doing more business with them.

Great site. Easy to locate items and they have the best prices! I will be using this site for all my custom parts.

Best price I could find on line, shipped really fast. With how low the price is I was worried but everything came fast and it was the correct parts. This place really keeps the cost of racing down.

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

I have not received my order because it is still the same day I ordered therefore i can not comment on shipping. However I do not worry about that process at all due to the professional look autoplicity.com shows through their website. The prices are the website are the lowest I've found and in-stock quantity is great allow me to find every I needed.

Best price I could find anywhere. Almost 10% less than my typical sources and the item shipped in less than 24 hrs.<br>
