If you're serious about drag racing, you’ve probably heard of the McLeod Soft Lok assembly. It’s pretty much the go-to clutch for anyone looking to get serious about their runs on the strip. Just a heads up, though—this isn't something you'd want to toss in your daily driver. It's built for performance and has the NHRA and IHRA records to back it up.
What I love about the Soft Lok is how it makes launching your ride feel effortless. With low static pressure, you get a light pedal effort that doesn’t wear you out during those long race days. The clutch engages smoothly, which means you can hit the starting line harder without worrying about excessive tire spin. Trust me, that’s a game changer when you’re trying to shave off those precious milliseconds.
This assembly comes with adjustable spring pressure, so you can fine-tune it to your liking. Plus, it’s available with counterweights, giving you even more control over your setup. The package includes a pressure plate, a sintered iron disc, and an aluminum flywheel, all designed to work seamlessly together. Speaking of the flywheel, it’s lightweight and made of aluminum, which helps with overall performance and response.
As for the specs, you’re looking at an 11-inch disc diameter, perfect for that Ford Big Block engine from 1969 to 1978. It’s designed for internal balance, and it comes with a solid hub style. You’ll also find a 176-tooth ring gear in there, making it a solid choice for any drag racing application.
So, if you’re running a Ford Big Block and want to take your drag racing to the next level, the McLeod Soft Lok assembly is worth a serious look. It’s built for the track, and once you get it in your car, you’ll see why it’s such a favorite among racers.
