McLeod’s Super Street Pro clutch for classic and late-model Chevys is perfect for the street and track
Clutch technology has always been about getting a grip and getting power from the crankshaft to the rear axle. How to do that successfully has always been the challenge for clutch manufacturers like McLeod, which has been designing and manufacturing clutch systems since it was founded nearly a half-century ago.
When you’ve been making clutches for as long as McLeod you come to learn a thing or two about how to develop and engineer them for a wide variety of street and racing applications. The objective is to get a clutch to hook up without slippage and do it consistently for years and years and thousands of miles. As we continue to add to the horsepower and torque burden it becomes tricky to produce a clutch that can stand up to the power we want. This is why we looked to McLeod and their Super Street Pro clutch for our LS application.
The McLeod Super Street Pro clutch (PN 75223) for LS applications can take up to 550 horsepower along with comparable torque, which makes it ideal for both the street and track. This SFI-approved clutch and flywheel combo includes a high clamp load pressure plate and a dual-faced organic and metallic clutch disc for smooth engagement and terrific holding power. Organic provides smoothness while metallic gets the grip.
When it comes to clutch friction material, there are several types of frictions for specific missions.
There’s organic and heavy-duty organic for medium-duty street use. Ceramic clutch friction material consists of copper, iron, tin bronze, and silicon dioxide mostly. Because the ceramic clutch facing tends to engage abruptly, it isn’t suggested for street use. However, it is perfect for racing. Kevlar is a nice compromise for street and strip applications because it is so rugged yet forgiving because it offers both durability and smooth engagement. Metallic clutches offer durability and smooth engagement. They are designed primarily for truck use.
What’s nice about these McLeod clutch kits is they arrive with everything you need to perform the installation, including the pilot tool, release bearing (where applicable), and pressure plate bolts (where applicable).
We also opted for the McLeod hydraulic clutch slave/release bearing package (PN 1372) to replace the aging factory unit. It is a drop-in replacement, which doesn’t involve any special modifications. All you need to do is bleed the system upon installation and do an operational check before hitting the road and you’re good to go.
01 | After making room by removing the driveshaft and the exhaust system, the hydraulic clutch braided line needs to be disconnected at the master cylinder above. Have a drip pan available for the stray brake fluid in the system and be careful not to get it on any painted surface; it will do permanent damage.
02 | The shifter handle is disconnected from the shifter by removing two bolts with a 5/8-inch boxend wrench.
