    Review & Install Video

    Hey everybody, I'm Justin with, and this is my review of McLeod RST Twin Disc Clutch, available in sizes for your '01 to 2014 Mustang GT and Boss, in addition to your '03 to '04 Cobra and Mach 1. In the world of aftermarket clutches there is obviously a ton to choose from and I think you'll find McLeod to be one of the more premium options in the world of clutches. Now they do offer anything from your bone-stock daily driver or light bolt-on car, all the way down to your thousand-horsepower strip monster. Now what we're looking at today is one of the big boys, the RST which is a twin disc clutch, and believe it or not, it not even the burliest clutch they do offer. They also offer an RXT, which is capable of holding upwards of a thousand wheel-horsepower. So with all that said the RST is definitely going to be a good option for those of you guys out there who are looking to make or already making big power through either forced induction or nitrous for your street-strip car or your dedicated drag car. Not so much for the cars out there with light bolt-ons or even stock. This thing would definitely be overkill. Now a twin disc clutch, for the most part, is a thing of beauty, because it's going to offer unparalleled holding capabilities with a pedal feel or effort that's not going to kill your leg in the process. Now the only downside to a twin disc clutch is usually the price, as they are not often cheap. The one thing I do like that McLeod has done to help keep some of the costs down here, at least with the pre-MT82 RST, is allow it to be used with any stock or aftermarket flywheel as long as the bolt patterns match up. Now both the Ram and Exedy twin discs here on AM, they do include flywheels, which is only going to increase the price. Now for the MT82 crowd, both the '11 and '14 GT and Boss owners out there, McLeod strongly recommends you use their RST with the McLeod flywheel for the best fitment, of course, here. Well that is going to increase the price, but as always, you have to pay to play. Getting into some of the specifics here with the RST we'll notice dual organic material friction plates here separated by the floater plate, the signature red McLeod pressure plate, and last but not least, the adapter ring. Now it's not uncommon to experience a little bit of noise at idle with a twin disc clutch here, and that will be the case with the RST. At least some of our customers have pointed that out, so be sure to check out those reviews if you haven't done so already. Installing a new clutch can be a little tricky if you've never done it before and especially if you don't have access to a lift, so for that reason alone I'm going call this one three out of three wrenches on the difficulty meter. I might knock that back to a two out of three wrenches if you do have access to a lift because obviously it's going to make life a whole lot easier. Figure the trans does have to get dropped obviously for this one, so we'll call it four hours or less from start to finish. And also another biggie here, make sure you follow McLeod's braking procedure for the clutch to get the most life and performance out of the clutch itself. So if you're looking for a proven clutch for high horsepower applications that's going to maintain great pedal feel and drive-ability, you have to consider the RST from McLeod, and you can find yours right here at

    Street Or Strip. The McLeod RST Twin Disc Clutch is perfect for aggressive street driving and occasional drag strip use. Able to hold up to 800hp the RST Twin Disc Clutch kit is ideal for extreme horsepower Mustangs that need a good reliable street clutch.

    Twin Organic Discs. Featuring organic faced twin sprung hub friction discs; this RST Clutch will provide smooth engagement with a soft pedal effort and excellent release characteristics, making this a very driver friendly clutch suitable for all street performance enthusiasts.

    • Fits: 2003-2004 Mach 1 with a TR3650
    • Fits: 2001, 2008-2009 Bullitt with a T-45 or TR3650

    For cable equipped Mustangs Mcleods Adjustable Clutch Fork-Ball Stud (part# 16909) and Throw Out Bearing (part# 16100) are recommended.; Use of an aftermarket Mcleod Steel Flywheel is highly recommended for maximum horsepower holding capacity.

    It's recommended that you add an SR Performance Braided Stainless Steel Hydraulic Clutch Line during your new clutch install. Stock plastic clutch lines can fail during aggressive driving. Stainless steel clutch lines help prevent gear lockout and provide superior clutch pedal feel, even under the toughest conditions.

    Technical Note. Because Ford made changes to the Mustang GT and Bullitt in mid year of 2001, be sure to check and see what kind of transmission type you have before ordering.

    Will this work with a 8 bolt main/8 bolt FRPP Billet Steel Flywheel and 10 spline input shaft?

    • Yes, this will work with an aftermarket flywheel as long as it maintains the same bolt pattern. This also will work with a 10 spline input shaft.

    What's the differences in splines? From the 10 spline to the 20 something? Is there pros and cons or is there a certain spline needed for my car? How can I figure out what spline my car needs if so?

    • Hi, Spine count is determined by the input shaft on your transmission, Pre 2011 V8 Mustangs came with 10 spine input shafts from the factory if you have a stock transmission then you need a 10 spline clutch kit , If you are unsure the only way find out if you have a stock trans is to check the transmission tag or check the clutch on the Mustang now.

      smooth as silk

      compared to the exedy that we replaced. this is a very smooth clutch without presenting you with the opportunity to develop hard calf muscles. Very little pressure takes it to the floor and enhances the shifting. Very Pleased. Dr. Bob Bruce ps The car is the one of one Roush Bullitt

      Awesome clutch

      Install was pretty easy and the instructions that came with it are good. I'm still in the break in process, but so far it's nice. The clutch is almost like stock. Very nice clutch for the price. As stated in the video the clutch is a little noisy at idol , but most of that noise goes away after the first few days of break in.

      Rat clutch for 03 terminator

      My centerforce clutch's pedal pressure was too hard for my ankle issue n I thought about converting cobra to aod but it became expensive n difficult to Get done. After installing the McLeod rst clutch pedal pressure is so easy I don't have to sell my cobra which I thought I would have to do. Dealing with the team at McLeod n american muscle was my solution to happiness. Thank u guys nick sileno 03 cobra solid axel n stage 1 upgrades.

      Nice clutch

      This is a real nice clutch easy pedal and grabs like crazy but it may be a little extreme for the street it doesn't slip very much and can be a bear to drive in traffic.

      05 10.5 psi this clutch was over kill I know but didnt want to loose any drivability have to go to after market clutch after supercharger fried the stock one making 500+ trq.. This clutch drives great matched with new bearing and stailiess slave cylinder and new slave unit also from AM combo worked great one thing I would say.... Don't forget about your flywheel had mine resurfaced.. Think it was wrong choice.. Flywheel didnt balance.. Car shacks at idle.. Tore it back apart and had to do new flywheel also just invest in new flywheel also save you some time and money
