I updated the OP with this link to show the obvious issue.




another thing I found out that should probably have some questions brought to light:

i noticed that there are many sellers on ebay that sell McLeod clutches. Something I found interesting is that although 95% of those sellers are located within 15 minutes from McLeod, they all seem to have the same answers to the questions being asked about any of the issues that are brought up(almost as if they work at McLeod Racing and not just sell their products on the side). Aside from that, None of them offer any sort of warranty or guarantee on any of the McLeod clutches. I even had one respond asking me why I was asking?!?

seems to me like McLeod is pawning off a bunch of their products that they know are poor quality and shielding themselves and their reputation behind a supposed third party, who won’t bother backing the product for the reason of “nature of performance”. Or maybe their sales team all has individual ebay accounts for commission. Maybe I’m wrong, but it sure doesn’t look good on the surface.

Finally got it to a point where it would work. Turns out it also bent my input shaft. The trans was fresh from Tick. After installing a Monster triple disc and having shifting issues, I sent the trans back to Tick and they found the input was bent.
Also, McLeod customer service fought with me the entire time.
I even posted on here about the initial issue and service and got blasted a few times on how great they were. Yea, well this just reinforces my dealings as well.
Even my Monster triple had an initial problem with the pressure plate. They asked 3 questions, sent me a label. 5 days later had it back in the car, broke it in for a few miles and hooked so hard, broke the Trutrac carrier in the Moser 12 bolt.
No Nitrous on this. All N/A.

looks like I’ll be going with Monster(or any other brand for that matter). The customer service I received from McLeod was SO poor that I couldn’t even fit everything I had to say in the original post.

the part I left out was the fact that after the first clutch that chattered, the rep wt mcleod suggested i go with a RST clutch instead. I asked him if it would be sufficient enough to hold at my power level and weight. He tells me I will be fine. Mind you, I have ALL of this in writing…

3 months go by and the RST is completely done. Zero track passes and was broken in properly. The difference was that this one didn’t chatter. It just couldn’t hold the power.

so I reach out to the same rep who recommended the RST. And he tells me “i shouldn’t be running the RST. I should have gone with the RXT instead”. Then proceeds to quote me on a price for the RXT. You can’t make this stuff up! Its all in writing Too!

The only thing worse than the quality of these clutches is their quality of customer service. Absolutely trash! which is where their products end up, if you buy them.

Folks we can't comment on the RXT, but this goes back to our statement about spline quality and heat treat being two key pieces of the puzzle. Some had asked how much spline thickness we have. The splined section of the forward disk is 18.4mm (.750 in.) thick. The rear is 12.3mm (.485 in.) thick. for a total of 1.235 in.. Note this does not include the intermediate plate which is pretty beefy on ours to minimize warpage. Also, the weight of the rear and front disks should be slightly different to guard against harmonics. We've had some customers starting to get up in the miles now without reported issues.

This dates back to my ordeal 4 or 5 years ago when I said I will NEVER run a McLeod again. It cost me an input shaft as well.

Thanks for this. Really appreciate it. Can anyone compare this to the RXT or better yet compare the input shaft fitment like in the video?

When you say compare "this", do you mean the Summit Twin disc? I've been running it for awhile and it was NOT loose like that RXT vid, that's just awful. I've been very happy with my kit and its definitely a well put together piece for sure.

Again .. **** McLeod. They absolutely do NOT stand behind their work. They may stand behind a brand new clutch, but then you will realize that that pain in your *** is a McLeod *****.

Exactly. That's all I'll install in my own cars and other guys cars. 2 of mine have a twin disc and my sons has a triple disc. Couldn't be happier.

This is making me nervous...I just bought a McLeod RST for my LS3 swapped Z. Not sure if I wanna use it now. Car is being set up for drag but street as well. Will be putting down roughly 480-500 at the crank so, what do you all think? I read great reviews about McLeod so this is disheartening.

Long as you don't plan on a bunch of launches on a good tire it'll be fine. Your light weigh helps too.

I am sure the clutch will work great, since it is new. When you send it for a rebuild, you will suddenly have sharp pains in your lower colon.

Lmao. If I ever need a new clutch later on then I'll look into monster. I almost got their twin disk as compared to the McLeod. Surprisingly my stock clutch held up to 50k miles of abuse, but only to bolt on LS1 not a cammed LS3.

Although I will be beating the living hell out of these clutches, I do mainly drag racing but not with slicks so we will see what happens. It should hold up.

It will hold up. I was happy with the Street Twin clutch that I had, until the rebuild, but the ability to have it rebuilt is the only reason to buy McLeod. Unfortunately, they lost all of my business, and respect with the epic failure of their rebuilding process

It's unfortunate the amount of time and labor you put in to use these setups only to result in short term issues. I just had an RXT 1200 balanced with a billet flywheel (going into a Procharged C6). Will report back with any issues. This is a brand new clutch (2022 build date).

I have been running an RXT in my stroked LS3 Camaro for 3 years. Bought the one in my Fbody used, rebuilt once already with no issues. I beat on the car every time I get behind the wheel and have lifted the front end off of the ground a few times at the track (565whp/570wtq) lol.

I almost bought an RXT but I'm happy with my decision to go with Monster Clutches. I'll be going to a triple disk on my next one if and when this twin disk finally craps out..
