Whos taken the splines off the input shaft with an RXT? https://cimg9.ibsrv.net/gimg/ls1tech...fd4932b7f2.jpg https://cimg2.ibsrv.net/gimg/ls1tech...34881e286e.jpg https://cimg1.ibsrv.net/gimg/ls1tech...4d1d43a909.jpg So far its ruined 2 inputs with this clutch and 3 hubs, Mcleod warrantied it the first time and said if it happened again they would stand behind it but they arent returning my calls this time. ive looked into getting a stronger input with no luck, im basically stuck going with G force internals if i want a stronger input and that is BIG money, 5Gs for gforce to build my T56. Keep in mind im NA and making 435 at the wheels. The really bad input shaft failed after the clutch was installed for 2 months. The other that isnt as bad has 3 track days on it with a total of maybe 10 passes the rest street driving. |
Search, there has definitely been at least a couple of threads on the same problem in the past year or two. |
And with only 435hp... any good single plate would be more than adequate. And a single would offer you a lot more spline engagement But it does seem McLeod do have issues with their hubs, which then in turn can damage the input....NOT a good situation. |

I know its more clutch than i need but its the best driving clutch ive had and the pedal feel is great. I also like it because it hits the tires so hard to get that perfect amount of tire spin needed to keep it from bogging. |
Not much use if it fucks itself up and the input shaft ! lol Although in the other threads, the hub splines on one disc got completely stripped, yours just look worn. https://ls1tech.com/forums/manual-tr...-rxt-fail.html https://ls1tech.com/forums/manual-tr...put-shaft.html |
This set is just worn however my last set the outer got completely stripped just like the 2nd input shaft i posted. its been warrantied once, maybe 10 track passes and a season worth of street driving wore this one out. |
When I first put an LS1 engine in my car, supercharged way back in 2003 or so. I started abusing the life out of it around 2005, and a larger better engine etc, racing as often as I could. At around 3700lbs then I got down to 10.04 at 149mph on a Textralia OZ700, just a plain single plate. It drove extremely well, pedal not heavy and I easily had a few hundred passes on it, best 60ft only around 1.7 though. I put maybe 12k on that driving about and to/from racing and it was faultless and when I finally did remove it, it was really only just fully broke in ! I still keep it as a spare. At your power level etc I cannot see any good reason to be running a metallic type twin disc. Now that isnt your problem here anyway, it's clear something about McLeod's hubs are pure shite.. But just saying a good single will easily cover what you need and have almost zero risk of spline problems. But no, 10 passes and a year of driving have not worn it out. You should be able to to do tens of thousands of miles, hundreds of passes.....and it should still not be worn out....or barely worn at all. That said, I'm sure a Monster, ACT or indeed many other makes of clutch would work great for you either in single or twin. |
I've heard nothing but good things about Textralia and diamond clutches. |
FWIW a few years ago I asked Billy @ McLeod if their hubs were made USA or offshore...he said USA I make about 30 HP less than OP with a 4200 lb car and I run a MT ET Street at the track and have hundreds of passes behind my McLeod "Street Twin" (organic disc). This clutch hits hard and I have always feared something downstream of the clutch will fail but so far nothing. I usually leave about 2500-2700 RPM. Can't say anything bad about my McLeod and have had it for 3-4 years now. I usually only got one season out of single disc clutches and the ceramic puc type sucked for chatter in city driving Was the input shaft that was replaced a Tremec shaft or aftermarket?? Op's car must hook hard |

The centre hubs had moved on the rivets on 2 discs, and the little rivet washer things that hold the diaphragm pivot to the cover were starting to bend. I tried several times to get replacement parts but to no avail so gave up. As I didnt really intend drag racing the car I bought a ACT twin organic so it would be 100% normal to drive and that clutch lasted me for several years before it finally just let go under power during a standing 1km run. TBH it had held power extremely well until that though, I was impressed. The clutch I then replaced that with, turned into a nightmare...wish I'd just bought another ACT instead ! |
Theyre both tremec input shafts, no chinese stuff here. |
Im hoping theyll warranty this, either way im out a lot of money, 3 input shafts to the tune of 450 each = 1350, plus the cost of the clutch if they dont warranty it. If they dont warranty Ill have to go back to the clutch i used to run which is a ram sintered iron single disc which is going to cost me another 850. |
I'd like to see footage of how you drive that thing |
I don't see why a simple single like this wouldnt easily do what you need and is nowhere near 850 https://www.advancedclutch.com/produ...=p3594-c201748 Or sprung to be a little more forgiving. https://www.advancedclutch.com/produ...=p3593-c201739 Or even this certainly has plenty of torque capacity, although if you were doing lot of hard launches, the above would probably be better https://www.advancedclutch.com/produ...=p3592-c201731 Seems to be 15% off the prices at the minute so all in the $4xx range. |
Or their range of twins, which include flywheels. https://www.advancedclutch.com/produ...sc-clutch-kits |
Looks good I like the unsprung heavy duty version only problem is they only offer one flywheel that i can see and it is too light. |
What do you mean they offer one flywheel ? The single kits bolt to the original flywheel. Or they do offer twin kits with either a lightweight flywheel ( with holes ) or full steel flywheel And even the one with holes is by no means light by the time it's all bolted together. |
https://www.advancedclutch.com/produ...olite-600585-2 this is the only flywheel i could find and its 17lbs. my car works well with a 30lb flywheel. |
Oh, you're talking about their single disc flywheels. Just use any stock flywheel or equivalent ? What flywheel are you using with the RXT ? Dont their kits adapt some BS to bolt to a stock flywheel ? |
