The clutch in my 73 LS4 is starting to slip in 3rd and 4th gear during WOT. I'm quite sure it's the orginal clutch and long overdue for a new one, which leads me to ask; have any of you folks replaced a clutch recently ? Now that it's winter in Michigan I've got time to get back to my repair / restoration tasks, I haven't really looked at what my options are as far as clutch replacement parts. Any experience / advice would be welcome.
Thanks,

Mike

73 LS-4

I just put a centerforce dual friction on mine, it's only been in for about 20 miles so far so I can't give much feedback on it. The advice on this board is that they are excellent, a buddy of mine with a 72 small block car also had one and loves his as well. Deffinitly stickier then the stock clutch was just in daily driving, it has a break in period so I really haven't abused it as of yet. One thing of note though on the LS-4 possibly. According to the application guide it should be something like an 11 spline input shaft, but mine was a 26 spline shaft. My car as far as I can tell everything was original and the application guide shows the 26 spline accurate for the 73 L-82. In short I ended up using the 26 spline clutch for an L-82 on my LS-4, and ended up returning the 11 spline clutch. So if you have some time to pull the tranny you may want to look at your input shaft before ordering a clutch. Oh yea, don't be scared of a performance clutch like this, it's not any noticeably stiffer then my stocker was.

I just replaced mine a week ago. I used the Centerforce II. I only have about 10 miles, its been raining all week here.

I went with the II because I wanted more than a stock clutch and not the grabbing of the Dual.

Your 73 will take the 26 spline 11" disk.

You will do fine with a stock clutch. As long as the disk is new and not rebuilt. Hayes is also a good clutch. I like my Centerforce 2 but I had problems with the clutch geometry. The Centerforce is a pain in the butt.

I installed a Centerforce Dual Friction about 1,000 miles ago and it works great. Jegs had the best price on the clutch, pressure plate and throwout bearing. Some people have had to install a adjustable pivot for the clutch fork.

Hope it all works out OK.

Hi,

I have just changed the clutch in my 81 and fitted a QuarterMaster twin plate set-up. It works well once you get used to it. They can be used on big or small block cars. Expensive but the quality of the parts is excellent. I have only done a 100 or so miles with it so it will remain to be seen how long it lasts.
