King Cobra clutch problems***help***

[BDAWK2002]

When I did my TKO swapp in July I installed a new king cobra clutch and a new frpp flywheel.Everything seemed great until a few weeks ago when the clutch started slipping like a ****** I grabs fine if I take off like a grandma but with any kind of power at all it starts slipping.I let it break in as best I could a few burn outs here and there for 1500 miles but nothing to crazy.I have a steeda clutch cable adjuster but I havent touched it because the clutch still seems to grab at the right spot just slips with power.Im wondering if the rear main seal I replaced is leaking on the clutch No sighns of oil leak from the outside though.Anyone have any ideas?????Once I clean my garage out i'm gonna pull the trans and find out whats going on but that's a few weeks away.

I don't know. 1500 mile burnouts sound a bit extreme to me!

I just put in a King Cobra last week and so far it's holding up on me. From everything I've read it sounds like some kind of contamination like oil or grease would cause that. The only other thing that I can think of is if you had your adjustment too tight you might be engaging the clutch a little bit even though your foot is off of the pedal. You might want to give the cable a little more slack to see if that helps. Good luck.

i dont think break-in is the issue. When i installed mine, about 2 years ago, i was stupid, did a huge burnout, and while i was at it, managed to smoke the clutch....i mean SMOKE....and it has lasted 2 years since then, and has held upto some serious power....it dosent slip currently, and dident slip at 500rwhp on the dyno(i dont think).

lol i dont care what kinda burnouts your doing, i would not do any during breakin. You dont wanna do anything to get the clutch real hott during break in, and any type of clutch drop should accomplish that. maybe u got lucky on your last clutch. I also have the king cobra and i feel like its performance has decreased but i have been racing on mine so thats probably why. Mine still chatters too, grrr

I think your rear main has sprung a leak. It doesn't take much to ruin a clutch. But before pulling the trans i would try loostening up the cable to to be sure you are not riding the clutch all the time.

Oh and take it easy too as I had a clutch do that in a truck and not even 1000 miles after noticing it would slip (100 miles a day) it dies all at once and I was stuck in a parking lot that i was lucky to coast into...

When I installed the KC clutch in my other car the first thing I did was race it around the block and then 10 min later I let my friend race it around the block. I didn't really break it in that well, but it still held strong for 3 years of punishment and was holding strong when I sold the car.

I was so happy with that clutch that I just put one in my new car about a week ago and am currently breaking it in. The sheet it comes with says 500 miles, and I have got about 220 on it so far, I don't think I will baby it past 250, they always over-rate those things for idiots like me.

but yeah it sounds like you have contamination on your flywheel/clutch. You cleaned all the fingerprints and smudges off with break cleaner (not engine degreaser) right? I didn't bother changing the rear main on mine because last time it wasn't leaking and I change it to find out I had created a leak.

Thnxs for the replies.Im gonna try and losen the cable but I dont think thats gonna work.I'm gonna have to pull the tranny and check it out.If the rear seal is leaking I'm gonna flip because the old seal wasnt leaking. I changed it just because the tranny was out.

The KC clutches can take some abuse pretty much right away, even if it's not recommended. And they will last also. I had a Spec stage1 in summer of 94, and burned it in less than 1000 miles. Burnouts and drag races right away without the 500miles breaking period....Like everyone saud, make sure your clutch cable isnt too tight (engaging it all the time).
