Does a 6puck clutch need to be broken in?

thanks

Puck clutch doesn't need any break in.

 

How about ACT clutch?

 

If you are talking about the SS clutch, then according to thier literature, yes.

 

ATC needs no break in either

 

If you throw a clutch in and go dog your car the clutch will more then likely slip. Pucks really don't need a break in but discs do.

I had a friend that didn't break in his ACT. It didn't last 1k miles! He bought the same clutch again and broke it in that time and it lasted a long time.

What's in going to hurt?

 

what is necessary to break it in? (how many miles, etc..)

 

I just ordered a clutch/flywheel combo tonight. ACT SS clutch and RB 9.5lb flywheel. Will the lighter flywheel require any less mileage for break-in? I would assume that less rotational inertia would keep from ripping into the clutch too hard, but would the same number of miles be required to break it in since there will be more slipping done to compensate for the lighter flywheel?

 

I do about 500 miles and try not to slip it during break in. At first it may slip easily, just learn it and try not to.

I wouldn't suggest anything less then 200 miles. You don't have to be super easy on it, just don't put alot of load on it, slip it, and be easy on the highway. Try not to let off the gas, hit it, and let off again while it's engaged on the highway.

You will get alot of different opinions and experiences, by mine I know to break them in. The clutch in my Honda was stock! It lasted for 2 years and still held perfect until the car was stolen. It had many runs at the track on slicks (70+) and countless street races in a 12 second car and was broke in by me.

 

Let us not forget, we're talking clutch disc break in, not brakes. The reason I state this is that the lining on the clutch will not "wear" in like brake pads/shoes. There is probably only @ .120/.130" lining on each side of the marcel(Metal between the lining). The disc isn't going to slip and slide while driving...If it does, there's a problem.

 

if you put in a new clutch and it immediately slips like a blown clutch you have a major problem! just go by what the manufacturer of the clutch says for break in. i personally like six puck disks. i can't wait to try out my new sintered iron full race disk
