Zoom clutch.....the good, the bad, the ugly?

Zoom clutch.....the good, the bad, the ugly? - 01/20/10 05:10 PM

I don't know anything about Zoom clutches but would like to hear experiences with them. This would be for a street car ('76 Dart) with a stout 360.

How do they compare to say, Centerforce, or any other quality clutch?

Thanks

Not that i've ran one, but they have come along way with there clutches, i ran the Centerforce in my Camaro & it worked great, but i know of others that run the Zoom's & like them too.

Hopefully they've made really significant improvements. I had a Zoom in my old 426 street hemi a long time ago [ 1970 ]. It didn't last long and pulling the tranny in a '66 was a PITA. I've heard good things about Centerforce, but I've never used one. McLeod seems to be OK although I did break a spring in a McLeod disc in the 'Cuda. I am using a Sachs now and so far so good.

I will never run a Zoom clutch again. I bought one for my 340 Dart. Resurfaced the flywheel and installed the clutch. Took it easy for the first few miles. Then when I brought the rpm's up I couldn't push the clutch pedal in. It was like something was preventing it from releasing. Called Summit and they were great. Sent another one right out without me sending back this one first. Well I put the other one in and guess what. Same thing. This time I bent the Z-bar ball lever on the bell-housing. Called Zoom. They have no clue. Told Summit I don't want another Zoom. I got a Ram setup. This works great. I will buy another Ram. Very happy with this setup. These were all Borg & Beck clutches. Zoom wanted me to try there diaphragm clutch but I wanted to stay with the Borg & Beck to keep my left leg muscular. What are the chances of getting two bad clutches in a row. I'm happy with the Ram setup. I don't know if this was a fluke or what. But no Zoom clutches for me.

I've heard from someone else on here the zoom clutches aren't up to handling much above stock hp.

Looks like I'm gonna shy away from Zoom. I'll be researching Centerforce, Sachs, McLeod, and Ram.

Thanks guys!

When I was in high school we had a saying: "Zoom is junk". Not even the Chevy guys would run them.

I have a centerforce in my demon. Remember to remove the spring from under the dash or you need to learn to drive all over again. DAMHIK

We ran Zoom for years when racing the 4-speed.Never had any problems with them.Last clutch I bought was a Ram,but only because Zoom wasn't avalable thru the parts house I dealt with.

you can't go wrong with the Sachs,...they can really take abuse, I run the Sachs 3 finger BorgBeck style 2800 lb diaphram and the Sachs Kevar disc behind the Keisler TKO 600

no experience with zoom, but I did roast my hayes street/strip clutch with a 3500 rpm clutch drop in 2nd gear on the TKO-600 with 3.21 gears and 28" tall tires.

oops.

put in a CF DF and I've been happy with it so far.

Thats what i thought, you'll hear good & bad, even on other brands, i've heard horror stories from the chevy crowd about Centerforce, but also great things, i installed one, it was just the lower line disc., no ceramic, i broke it in & let it rip on the bottle at the track with Hoosiers, worked great.

The Zoom in my 65 lasted about 5 months and thats when it was almost stock.The McCleod was good but used a lot of leg muscle.It has the CF now and is easy to push and handles 600 horse.Been in 3 years and no problems.Next Im trying the McCleod dual disc.Rocky

This is my first experience with high performance clutches and a 4-speed in an old Mopar so I need all the input I can get.

If you want the absolute lightest pedal and able to hold 800+ hp with no chatter, and silky smooth engagement,....do what I did. Go with a Dual disk McLeod RST. Sure, they cost a bunch more, but I couldn't be happier. It's a TRUE street strip clutch. It's like driving a late model car around on the street, but can handle a TON of power. Never slips!!!! I've dropped the clutch at 5000rpm at the strip and it never slips, with my low 11 second Dart.

but your dad uses the CF DF! when I picked up that old 440 block he had in the shed out back, I was asking him about what clutch he uses in that 600 horse? 3800 lb B-body of his, and when he told me about the Dual Friction, I decided to give it a shot when my hayes went out.

Re: Zoom clutch.....the good, the bad, the ugly? - 01/21/10 03:03 PM

Yes, He uses the CF DF and it's a fantastic clutch. He has had very good luck with it. One time it started to fall apart (lining material) and he sent it back to CF. They replaced the disc for free. He still uses it to this day. Very nice clutch.

I never really liked the ON/OFF feature of the clutch when driving around town. It has a very very narrow area where you can slip it for pulling out at low rpms and such. As with anything, I'm sure the more you drive it, the better you get at it. So it's not a bad thing at all. I just didn't care for that.

SO I upgraded (after a ton of research) to this McLeod setup. The engagement window is much more broad and it is very smooth. Makes it very easy driving around town. I am very happy with it. I don't know of any other mopar guys running this clutch, but a ton of mustang and ls1 guys run it,...for a reason. It holds up to their big power and the do indeed run these cars on the street all the time.

For $700, vs $350 for a CF,.... I'd do it again.

Had a McLeod in our circle burner 360/3 sp. Upon later dissassembly the disc was burned & never missed a beat.

With a name like 'Zoom' what do you expect? I use McLeod in all my big blocks. And yes I race them.

I have had three, only 2 now. The first lasted for 10 years. This is not behind a 600 hp engine, its worse than that. A measly 350 to 400 HP 440 in a 4x4 truck that I forced to pull 3rd gear when I needed that wheel speed to climb X hill. When blasting dunes I would slip it like you would a dirt bike to gain RPMs. Truck pulled every year at least! twice. Generally abused it every time I drove the truck. So what finally did it in .018 dish in flywheel hot spots on flywheel the size of golf balls. NO! It pull started fully loaded 18 wheeler,RVs and tree stumps.n It gave up one day just a normal day like every other day. It was a daily driver to boot. SO I bought another, thought 10 years was good service. I have one in my duster it only makes 400ish HP its 422 ci. Ive dropped the clutch at 5000+ in 2nd it just boils the 28 inch bfg drags through the 3.23 gears and TKO 550 trans. I WILL NOT ENDORSE things that perform poorly.. The CF DF is one of the best products I have ever used.
I had tried stock NAPAs one pull toast. I got serious I called Hayes, they said street truck and pulls got just what you need a ceramic disk used there F/W & T/O bearing. It chattered violently P.O.S.. I called them to return it they told me NO and nothing was going to do what I wanted with out some issues. Called C/F they guaranteed me I could return if it chattered,if it wouldn't hold they would make it RIGHT. I don't know if they would have? because its every thing they gave there word it would be. This was back when C/F was just starting out not many dealers. Thats why I am a repeat customer.
There are some set up issues though. You must have enough free play for the centrifugal weights to travel after engagement. Free play at 3500+ rpm. The fingers reach out towards the T/O bearing if they dont have room to continue out you do not get full benefit from the weights. Oh I went with the corvette sized clutch and aluminum flywheel in the Duster for quicker shifts and revs. Very satisfied.
Good clutch and happy hide boiling.

I hear Mcleod is the way to go. Call Passon Performance or Brewer's Transmission and they'll give you an honest answer. Wanna say that passon said mcleod is made in the US also (could be wrong though)

Give us a call, we can fix you up with a good Mcleod clutch!
