my clutch is done from 4wheelin and i need to get a new one.
so does anyone know of a good clutch that is heavy duty, and wont heat up and burn? a clutch that is made for off roading.

-thanks

i like my centerforce its been holding up pretty well or you could try a marlin clutch

welcome , i couldnt post on your other thread

centerforce is what i use. or one from performance products.com

NorCrawler

kind of on a price limit, so anything under like $250 is great.

and correct me if i'm wrong, but don't you have to replace the flywheel too when you replace to clutch??

thanks guys.

Likely want to get the flywheel resurfaced with the new clutch. Make sure that the shop gets the right step on the flywheel face.

you must get your fly wheel machined.. but dont need to replace unless your isnt in spec anymore...

its like a brake rotor.
i ave just sanded with emery and had sucsess if you change your clutch before it gets to the rivets making marks in it.

my flywheel was cracked from 33's with stock gears and lots of wheeling make sure you check.

NorCrawler

would it be better just to get a new flywheel along with the clutch?

That is an option if you are short on time or have no place to resurface your old one or are unsure that it is still usable. I got a new heavy flywheel when I had my clutch replaced about 9 years ago. The heavier than stock flywheel is nice in that it makes more usable torque down below 1000 RPM for crawling (keeps the engine from stalling so much).

LUK makes a great clutch and they make many of the various OEM clutches.
The Centerforce clutches are really designed for higher RPM's.

Mmmm, probably a technique and/or too tall gears problem..

A heavier flywheel does not increase the amount of torque that the engine can produce at any RPM. It does moderate the crank speed and can, therefore, help produce "smoother" driving at lower RPMs. A heavier flywheel does impact the speed at which the engine can increase RPM's (slows it down)

I got a Centerforce Stage II and it works awesome. Had my buddies shop do it along with resurfacing the flywheel. If the shop knows how to do the clutch, they def. know to resurface the flywheel. Just make sure you say something about it.

Just my $.02

P.S.

I have 33x12.50's and stock gears (for now, 4:88's coming soon) and my flywheel didn't look bad at all. Didnt do much hard wheelin like norcalsvx (he's got a few nice videos)

NorCrawler

my technique is good i've been told,
problem most likely is that the clutch was old, stock, and i have stock gearing.

Buy a clutch and flywheel from a 92-95 truck (larger diameter) and you wont have the cracking issue anymore. Its a bolt on imrpovment

That is what I meant by an increase in "useable torque". With the stock flywheel on my truck, I found that below about 1000 RPM, it was very easy to stall the engine while off road, or even on road. For example, I could not idle up my ~5 degree driveway in 1st gear high range, only in low range. After installing the heavy CF flywheel, the engine will easily idle up that same driveway in 1st gear high range. Off road, you can feel the engine bog down when idling over something like a rock but instead of stalling, that heavy flywheel keeps it turning over and at the next cylinder firing it is off and running again. It is not a huge difference, but comes in handy on some trails. For example on the Dusy trail in CA, there is one day where you hit long stretches of easy terrain then a few rocks to negotiate then back to open trail. Being able to let the engine go really slow and idle up over some of those sections without having to drop into a lower range in the t-case makes a big difference by the end of the day (there are probably 100 of these sections). The first time I did that trail with the stock flywheel, I was beat at the end of that day. Next two times I ran it with the heavy flywheel it seemed like a breeze and way several hours faster.

And yes it does slow down revving of the engine, but with 120 HP and 4700 lbs. of 4Runner, that is a minor issue.

Advanced auto on the east coast,has a higher end brand which is made by Zoom,replace the flywheel,with a new balanced high end part.

has anyone had the heavy duty clutch from marlin crawler?
was it good/bad?
how stiff was the clutch?

norcalsvx

i thought it was pretty harsh myself (i got the HD on a 81) i like the centerforce pedal feel much better.

norcalsvx

i cracked my 94 pretty easy with lots of wheeling and stock gears.

Thats probably from all the mods you have that give you like 300 hp! Do you have 4.10's with 33's or 4.56's?


The previous owner replaced my clutch about 80,000 miles before i bought it, and let me tell you, i have burnt that sucker quite a few times. Im surprised its still going, since it has 80 something thousand miles on it/ i learned to drive a clutch on it/ and the amount of wheeling i do with it.

Anywho, when mine goes out, i think i will go with the marlin crawler HD clutch.
